Not a massive fan of these LED retrofits to be honest just down to how poorly they handle running long-term in enclosed fixtures. They don't generate a boatload of heat, sure, but what heat they do generate can still be enough to cause degradation or early failure of the lamp in most cases if the heat can't be sufficiently managed. This, in a watertight or vapor-tight fixture is a massive issue. It's not *as* bad in an open luminaire like the "yardblasters" that are so ubiquitous on the sides of buildings and on wooden lamp posts as they usually provide great airflow, but in an enclosed fixture, such as a low wattage wallpack, post-mountable flood light or a more standard looking street light such as a GE M400 or a Philips SGS203, they tend to fail extremely rapidly due to not having sufficient airflow to keep the diodes cool. And if it isn't the diodes that fail, it's the internal power supply.
250w mercury vapor lamps like that sylvania output 160,000 lumens an LED bulb outputs 30,000 lumens at best. you say it is brighter because the bulb is daylight which gives the optical illusion of the bulb being brighter
When comparing led to HG compressed Mercury the colors are pretty much the same but the HG as it degrades over time starts getting a greenish tint to the color Plus the LED bulb does not need a ballast it's built into it also to further note compressed HG bulbs are just about the same price as an LED bulb but we've had HG bulbs on this property for 5 to 7 years but the light output on the LED bulbs is basically I would say brighter then the HG bulbs
Usually the ballast does not go bad. Normally it is the $13 capacitor that goes bad. The metal halite will go bad after a while. You got a link where you bought the bulb? Does it say on the bulb itself that it is rated up to 277 Volts? Usually they are rated for 240 volts per print on the bulb itself, not the box.
Yes your right about the cap going bad or the starter also . We are replacing them to down our energy cost .Heres the link www.amazon.com/Hyperikon%C2%AE-Lighting-54-Watt-Replacement-UL-Listed/dp/B00S5RXDHM/ref=sr_1_3?s=books&ie=UTF8&qid=1469376277&sr=8-3&keywords=led+corn+bulb As you can see in the pic its rated for up to 277 volts. Thanks for watching .
Those corn LED bulbs are junk. I find them in the trash often around warehouses here. They last about 3 years due to poor design. Don't waste your money, instead buy a new led fixture with the right led bulb in it. This costs a little more but is worth it in the end since it will last 10 years.
Yes I kinda over exaggerated the pricing a little. We are just getting rid of all our merc and halides bulbs .These bulbs are installed in pole lights that is like 20 feet in the air.I have to get our man lift and set up outriggers on the curbs,Traffic cones ETC.... Just to change a light bulb are a ballast.Heres a vid that shows me changing a light. It takes longer to set up the lift than it does to change the light . ruclips.net/video/PFUH20Sg5OU/видео.html
Why is that? Care to be a bit more specific? I just received a 54W 5000K LED corn and so far it's excellent- bright, cheap, and no ballast needed. It is expected to last a long time (we'll see).
@@donnaland197 is your 54W 5000K LED corn light still working so far ? I ask because I'm debating on whether I should buy one to replace my mercury vapor halide light in the backyard. Thanks!
Well...good question. Yes, it works and it works nicely BUT...it's not bright enough to light up your backyard. There is a 100W LED corn cob style light that I would recommend instead. The 54W seemed like a great idea and but I find it's just not enough for what I was intending. It might make a nice grow light or light over your shed (or inside your garage or shed) but it was advertised as being bright enough to light a basketball court- umm, no. Go bigger if that's your intent.
You'll smell burning and ballast and bulb will be trash. How do I know? We had energy upgrade last year in my building. A first year trainee put the led bulb in without taking out ballast. Blew out all lamps. 13 of them in court room. Not cheap! Also because in 2 days we had a large court they had to buy new bulbs local which were much more expensive then through there supplier.
It depends on the circuit. Mercury vapor lamps don't use a high voltage pulse igniter, unlike high pressure sodium or metal halide, which need an initial pulse of about 4,000 volts to get them going, so I would think it *might* be possible to do it. However I don't know how the autotransformer style ballasts that US spec HID lanterns have would do running these lamps as they have quite a high open-circuit voltage (OCV) to get that initial startup on the probe in the arc tube. You would have to grab a meter and measure a mercury fixture without a lamp in it and see how high that initial voltage is to work out if it'll run an LED that way, although I'd still advise against it, as you can have issues when switching on and off where the ballast produces a high voltage spike due to how electromagnetic ballasts (which is what a mercury lamp uses) operate. This can easily kill an LED lamp in as little time as it takes to click your fingers.
that 250w mv is deff going to be brighter than the led, 2x brighter.. The LED seems brighter due to the intense glare pin point light the diodes have. The CRI should be near the same the LED might be a little higher, but light output on the led is most likely around 5,000 lumens, maybe slightly more. Thats also assuming its actually 54 watts, remember 99% of the led lights out there will claim say 40 watts or 60 watts or 100 watts but they arent, ive tested lots of these lights and they are usually 50% of what they claim. That 250w mercury vapor bulb will output near 12-13k lumens, which is 2x brighter than the LED. The LED also has multiple dark spots with all those spaces, the bulb is 360 degree coverage, also garuntee a MV bulb and ballast will last 5+ years, and the ballast probably 20-30-40+ years. Those corn cob lights are nortiously poorly made. I honestly would have gone to metal halide but thats just me.. You get the white light, and less power usage and more lumens
Five years?! My MV garden light has been going straight for over a decade. I find most LED's fail sooner than the old incandescents they replace. I'm starting to avoid LED at all costs now - Stick with discharge and incandescent.
@@dancoulson6579 running 10 years+ and getting 10+ years of practical use is a diff thing.. your bulb at 10+ years is running at 30% or so if its nornal brightness you just dont notice it because youre used to it as it slowely got dimmer. They lose lumen/lux output as they age i garruntee you. They also shift color spectrum the new clear bulbs go from blue/green to more of just a green color. And the coated bulbs also lose spectrum as the coating wears out. And they still use the same amount of power. This is why its good practice to change your HID and florescent bulbs out after a few years.
Mercury vapor/metal halide ballasts are nowhere near $250 and bulbs are nowhere near $30. More like $40 for the ballast and $15 for the bulb. Probably cheaper if you're buying several at a time. FYI you can use probe start metal halide ballasts for mercury vapor bulbs.

