How does the wattage draw of these bulbs compare to that of the standard florescent bulbs they replaced?

We love these LED bulbs and have 8 of them in our motorhome. But when I measured the amp draw, it was not much less than the T8 florescent bulbs they replaced, and the backside still got warm. But the light output is much greater & whiter than the fluorescents they replaced, and they are a well made bulb. I think to get the brighter light, the many LED's are 'pushed' which accounts for the amps not being as low as other LED lights that have fewer LED's. The back side is a heat sink so that is why it is warm.

I don't know. But I put installed the lights in my front flower beds a year ago, and last evening as I was walking up my walk, I was again amazed at how much light they put out for the piddly amount of wattage they use. I wouldn't have believed it.

I simply replaced almost identical fixtures already in my yard. Spacing is on the order of 10-15' between them in my small yard. If I recall correctly bulbs are up to 100W but I used CFLs so the wattage is much lower. They accept bulbs with a standard "Edison Screw" base which I believe in the US is E26.

LED bulbs are more energy efficient than halogen bulbs, and they definitely don't produce the heat that halogen bulbs do. I just purchased 3 of these bulbs last week to replace the halogen bulbs in our under cabinet track lights over the sink, and I love these bulbs. And I have to say that these bulbs are brighter than the bulbs I replaced. I was very impressed with these.

I have not measured it using a "actual usage" meter, but mine is a 65W and having researched it I remember other people reporting the very same thing. I am using this light for Aquarium purposes and so for me the actual wattage is not what is important...it is the actual lumens produced and the color in Kelvins that makes the difference. For my aquarium uses, I found this bulb to produce outstanding results.

I have 75 watt bulbs in mine and have had these lamps now for about a year. Love them.

I have 2 fixtures with these LEDs and another with fluorescent. The florescent comes on almost immediately, while the LEDs are a bit slower, maybe 1 second. They are much brighter & cleaner looking light than the fluorescent ones though, well worth it!

If I put higher watt bulbs in I get more light... its not like the florescent I had, really bright light. I like the "look" of the lights, I am still working on the watt bulbs to be using. Right now I have two outer higher watt, and the center less. Will probably be changing around until I get the adjustment I like. Its not a direct bright light.

They are not as bright as the 11 watt bulbs. They are brighter than either the 4 watt or 7 watt bulbs.The LED bulbs light is whiter that the standard bulbs.

Sorry I can't help you there. I just read that they take almost no power, compared to the regular bulb. I put them in two different areas of the MH and basically saw no difference in output of the lights. But I have to believe that I'm using at least 50% less power to get the same light. hope this helps.

I haven't measured Watts consumed but consider lumens lower than standard for a 65W CFL. Bulb Life is also variable and often substandard. I noticed failure if you turn one off...then on several seconds later. The bulb does however fill a niche for my needs.

We noticed an increase in the brightness of our fixtures after we replaced the halogens with the LEDs. We had been using 20W halogen bulbs. As a result, I cannot say how well they match a 40W. The fixtures run much cooler now which is a plus.

No expert here but have used in several locations.. they are smaller and work w/ a clip on shade on my small desk light.. can measure it but the say equal to 100 watt conventional bulb.. I would say equal to a 60 watt.. but do save energy so am happy with them..

the wattage that the bulb is listed at is the wattage drain your electrical system will feel, just like a house lightbulb, Wattage is not a true measure of light output it is a measure of power used. Lumens are a listing of light output. this is a 60/55 watt bulb that is the wattage it will draw

I have put these bulbs along side 40 watt incandescent, and I'd say the light output was comparable...perhaps just a tad less. 50 watt seems to be common in vanity fixtures, so you would certainly say that the output was not enough if replacing all. As I said earlier, the color is more of an issue (to me) than the output. Noticeably 'cooler' than incandescent, and not warm enough (IMO) to be called 'warm white.'

I used these lights as a retrofit for my fluorescent fixtures and I am more than pleased with them. They give off much brighter and better light than the fluorescent tubes they replaced. One of these fixtures was above the vanity and my wife has never complained about not having enough light. Our coach also has a vanity light right below this fixture (at the top of the mirror) and she never uses it because she doesn't like the light it gives off. Hope that helps.

I am know expert but they are 12 volt bulbs so the draw or what it works on is a 12 volt system, it's the Amp draw that is quite a bit less than a regular bulb. I don't know the exact amount but it's approx. 1/5 of a regular bulb. I've used them to reduce my amp draw on a circuit and worked great. Hope that helps some. Alan
