- This is actually sold as a complete product ready to go, but as with many of these things you really have to treat it as an unfinished product and do all the final bits yourself.
It does offer very good value for the components though, and is an ideal base for many personal outdoor projects.
I wonder where these are actually used in real life. Do people install them as wall mounted alley lights in China or even as pole mounted lights for actual path or street lighting?
Some afterthoughts...
The screws that hold the LED panel onto the back of the housing were very short and two stripped their threads while being tightened without excess force. Not sure the size, but an M3 screw wasn't a direct fit.
The earth connection was the same screw and the same inadequate tapped hole as it often is. The factories that make these don't seem to understand that attaching the earth is supposed to mean a solid electrical connection and not just to keep it loosely out the way.
For those that will inevitably say that it will be grounded by the pole or wall bracket it's mounted on, there may not be a ground on that either. Especially a wall bracket.
If using this panel I'd downgrade the driver to 20W, attach the earth connection properly and check that the panel retention screws were holding it in place properly, replacing them if necessary.
Other than that, the fitting is an interesting twist on the older units with classic 1W LED beads and discrete lenses. The use of a traditional driver is interesting, as I was expecting it to be a DOB PCB (Driver On Board) using the simple current regulation chips.
The seal on the front looks decent and theoretically the position of the flex entry hole should prevent water ingress while allowing the fitting to breathe.

Love the image of bang good sales rep left baffled by the Scottish chap who turned down phones and drones and asked for a streetlight. The legend of Clive reaches the Orient.
If I found a lamp that was warm at night, I would build a nest on it too.

Last week I saw a pigeon shuffling along an led streetlight. I watched to see what he was doing. It had figured out that if he sat on the mini photocell in the lantern top, the light would come on, and he'd get warm! Clever bird.
They ride trains as well.

@@FarleyHillBilly don't be silly
A pair of those lights with a dimmable driver appear they could make a lovely workbench illuminator.
Exactly my thoughts, I think I'm gonna order some of these and do some experiments on them as workbench lights.
@@kazumahikineet3090 Would not those LED floodlights be better ?
@@kazumahikineet3090 I hope you post your results.
I think they'd be great as a yard light for property, nice light for illuminating an entrance
@David Pumpkini With foot stirrups?
Asking for a friend.
Technically your screwdriver is still cordless
noooo you didn't
Hahahaha...
And, it makes a sound...
If you mount it perfectly level, it will fill up with water, and you have a water cooled streetlight!
Where does the water get in?
Even better if it was snowing?!
SkyWizardless check 2:35 , it would just pool up not actually get inside
Check out LiquidLED, they actually use liquid cooled lamps. Dunno if they make street lights though.
@@mrOGmixer That's exactly what I thought.
I always feel slightly disappointed when I see a Big Clive video about something reasonably well-made, with no major, showstopping hardware bugs.
the loose driver is not good when placed in position it will be sitting on the white thin plastic, not connected to anything. no ground on the exterior metal case of the driver. and to be IP65 it must have something that seal the hole of the wire. in the long term, overheat and humidity will corrode the internal part exposed :/
That's not bad for the price.
I think if you know to open these up and check them out you can catch and fix things like loose grounds.
Great stuff as always, Clive!
That's what I do with stuff from China.
The real problem with that approach is that these markets are open to every Tom, Dick or Suzy. A lot of people out there are barely able to change a lightbulb and just don't expect to have open up an item sold as ready to use.
This is great for you and me, but not so great for the accountant down the street who doesn't know diddly-squat about electrical safety.
We could just let the Darwin Awards deal with it though and the problem will correct itself.
@@QlueDuPlessis Remember from our parents/grandparent's generations when every man was a handyman to at least some degree? I don't mean that everything about the past was great, but there are some parts that'd be nice to bring back.

Watching this and thinking

Great video, really enjoyed watching this. So therapeutic. Thanks Clive
I have always had an interest in streetlights and lighting tech and love watching these teardowns!
A lot of people are fond of street lights and collect them.
Yeah, we've got hundreds of them around my town.
Oh. Right. Yeah.
I came here for the soothing Big Clive voice and I wasn't disappointed.
Is the 'R' silent ?
I love these lights. I have a couple of the 100 watt ones and they came with remote controls. One is mounted on a 20 ft pole in my back yard and the other is on the side of my house. Very bright.
