yep it color shifted and lost some lumens.

May all the great lighting technologies have their place in history.

Nice that they still have the 8-footers there!

Not uncommon for LEDs to dim .. but change color too? LOL what junk

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

What a bunch of garbage! I like LED's only as indicator lamps, not general lighting.

Preheat and T-12 fluorescents forever! Down with LED's and instant start T-8 fluorescents.

Love that they still use T12 @ Walmart! I was image that if they not ever making F32T8, will Walmart run F96T12 at Supercenter Walmart?

Say NO to ban at Incandescent light bulbs!

Loving the 8 footers! This lighting setup (the t12s) was the standard for Walmart up into the mid to late 90s, or whenever they started switching over to the supercenter format. Interesting that they went to the trouble to install those LED tracks but haven't bothered to maintain the existing lighting. Yes LEDs do last a long time, unfortunately the circuitry that drives them is often crap.

I agree with Jercar954. LEDs are great for indicator lights but not general lighting. They are AWESOME for trailer and flatbed truck lighting too. I remember an old Wal-Mart that had all T12 8 foots, but it was abandoned in favor of a new "super" store back in the early '00s and that was the last time I set foot in one of their stores.

The only good led bulbs are Phillips, most others just don't last for general lighting
For indicator lights they are great!!

Walmmart here was originally installed here with the T8 dimming system with many many ballast failures!

LEDs are also great for stage/DJ lighting because of their intense, vivid colors, low power consumption/heat output and ability to have one fixture produce many colors via RGB mixing. But I agree for general lighting they just haven't quite gotten there.

@Peach_Lover, absolutely! I forgot to mention that, even though I have 30 LED PAR cans made by American DJ and Chauvet. They are BEAUTIFUL for color mixing and have very vivid colors. I have had almost no trouble with any of mine, with the exception of a bad DMX board on one Chauvet unit.

CREE should be spelled C-R-A-P! That name just pisses me off to no end. Just subsidized rich people shoving CRAP--yup the name fits! Up our bums! The world is going to be a REALLY DARK place in 10 more years---in 2015, we now have a proliferation of these CREE UGLY fixtures in our parking lots here, and get this--they have adjustable knuckles because CREE claims they can be used for BOTH downlighting like shoe box fixtures, AND for "flood" lighting---they can't even project enough light to the ground at a 25-30 foot height straight down, how do the retards at CREE expect these hunks of ugly junk to project light a hundred feet horizontally or more? YEAH RIGHT! Erase your "computer models" and get a set of BRAINS---LED's have NO--yes ZERO optics! And reflectors are worthless behind them. There is am Ocean State Job Lot store in our area that has these pieces of crap in the parking lot, and 3 on the roof as floods---and the ones on the poles are about 15 feet high, and can't put enough light on the pavement to even know they are on, and the ones set up as "floods" project NO and I mean NO noticeable light at ALL! They are awesome GLARE BOMBS though! They are a poster child case of "apparent light" versus "usable light". In other words, look up at them and they "apparently" look REALLY intensely bright, look DOWN at the ground and there is about 0.0000000000001 Foot Candles on the ground! I mean, this lot gets more light through the front windows from the T-8 fluorescent lighting the store, than the CREE junk actually puts in the lot---and alot of people are complaining about how dark the lot is. They will lose customers afraid to go there at night due to poor lighting, and this store will go out of business, Way yo go, RETARDS at CREE! And they are new, not even dimmed out yet--wait another year when they are 25% dimmer than now---they might as well cut the power to them and go with NO lights in the lot, as they will be only for decoration anyway. And they are too darned UGLY to be decorations! To think, these replaced perfectly working Westinghouse MV OV-50 units that USED to light the lot well, with 400 watt MH floods where the CREE junk has "infected" on the roof! The "disease" is spreading faster than the plague, and places they infect will never be the same again---I need to get a good air rifle to shoot this ugly junk out! Rick D. New slogan for CREE: "At CREE, we hire DIM-WITS to design and build our famous DIM LED's--bend over, folks, and grit your teeth while we insert them where the sun don't shine and where NO CREE LED will ever be bright enough to light up, either!"

I don't absolutely hate led's, I just think that with china making all the stuff, they shouldn't be used for general lighting. If they were made in USA and were properly designed with good optics (or even made in china but good quality), I would be happy to use them. I have a cheapo LED nightlight in my chicken coop that has been going for 1.5 years 24/7 and has started flickering a tiny bit a few months ago. It has been in very high summer heat, so that is probably a contributor.

UPDATE! The T12 recessed strips have since been group relamped and the dead ballasts replaced with electronic T12 ballasts. Still maintained. The CREE junk here are still there, greener and dimmer than ever.

May all the great lighting technologies have their place in history.

Good to know they are still maintaining the T12s.

A few months ago, i saw about 10 of these things in a bin at a junkyard.

Old lighting is, and will always be, the best lighting.
