View Full Version : LED light bulbs from Lights Of America

I recently bought some LED light bulbs, made by Lights Of America, at our local Ace hardware store. Lights of America part number is 2026LED-30k and 2026LED-65k.

So here are some of the claims written on the packaging:

Uses 1.5W
Replaces 40W bulb
90% more efficient than incandescent and halogen bulbs

NOT on the package:
Lumens rating

Also missing: any mention of this product at their website.

Okay, for starters, when I got home and tried them out, they definitely do NOT look as bright as a 40W incandescent bulb.

Secondly, they're efficiency and power claims on the package are inconsistent with one another. 1.5W vs. 40W would mean 25 to 30 times more efficient, not 90% more.

Finally, similar bulbs by Philips indicate these 1.5W bulbs are closer to the light output of a 10W incandescent. (Philips has 1W LED = 7W incandescent, and 3W LED = 20W incandescent) That's still an impressive 6 to 7 times the efficiency.

I imagine they thought people would be put off by a 10W equivalence claim, since that is not a commonly used wattage. And to make a truly 40W equivalence would require 4 times the number of LED's. They are already charging $9 or $10, so perhaps they don't think they would sell if they had to charge more.

i've never had much luck with LoA products. the fluorescent screw-in bulbs i've bought failed quickly. naturally, this erodes my confidence in the idea that one can save either energy or money with them. i believe i ended up wasting both.

i do think LEDs will eventually be the way to go, but i still wouldn't buy from LoA.

I hate to say this but the product looks like it lives up to half its claims. It doesn't make any claims as to a luminosity replacement it just says replaces a 40W with a 1.5W. They meant that it will fit, not be as bright. The wording is purposely vague so people will assume it will be as bright. Most people won't realize that there is no way an LED using 1.5W can be even close to as bright as a 40W incandescent, that would be about 2600% more efficient wouldn't it? The 90% more efficient claim would take some some creative defense but I think a lawyer could do it.

A lumen is roughly the power in the visible band
A 40W light bulb puts out about 2% of the energy in the visible (about 12 lm/W = 500 lm)
For a 1.5W (perfectly electrically efficent ) source to match a 40W bulb it would need to achieve around 330 lm/w

A perfect source monchromatic source in the middle of the visible is 680 lm/W - no broadband source is going to manage 500 lm from 1.5W, a green laser diode might, but only because of the definition of a lumen.

I can't comment specifically on the output light claim, but...

You're not completing the math, so it isn't clear to me that you have it right. 40/1.5= 26.7. That's 26.7 times less power. That's not in terms of efficiency or "more efficient" - it's upside-down. In terms of efficiency, that's 1/26.7 = .0375 = 3.75% as much power or 1-3.75%=96.25% more efficient.

But since the claim is 90% more efficient, not 96%, then it should put out 1.5/.1=15 Watts of light (equivalent). Seems an odd claim to me - not technically false if that's what it really puts out, but definitely misleading since the words imply something different than the numbers say.

Well, that makes more sense. And if the light output is 15W-equivalent, that's comparable to the Philips numbers.

they are using a bit of deception here. i bought some too and was similarly disappointed. i had previously gotten some LofA bulbs at Costco (floodlight bulbs) and was reasonable satisfied though the light is more directional than i wanted.

i then bought some of these, same ones you have, off the internet and was questioning them much like you. their words are deceptive. after searching a bit on the internet i found out these bulbs put out the equivalent to a 25W bulb... but they say to replace your 40w bulb with them. I am not totally up on whats available from lightbulb manuf but i don't think 25W bulbs are common so you would use these to REPLACE a 40W light bulb instead of a 25W bulb. anyway, the improvement in efficiency is reduced considerebly to NEAR the 90%.

also, the color of the light is dependent upon the "color temperature" f the bulb. the ones i got are 30K. they make another one of the same type at 65K. the 65 K would be MUCH whiter than the 30K.

personally, i don't think i would buy more of LofA bulbs. I've had many early failures of the CFLs and am greatly dsappointed. of course, to take them up on their warranty you have to have the receipt to show when you bought it.

nonetheless, i have put these bulbs in porch lights and the refrigerator. besides using LESS energy than standard appliance bulbs, they will not dissipate as much heat into the frig so that will help with the operation of the frig.

you will find equivalent CFL lumen output to be a dimmer quality of light. this is because of the color temp being diferent. the good CFLs with high color temps tend to be MUCH higher in cost than the cheaper ones (that are so prevalent today) that neither provide a good light OR the life that they claim.

When it comes to lumens for LEDs, most manufacturers claim about double what their LED actually puts out.

I purchased 6 of the 2025LEDE12-30K1.5 watt 30ma lights for a hallway. The light output is nowhere near 40 watts as claimed and 10 watts would be a strech. That said they did produce enough light for the area. The big problem is the 50% failure rate in 60 days that rates these lights a big expensive zero!

Try aiming them up onto a white ceiling. LED lights are extremely directional, much more directional and focused than even very focused and directional incandescent, halogen, etc light. If they are pointed upward to a white ceiling, they will seem about 10x brighter and they will light up the entire room (or at least part of the room). We have 9 of these in our main room and our energy bill is more than 20% less for the entire house, because these LED lights use a small fraction of the energy of regular lights and moreover because in the summer, this gain is at least twofold because the A/C has much less to cool off since these bulbs produce much less heat, as well.