I've watched like 20 of your vids, and I'm still not totally sure what your channel is, but I love it.
Ive worked with streethlights in the past and philips does a style where you can order them with drivers thats turned down abit, and they have an entire chart of how much loonger the LEDs last depending on how much youve lowered the powersupply.
Also those have a thermal sensor in them wich will cut off if the LEDs gets too hot in the summer, we had a few reports of them not working and foundt out that it was because some of our controll boxes was running an old timer and it had goten out of sync with the daylight time.
Sounds like the xitanium programmable drivers.
I like that the cable opening isn’t sealed because if water does happen to find its way in, as long as the cable slot/pole hole is open then it can evaporate instead of just staying in there and corroding like hell.
There’s no such thing as waterproof. Water will always get in. Or air will condensate with rapid temperature changes. Leaving moisture inside. So Leaving a bit of an exit strategy sure helps things air out and last longer. That’s been my opinion spending several years repairing industrial electronics that have been long used and abused.

thanks for the video Clive if i needed a lamp at my home i for sure would look at buying this one
I love your videos because you tell q story while you work
Clive is illuminating the streets of the IOM one lamp at a time ;)
New favorite Big Clive quote: "Shove it down the lamp post."
That silly little pre-wired flex looks like a pain for installation. Much prefer proper terminals to having to make a join in the arm/column.
They are. On those Chinesium lamps I remove that cheap UK/EU flex and put in a longer US color coded lead of a better quality and bigger gauge. The termination is done via a pole mounted box. We don't use the wabco? (sorry I forgot what they are called) terminals int he US to join wires, though they are an option, We use the wire nuts and tape.
It's intended for multiple markets so adding any particular connector would add cost and annoy more users than it benefits.
@Kryštof Píštěk what do you mean by a terminal? Sorry if that's a dumb question.
A connection block with screws.
@@larrylentini5688 A basic terminal block with screws, a fancier one with Euro-style set screws, or rising-cage type screw connectors. Anything that allows you to discard damaged leads and replace them.
A simple wire coming out of an epoxy-potted circuit is very susceptible to breaking inside the insulation at the edge of the epoxy, and there's no way to replace it short of throwing out the entire driver.
You have an outstanding camera! No significant bloom with all that light right into the lens!
Cheers Ron! You are an amazing artist and I look forward to your videos more than almost any others. My hat is truly off to you with genuine respect.
I noticed that you can see a dim reflection of the LEDs in the bottom right corner, but other than that, the picture is really good.
Moto G7 power.
A nice enlightening video.
5G death beam?!? Ah, no wonder we can see the disembodied spirits of alien ghost orbs when you turn this streetlight on. Quick, someone get me my Gwyneth Paltrow candle to make it go away! :P
And i goop....
11:24 - I can see your breath. LOL
As Peter S commented below, slapping a dimmer driver in one of these would make it much more useful. I could see mounting it over a workbench, or maybe mounting it to a good microphone stand to make a portable worklight.
Watching Clive makes me really wish I persuaded a career electrical engineering or at least became an electrician. I don't understand what any of it means, but seeing him take things apart is so interesting
Apart from the usual earthing issues from Chinese imported appliances, this fitting is pretty good quality.
touch with back of fingers ! so if its live your fingers wont grasp onto the appliance ,very wise man
I, live on a farm. We have several of the old style sodium lights to illuminate the yard and cubicles. Assuming that this is a fit for our existing brackets it could be useful. I think our existing sodium lights are 50 watt, so these wouldn't save any electricity, but would be much brighter.
I have a similar one in my back yard. Going 2 years so far no issues
Good Review and Multi meter test... Don't forget to tighten the frame ground wire..!! LOL
I remembered that AFTER screwing the LED panel back on. I did take it off and add the required washer, as the hole was not deep enough for the screw.
You missed it Clive!
Those two fixing screws are the earth that is why they are so tight! they pick up the earth from the lighting sanction which is earthed at the cutout at the base! ;0)
For those not aware this is a joke about the Chinese Safety Standards (or more accurately lack of) ..... bu the riser tube that the light fits on would presumably be of metal and would also be earthed!