@Demon-Slayer1983 I just bought a 14,500 lumens and it doesn't work for some reason that's why I was using RUclips lol .. but I seen those at Home Depot while I was looking for bulbs
@sopamarucha2388 the driver/ballast may be wrong. I was told by an electrician that is a possibility that may need to be changed to work with the bulb.
UHH no you are making the wattage lower.Replacing with these LEDS will save you more on cost of photocells. photocells can handle a lot of watts .So by lowering the watt draw/amp draw you will have to replace the photocells less.Thanks for watching .
Maybe the hole ballast and bulb cost 300 but that 250 watt bulb was not 300 plus you got to have that ballast for the corn bulb so how much was the hps bulb vs corn led just the lights no ballast you will make your money up on it in like 2 to 3 years I do like that bulb definitely not downing anythang inless you got a special build ill look back iv used them before can you make a video showing after you changed the light if you say it's way brighter I'll believe you cause you been working with the high pressure bulb so if it's brighter you let us no but the hole point is its supposed to be Brighter right . You have a good season.

Nope, I think I’ll just keep on rocking with my good ole reliable Mercury Vapor lights. So much better than these crappy LEDs!!
Is the a cermaic socket like a regular light that a person can by to put the 39 ae size in?
Is it of equal lumens? Does it need to be to be an equal light?
In My opinion The led bulb is brighter and no it does,nt need to be the same watts or lumens.
250w mercury vapor lamps like that sylvania output 160,000 lumens an LED bulb outputs 30,000 lumens at best. you say it is brighter because the bulb is daylight which gives the optical illusion of the bulb being brighter
@@khalidhebshi5318 wayy off, the 250w mercury vapor puts out about 12-13,000 lumens, the led if its truely a 54w.. might put out 4-6k lumens.. MAYBE
And another thing. Your hand would fry when you touch the old light bulb.
Could you describe the color of the LED bulb to that of a Hg Vapor? Would you say the color temp and/or hue is about the same?
When comparing led to HG compressed Mercury the colors are pretty much the same but the HG as it degrades over time starts getting a greenish tint to the color Plus the LED bulb does not need a ballast it's built into it also to further note compressed HG bulbs are just about the same price as an LED bulb but we've had HG bulbs on this property for 5 to 7 years but the light output on the LED bulbs is basically I would say brighter then the HG bulbs

What is the bulb size on the screw end; so I can make sure to get the right one instead of a regular house bulb size?
E39 I believe
They sell a insert that goes in the old fixture so u can use the small led corn row bulbs , almost half the price of the big bulb and still bright .
