FYI: "Lights of America" LED bulbs -- Costco refunding purchase price


We got a letter from Costco today inviting us to return the "Lights of America" LED bulbs we had purchased because they do not live up to the claimed life of 20K hours. Four different SKUs are listed.
Sam's Club has sold some of these as well, but no communication so far from them.

I got a few at Ace, on my tests they are junk, low output, not what is advertised and a poor grey color. I am returning mine. Months ago I looked at LOA and could not find they even offered these leds.

It's difficult to compare light output because different incandescent bulbs of the same wattage vary according to their design -- e.g., long life vs. high output.
I am not dissatisfied with the light output of the "45W-equivalent" ones I bought at Sam's. These are the ones with the LEDs arranged in a convex conical shape. I couldn't tell any significant difference in output from the 50W incandescent reflector bulbs they replaced. The light is a little bluer than those incandescents, but that does not bother me.
The R30 style also seem to be OK wrt output, and the color is similar. BUT one of the three I bought has died already: it started flashing one half of the individual LEDs, then seemed to recover, then died totally.
The single PAR38 I bought produces light of a somewhat warmer color, having a mixture of bluish and yellowish LEDs.
Menard's has FEIT LED bulbs, but only of low power -- 1 to 1.5 Watts. I can't find LED bulbs by Sylvania or GE.

The LOA brand was one of the first to have the compact fluorescents and every damn one I got was junk, so the shock that the LED are junk too doesn't really surprise me.

Agreed that the LOA *fixtures* were bad news, but an independent evaluation a few years ago rated their CFL *bulbs* as better than Sylvania.

They must have changed bigtime a few years ago then, or started getting their bulbs from a contract manufacturer who knew how to make them (and probably also sells to others).
My experience with LOA CFL bulbs has been the worst there is except for dollar store stool specimens. I only bought one LOA CFL since 2001-2002, and that was one I got in 2005, with ratings that I consider wrong. (Comparing to a 60 watt incandescent that lasts 750 hours, when 60-watters are normally rated to last 1,000 hours, and claiming 1048 lumens when producing no more light than others producing 850 lumens, and claiming electricity savings based on 16 cents per KWH at a time when few paid 16 cents per KWH.)
Ones that I got in 2001-2002 and before had a high rate of dying young, and almost universally fell short of claimed light output. One model I tried had a light output claim in lumens later revised downward, but its light output claim in incandescent equivalence remained exaggerated.
I mention more of my experience with speficic CFL brands/models in:

They are *SO* bad that I have to repair one or two literally every week. As I'm writing this, two out of four are dark, I just did not have time to work on them yet. Irony: they are lighting my electronics workbench and so I just bring them down without even getting up from the chair and reach for a replacement white LED and 3 minutes later it's going back up and works until another one of the original LEDs gives out.
Thankfully (in terms of repair, not use of course), they are *SO* bad that even glue that holds the socket prongs body to the transparent cover crumbles (!) right after you drive a knife into the crack between the two parts and give it a slightest twist.
I have a little rig devised specifically to test the LEDs in the LOA fixture but sometimes you can just see a dark spot inside the LED that indicates a burnout.
There are 24 LEDs in each light and I estimate that after 18 months of use/repair cycle there will finally be no original LEDs left. I don't know if it will increase time between failures too much though because the whole idea of powering a string of serially connected LEDs from 120V seems faulty to me - each (good) LED does have a 40,000 hours lifespan or so but having 24 of them in series, you'll have to stack the MTBF up (calculating MTBF properly is not my cup of tea) and for the whole fixture it will be a small fraction of what the single LED would last. My next LED light will definitely be a 12V parallel - connected LED type.
Anyways, sorry for the long rant, these lights have been an eyesore for the past year for me, I can't wait to use the earliest opportunity to get rid of them.
If you are not able to easily repair them yourself, there is no question about it - return them ASAP. byt the way, Wallmart still sells them ...

We haven't had any as long as a year yet, but so far the only one giving trouble is one of three R30 bulbs that normally are on for several hours every day. These are bulbs with a regular ES base; we use them in our track-light setup.

in part:

Most LED failures do not affect their conductivity. The usual reason for an LED to be considered "failed" is for it to have faded excessively from number of operating hours (or combination of number of operating hours and temperature).
I am aware of LEDs failing open, but that is usually either from severe abuse or from the LEDs being cheap rubbish, with thermal cycling (generally with repeated very large change in temperature) being in a distant third place.