It is interesting to think of what this unit would replace (sodium light) and what was involved with those! I can remember as an apprentice being ridiculed for suggesting there was such a thing as a High Pressure Sodium light ..... The Engineer was a bit old school though ;0)
Thanks for that, Clive, I might just consider a pair of these to replace two of our 35W SOX lamps in the yard. At the price of these LED lamp heads, you could get two of them for the same price as a single 35W SOX "bulb" so even if they lasted only half as long, they still would not cost any more to replace, though it would be weird looking out into the yard and seeing it lit up in white!
Sell the tubes and ballasts on Ebay, they are useful if you are making optical flats.
There are other styles available that are at least a bit more serviceable because they use the square format 10 x 10 chip LED arrays.
There's a good chance that an old SOX lamp will greatly outlast a modern LED lamp.
I would rather keep the sox lights, they are starting to get quite rare now
@@bigclivedotcom I'd say there's more than a good chance! - They've given us 25 years service so far, only ever needing new "bulbs" but they're getting hard to find in the local electrical wholesalers. To be honest, I much prefer the amber glow coming through the windows at night, but our CCTV "sees" better with white light, at least, until the IR floods kick in.
We are trialling that Philips "True Force" (Xitanium driver) at present, but they're not as cheap as this one.
@@alistairstuart2009 I quite agree, and that might yet be the case. I have my own "pet" lamp that we keep as a spare, but the CCTV sees better in white light during the twilight transition, until the the IR flood lights come on.
For the USan, 45mm ~~ 1 3/4 inch.
After Clive did a review of the solar-powered street lights, I bought one (claim is 60W) that uses the LiFePO₄ battery. That was about 9 months ago; it's still going strong.
I've got one of those potted Chinese ballasts and can confirm that it works on 120VAC just fine, in spite of the nameplate rating. I use it to drive a 50W COB LED.
@M Harris Could be--I haven't bothered to put a meter on this one, as it operates just fine on 120V--that is to say, don't look at it directly if you value your vision. The project has stalled a bit but I'm intending to use the COB (and heatsink and fan) to replace the 500W halogen in a upward-shooting torcherie floor lamp. The ballast unit doesn't get warm at all.
13 screws reminds me of when I was in college and took a computer organization course that was taught by a woman that was born and raised in Russia (Soviet Union back then). We had to keep an eye on her whenever she wrote binary numbers on the board, because while she spoke fluent English, she was mentally translating Russian into English, and would sometimes write too few or too many digits on the board while counting them out loud. "1,2,3,4,5,6,7,8." "Miss Kartashev, you wrote 9 ones, not 8." Maybe Clive is translating from Scottish to English? Lol!
@M Harris I think something may have got lost in translation there.
Do they have surface-mount versions of those multi-color cycling LEDs? I'm not too sure how well they work in series, but it'd be pretty funky to have a multi-colored street light outside your door.
For the price, this is quite awesome but not sure if water will get into it via the mounting hole. It is also strange the upper shape is not letting water flow off naturally.
Hi @BigCliveDotCom - many thanks for another great video.
Just now, I've been asked a question that I don't know the answer to - hopefully you and/or your viewers may be able to help...
How possible / wise might it be to try to make a PCB using either laser or chemical etched acrylic mirrors?
Preferably, the components would be on the reflective surface.
We are aware that the tracks would need to be much wider than a typical copper PCB's tracks.
Many thanks for any advice that may be available.
"I asked if I could have a street lamp".
Bangood must've been completely bamboozled by that. People always go for the "shiny factor" but not clive. Clive choses the weirdest stuff because he can :D
PS: I didn't even know you could buy streetlights. It makes sense for the back yard or garden but didn't think they would be streetlights then.
Black3ternity the city council’s gotta buy them somewhere.
I can imagine this sexy black matt fixture on a street with no trees alongside to shade it in some bulgarian village that has over 300 clear sunny days in year (at mountainfoots at about 700 to 1100 meters above sea level most of them have this sunny feature, but at least evenings and nights there are pleasantly cool) in a summer evening at 20 hour being turned on and suddenly all these diods have to radiate generated heat via preheated to 50-70 degrees casing to an air of 24-27 degrees and this driver in a box that is just dangling in there.
