In the UK my neighboring council has been retrofitting some the older lanterns like this and I think it’s a much better choice than replacing the entire fixture with a brand new LED unit, although I did see a few examples that failed shortly into its lifetime. In fact I even saw one with a strobing LED corn bulb!
That reflector was designed for a very small tubular light source. I can only imagine how poorly the fixture must perform with the light source so far away from the designed focal point.
I've always felt the old style bulb systems to be more dependable than the new leds made of chineesium that will quickly fail or the rectifier will burn out and it'll start blinking all night.
I would much rather have retrofitted HPS fixtures than just completely scrapping the entire fixture. It’s a complete waste if there’s nothing wrong with them.
They should make them with the orange glow too. There would be an led light in the old fixtures and orange color that everyone likes but still being led so it still has energy savings. People won’t see a difference in it. It’s foolproof.
I'm currently retrofitting old hps and mh with these "corn cobb" leds. The replacement lamps are bulkier than the old lamps. So you need to adjust the mounting or reflectors. I've found that a bulkier 60 watt led is equivalent to a 250 watt hid lamp. The 100 watt replacement equivalent to a 400 watt hid lamp is ridiculously large and limits its usefulness. So your led's output is limited by its bulk. The ease of retrofitting is a major selling point for this lamp. It is a whole lot easier to retrofit these fixtures than to replace the ballst assemblies. I have found that the light output to be less than the hids it replaces but it is offset by the ease of retrofitting. NOTE- I see in the video that the installer is inside a metal caged basket lift. A fiberglass bucket truck is a whole lot safer.
Nice. But if I was in your shoes, I would've removed the capacitor and ballast all together rather than leaving them in the street light 'cause it's kinda redundant to leave them in there. Plus the ballast adds weight. That'd make the street light not as heavy 'cause the ballast is the heaviest element in it.
People say these bulbs don't put out good light but I've seen these installed in lights and they seem to look exactly the same in light output. besides the reflecter inside the light reflects the light back out of the light which means the light is being redirected onto the road. I think there a great retrofit to install.
@@JonathaninEssexFirst, this comment was from two years ago, second I work on this kind of stuff and have these older fixtures. I know how to install these types of lamps in these older fixtures. You can't just randomly say my comment is ignorant when you clearly haven't done the research. Do you even know anything about streetlighting?
Let me get geeky for a moment... I wonder, have you taken a fixture down and sent it to a photometric lab to see how the light output compares? Cobra head efficiency runs around 60% with an HPS lamp, and it certainly will go way down with that screw-in LED. Any light that is going above horizontal into the reflector will likely be lost. A 250W HPS lamp puts out around 27,500 initial lumens... at 60% efficiency, that's 16,500 lumens that make it out of the fixture. The LED you put in - 55W - Probably puts out less than 8,000 lumens. At 60% efficiency, that's 4,800 lumens that make it out of the fixture. So in the best of situations, you're reducing your light output by 71%. It'd be different if you were putting up an LED-specific fixture, as they are rated differently. The lumen output quoted by LED manufacturers are "actual" lumens - there is no multiplier for efficiency. So you could use an LED fixture with 16,000 lumen output and *then* you'd be putting up something equivalent to 250W HPS. That'd be in the neighborhood of 110W-150W LED at this time. Good luck with future retrofits. Thanks for sharing the video!
sir agree with your point.from china ,if change LED bulbs the lumens goes down,and for the efficiency for LED should be higher than 90% most of them we install in china.the inside wire connection is better then chinese works.lol. thks for sharing this video.
@Fact Checker not saying it'll directly cause deaths but if the DOT has a spec for how much light should be hitting the ground, after the retrofit it's unlikely they'll still meet the spec, which could open the DOT up to liability in the event of an accident. Don't get me wrong, I am 100% in favor of LED, but it's important that it be done correctly. If the state has no illuminance spec, fair enough... But if they do and they fail to provide their own specified light levels, that's where they can get into trouble.
I don't it is either Westinghouse, Crouse-Hinds, or Cooper street light fixture. The reflector, and the lens are the same as the Westinghouse street light fixture from 1966-1979, which are 30 inches long.
These are a joke. Here in the Virginia-DC area they do this with some of the highway lights and it’s extremely stupid. They are way dimmer because they are meant to magnify a small point (the arc tube) so putting a bulky corn cob bulb is stupid. Just use a 4100k cdmh bulb and that will work the best.
Instead of retrofitting, you should’ve bought an LED fixture and sold that luminaire. The bulb isn’t going to be direct as an LED fixture so you’re losing more lumens. Omnidirectional bulbs are obviously a no go for LED or any light source.
eww why would you decide to force this person replacing the whole fixture with an LED On it in my opinion it's even much better Retrofitting Than Replacing the whole fixture with an LED on it
Too bad half the light from this LED COB lamp is wasted in the reflector. I would assume since this video was made, this fixture has been changed out to a new LED fixture. Those LED COB bulbs are inefficient.
Definitely not GE. Can't tell whose though. Here's a link to GE's corn cob. Which, by the way, is also not suitable for use in horizontal lamp fixtures like cobra heads (for efficiency reasons if nothing else). www.gelighting.com/LightingWeb/na/solutions/led-lamps-and-modules/led-replacement-for-hid/
Like he says in the video, there are two phases ("hots"), instead of phase and neutral. The two phases are 180 degrees apart, thus the voltage between them is 240V, even though each phase on it's own is 120V.