One should design for the worst case scenario. Then over engineer it by 50%
Make it look pretty, easy to manufacture and cheaply
I worked with a guy called Nash. he seemed to think that way
@@FarleyHillBilly In my opinion any design makes sense only when it targets real life application and follows strict design rules. By no means examples such as this one are fault of chinese designers or businessmen - it's a matter of policy and any policy is driven by demand of social aware citizens. It's especially painful to understand and even more to implement rules of compliance in poor countries as mine: it's not coincidence I have mentioned Bulgaria - I am bulgarian myself and in the dark age of socialism there were obligatory technical standarts for almost everything but with the personal and political freedom for some unknown to me reason came the freedon of not following any standarts. It's a very long talk and probably off topic, so I'll stop here.
@@deepblueskyshine
I understand.
After that last video, I'm waiting for you to point out the 'earth', then pull out a tiny globe. =D
(Insert environmental joke about 'Chinese industry and their inadequate connection to the earth' here.)
If your putting that light in the garden theres possibly room for a wifi extender in the casing or maybe a bluetooth control module so you can turn them on and off individually from a mobile.
Will you be doing another meet up in Glasgow this year?
I hope you can!
Yes I will.
@@bigclivedotcom YASSS! THANKS BIG CLIVE!
I'd curious about the spectrum of light output. Cheap sealed unit grow light?
Love you videos
Clive, can I suggest adjusting the shutter speed on your camera to avoid the flicker on your meter's 7-segment display?
Also, you said "I'm not going to use a cordless screwdriver on this?" but I don't see any cords on that screwdriver
You did use a cordless screwdriver, Young Clive 👍
That’s pretty impressive for the price.
Where can you buy the replacement led panel for the street lights. I have 2 I P65 lights that have burnt out after 4 year's.
I use the technique for sealing Heliax on radio towers. You could use the European screw clamps or decent wire nuts from the USA. Use Scotch 3M type 33 electrical tape over the joint and outer sheath. Follow this with a layer of self fusing tape followed by another layer of 33 tape. Now get your can of Scotch Coat and paint the whole joint with this coating twice and extending onto the cable sheath. Scotch Coat is like a rubber cement product that seals even the tape joints. I have never had a bad joint due to moisture in any RF joint or electrical joint. The inner layer of tape allows one to use a razor knife to cut into the waterproof seal and peel off everything if you need to change out the fixture.
I would think that Scotch 3M products are available in the UK but not in continental Europe.
I just use duck tape !
Hi, I have a question related to 6v diodes. I removed two strips with 7030 LED diodes from the old TV. Each strip has 44 LEDs and I wonder how can I connect them to 220v?
I kept looking at the heatsink fins and thinking how they could have been designed to reduce water/dirt/debris retention. Would be interesting to do a thermal test to see how hot it gets? Perhaps even simulate outdoor conditions to see how much effect bird poo etc would have on heat dissipation...
Can anyone explain how all these lights function with a driver that has such a wide output voltage? Do they sense the leds some how? I have a pile of these that I have been collecting from a lighting outfit and can't seem to figure out how these are rated so oddly.... I noticed some have the option for dimming so I get that would make it variable but the ones that have no dimming options still have that voltage swing. I have a few I need to replace the drivers in and no clue which ones I should get because of the mystery voltage.
Even the earlier generation led streetlights were OK for domestic use. Bought two from DX a decade ago, and although the casings are falling to bits, the electronics (and led boards) still work just fine.
That's pretty good. Are they the type with discrete 1W LEDs?
@@bigclivedotcom Yes - and here's the review of the lamp in question. ruclips.net/video/8dxqRiXFGC8/видео.html Yours were from Banggood, whilst ours were from DX! The grey paint has been replaced by Hammerite (a few times!) yet the guts are still OK, and the LEDs still produce a useful amount of light.
LOVE IT !
I've seen a LED light with driver on the aluminium pcb flicker after just a year of intermittent use.
It went from warm white to a dim purple light and turns on for half a second every 2 seconds or so.
08:56 "Lets take a look at the LED array". I think you meant "5G mind control array"!
I was so tempted to make lots of brain modulator beam references.
@@bigclivedotcom Can we have a brain modulator beam teardown and reverse engineering in the next video? I'm building one at home but can't get it to work right. It does scare the cat but I still think the government is awful so it's clearly not working.

Nice.
Hey Clive, would it be possible for you to maybe look at some older Low/High Pressure Sodium street lamps?
There's not much in them. Usually just one ballast.
The older blue mercury vapour streetlamps would be fun, too.
Annother informative video. I've just ordered the 100w version I will get back to you and let you know if it's actually 100w. It's listed as being physically larger than the 50w lamp
Nice little unit there. Apart from checking all of the ground connections etc, that's pretty decent. Depending on requirements I'd be tempted to keep it at 50W and just hope it doesn't burn out too quickly; remember that it is going to be used most of the time in Winter (like now) where the outside temperature at night is below zero.
yeah, what are your thoughts on 5 G. I would be very interested to know
You need to make a SMALL electric Screw Driver. The Driver looks to be made better then the rest of the unit. LOL
Whenever you show the HOPI and i see the voltage i tend to check our voltage. I have my PC and monitor connected to W meter to see how much money i blow on gaming and youtube. Anyway right when you sayed 248V that is out voltage i looked at my meter and it is showing 252V. Kind of high, since they changed our transformer from 22 KV in our village. We got a new one because there is a house building boom and the old one was not able to keep up with rising demand. We might became a small town instead of village soon :-D. Just a funny story from Slovakia.
I've yet to have anything from banggood that goes band and makes me say "good", things I buy there always seem to work, after tweaking and some minor shipping damage repairs of course... :P
Last longer, I have had led lights last a while, a dollar tree light lasted 4 years of constant duty! And it could probably be fixed! The LED's in one were all still good, something in the driver let go,
Hey, are you able to put a link to the listing? Tbh, for the price might be worth having a few 😉
I need a couple of these for my driveway and backyard. For security.
Whatever you pout up, make sure it's at an accessible height for repairs and swapping. Modern LED technology is not as reliable as claimed.
@@bigclivedotcom right, something like you've reviewed before.
@@raymondmucklow3793 I got some of those Aldi bulkhead lamps Clive reviewed.. more than adequate for any domestic application and I think Clive gave the internals a clean bill of health.
@@bigclivedotcom You can say that again! Our local council upgraded us to SOX in 1978, and they served us well, until 2016, when they were replaced with LED, and again in 2017, and again in 2018. The current ones, it must be said, have faired better, but it's a long road to the 38 years we got from our SOX lighting.
@@28YorkshireRose12
I doubt the lamps lasted 38 years.
I do believe there should be a cover on the back of the light to prevent birds building nests on them. At least i don't see any bird nests on street lights where i come from. The birds usually build their nests under the bridge or under a roof due to snow and stuff.
That heat sink would get full of Bird Smoooop.

@@dustysparks Thanks for reminding me of that video, hilarious.
Comes out as “12 screws on top of as usual.... oh I’ve said one of those words that RUclips doesn’t think ”. 🤔
I think you’re safe Clive 😁
Servicing would hopefully consist of replacing the whole board, no more, no less. But is it available?
What temperature do you define as _baking hot_ on the Isle of Man? In Austruckingfalia, _baking hot_ would be anything above 40°C to 42°C. In summer in certain regions, 25°C is a mild day and 30°C would be a warm day. Even 35°C can be describe as pleasant unless it is blowing a hot wind then it becomes a tad too warm.
The mounting screws should be on the bottom and not the top shouldn't they? To prevent or at least lessen the chance of water ingress?
Oh and thanks for the cheese video, You had me up late barbecuing cheese with a TV set flyback after that and stinking up my house... All in all it's good mad scientist fun though.
Clive, your thoughts on earthing requirements - as the LED driver's double insulated. So it's only the wires to it that are an earth fault risk ?
There's no guarantee that the output is properly isolated. I've also had a light that was supplied with the live wire pinched between the cover and housing.
@@bigclivedotcom And I've seen the video with the trapped wire ! Not that uncommon with UK 3 pin sockets mounted in walls - where a cover screw grinds its way through conductor insulation.
As for the output, two thoughts - the double-insulated classification should cover those too - "double-isolated" :) and the fact that all the LEDs light would suggest there is no power leaking to earth - unless the last LED's 'return' is connected to earth instead - but if it was and they're still lit, it must be a 'good' earth !
I've (Pun warning) always considered that isolated 'LV' has the 'potential' to float anywhere between 0 and mains when isolated. Hence why when I installed shop display lights in a friend's bathroom, I connected 12V output N* to E and used the green/yellow core for that to each of the lamps.