They have been replacing the streetlight with led, in my town for the past couple of years. Many of them fail after a year so les.

We don't retrofit, we use mercury, metal halide and sodium, sodium is already energy efficient, why use led?, screw leds
Ban LEDs.

LEDS produce more visible light, so it will seem the same brightness or maybe brighter

Satco makes a one sided LED retrofit lamp with a mogul base for just this purpose so all the light shines downward for maximum efficiency.

It's a Cooper fixture.
It is a Cooper OVX
Did you leave the capacitor attached and the ballast. Or did you have to bypass them
You just bypass

I'm really surprised they are not closer to 90watts in power.
I enjoyed it great job 👍😎

Shame we can't see it in the dark! Is that not the end result we need??? Seems like an obvious one to me.
How many lumens is this bulb?
How do you disconnect the power ?
Sucks, LEDs, at least you just threw in a retrofit, not replace it.
American 015 agreed, he just cut all the wires flush from the ballast.
Good Stuff.Be Safe out there.
To be honest i hate LED but that retrofit LED light bulb is cool
Hey why don't you install a equivalent 750 watt corn light led bulb in street lamps? It will be more bright safe and you see everything.
Shut up led suckes
What brand in this street light
Cooper lighting
Cooper lighting OVX 250 watt hps street light
I know
You need to show how you disconnect the power
What kind of LED is it? GE?
Definitely not GE. Can't tell whose though. Here's a link to GE's corn cob. Which, by the way, is also not suitable for use in horizontal lamp fixtures like cobra heads (for efficiency reasons if nothing else).

The street light is a cooper lighting ovx 250 watt hps street light
NO NO NO! I don’t like these new LEDs neither does my mom. Me and my mom like the old HPS
well i've seen some old school People that Like Vintage HPS Bulbs i think
Big kitty WELL THERE ALL GONE AND SCRAPPED FOR GOOD AND I SAW ONE GET TORN APART
Fun fact: blue light is extremely bad for your health. Also. I’ve never seen that old light bulb
how come are they 240 unsted of 120v
Some are 120v some 240v but it has to do with the power phase
Like he says in the video, there are two phases ("hots"), instead of phase and neutral. The two phases are 180 degrees apart, thus the voltage between them is 240V, even though each phase on it's own is 120V.
@@martinweizenacker7129 true. But could they just use 110v as a power supply
@@johnhershey4010 Yes, they could.
I really don’t mind led but the old fixtures really matters! Cuz these new led fixtures are ugly
Tennessee's are 110v
These lights are much worse in Malaysia
we have some free led corn bulb,does anyone interested in?
John when and where?
If it's free, it's for me 😁
What a load of rubbish.