So on the one hand a bit naughty using earth cable as a power conductor but at least it was also a genuine earth!
(* As determined by the fact that output L fed 3 fuses, one for each lamp !)
(Can't even remember now whether the output was rectum-fried - no need for halogen bulbs - so logic would say not.)(Bit of a bastard transformer - labelled as 150W - and the consequence of using 30W bulbs was simple - it'd blow them. It needed 3 50W bulbs to bring the voltage down !)
@bigclivedotcom You've mentioned swapping the driver with one which is lower wattage. What percentage reduction is suitable for prolonging the life of the light without degrading the brightness. Would a 40W driver instead of a 50W be enough of a reduction?
That would definitely improve the lifespan, but even with a 20W driver the intensity would be very useful because the LEDs are more efficient at lower current.
"You can have anything from our shop. So what will it be?"
"Can I have an UV lightbulb as well as a self-heating showerhead please?"
Nice street light really, specially for the price..
Hey i have a few strand permus dimming modules could i send some to you to do a video on i have some small green ginger dimmer packs too would love for someone to do a video on some old school stuff
The driver is marked 10S5P ; I would have thought that means 10 Serial X 5 Parallel - 10 sets of 5 LEDs wired in parallel, but you seem to suggest that it's 5 sets of 10 parallel. Could you clarify please? :-)
Also, could you explain a bit about the difference between dimmable and non-dimmable domestic LED lights and dimmer switches? Many thanks!
Clive, in the common 12V LED strip, there are 3 LEDs in each section and an SMD. What is this SMD (capacitor? resistor?) and what is it for?
It's a current limiting resistor. Usually around 150 ohms (151)
Hi Clive sorry to ask a question not relevant to this. On your recent mega live stream you showed a SMD Hot Plate you had purchased from China. Really would like to hear your thoughts on this item as you get a chance to test it out. Certainly, as you noted is a great price for us in the hobby arena. I understand everything takes time and making videos need planning. Thank you for your interesting videos and ideas you share freely.
I've not tested it with soldering yet, but a friend got one and found it worked well. I've had a look inside this one and it is designed sensibly.
I've only heard of 5G paranoia on this channel, everyone I speak to though work seems to think they have it already but it always turns out to be 5GHz WiFi. 😀
Yeah. And people who used 802.11a had 5G nearly 20 years ago 😂
Won't they be jealous of me! I have 5.5G EXT service at my house! That extra 0.5 plus the extra letters mean it's more betterer!

@@tin2001 true and people who used 802.11a are likely technical enough to understand the difference. ;)

You should get a sheet of completely exposed X-ray film. You can lay it on top of the bright lights.
clive really out here reflowing 13 pound led streetlights
I should have sent you the GE hd+ Led that burst into flames at my house 4 days after running. Would have been nice to have dissected. I dont think they handle the variation of power very well.
Clive, some places are installing amber LEDs in place of traditional sodium lamps. Would you be able to tear one of those down at some point?
I looked at a sodium (SOX) retrofit lamp recently. The yellow version uses yellow phosphors instead of white.
bigclivedotcom Ah, alright! Thanks!
Are the screws stainless?
Appears to have the CE approval logo on it. If there's no proper ground is that proper then?
The presence of approval marks on Chinese goods is no indication of safety.
Google 'gutter oil' and 'pig toilet' for an indication of their mindset.
I would love to know the power the old style lamps would use in an average town, compared to the led replacements
There are quite a few variables there. You could try and work it out from an old satellite image and a guess at the power rating.
whats the link to the ebat listing?
Nice viddy dad
only Clive survived the Scottish MRE so he's alone and gets a nice high 248 Volts on his mains :)
You should do a tear down of Quantum Lamp
Banggood: Do you want a drone?
Clive: no, but do you have a faulty appliance?
Come on ~ a "Breather Hole" for just Smoke and Steam escape? I'd hope for delivery of what's cooking too.
If that light got "stuck on" in a hot climate during the day would it cook with it's heat along with the sun on that black paint?
It certainly wouldn't be happy.
Enlightening...
Wonder if I could mod one with RGB LEDs so that it starts off pinky-red and gradually turns yellow like an old skool sodium bulb lamppost?
Or do the random spectral burst of some metal halide lamps.
