Lasted three times then one side of the leds burnt out. Opened it up and found not enough thermal paste on  back of led. Tried it again and the other side burnt out. So mad i threw it out.
 My whole reason of switching was  because i was tired of replacing those fragile halogen bulbs.  Dont buy.

I installed three of these two years and two months ago, and two of them have already burned out.  They ran at night, so on average about 12 hours per day.  I've never had LEDs with such a short lifespan--even the early ones did better.

I bought 2 of these for my fish tank to run from 11pm to 2am on a timer. When I first put these in, they were great, but after running them every night for a few months, one unit had an LED go out and the other unit had the same shortly after. So now I only have 4 of the 6 LEDs working at night. It can't just be my setup because the white LED panels (another brand) I have running from 6:30a to 11pm for the same time period and none of them have burned out.

If all the LEDs worked for more than a few months, these would be great. Otherwise be ready to replace or find another brand.

About a year ago I bought 3 Cree 100-watt replacement LED bulb one just went dead, so failure rate for me is at 33%, the other two seem to be just fine... It's disappointing that you spend 20 dollars on light bulb and last less than a 8 dollar CFL.

Bought three of these because they had good reviews despite being fairly pricey.  After 5 months, one was flickering and had to be removed from the lamp.  Electrical tape inside the base was melted from heat or some sort of electrical short and it had a "burned electrical wire" smell about it.  Not good.

Edit: Less than a month later, and the 2nd light has failed in the exact same manner as the first.  Bulb flickers, and components in base smell like burnt electrical wires.  This is 2/3 bulbs now that have not lasted as long as a $1 bulb.

Final edit:  Annnnd, now on 1/14/15 third bulb of three has failed.  So, all three bulbs failed within 6 months.  On the plus side, at least I am finally done with these dissapointments.

I have bought this product 3 times now and its great because of the side mounted LED. Unfortunately this is the last time I'll buy it for an external automotive application. After replacing the strips twice on my wife's car its just not worth it to do each year. It may be due to the weather conditions  but the first pair had a section that went out on one side. The second pair had a stand that faded and wasn't as bright LED white as the other. These are great lights and I have a stand in the trunk that has been working for quite some time and very bright.

One bulb was DOA.  I contacted the seller - they asked if I wanted a replacement. I said yes and never heard from them again.  The second bulb lasted about a month.  The third bulb still works.  I have a number of led lights in my house. This is the first time I've ever had a problem.

I ordered 3 of these. One died within a month of normal use, one died in two months and the third has been fine. They're not in parallel so your lights will stop working as soon as one led blows or the thin single strand copper wire corrodes or breaks.

Thete are suppose to last at least 25000hrs and they are not performing to your advertising

Have had  these just over a year; I use them under cabinet to shine down on my desk.  After about 8 months, one burnt out - it started intermittently turning on and off to the point of high annoyance, all three LED's, so it must be the electronics, not the bulb.  Then a second of the five did it as well.  Unplugged them, tried to plug them in after a day or two, still same way.  I just noticed that it says there is a manufacturer's three year warranty, so will give that a try.  Lighting quality is good.

I think all the people who left good reviews must have done so right after purchase.

They didn't last very long at. One of them went out completely after a few months and the other just dimly flickers.

I recommend trying something else. LEDs are supposed to last forever.

I installed these lights on my deck (Ohio) in October, and out of the three stings of blue lights purchased, one burned out completely and on the other two only about 6 individual LEDs still lit... AFTER ONLY THREE MONTHS!!! On the other hand, the string of white lights (the same brand) which was connected on the same string as the blue, continue to burn without a single failure... 18 months after installation.

Not sure why the blue would be different... I assume just the exterior tubing is colored and the guts are the same, but that's my experience

I purchased 7 of these LED bulbs three years ago. One has just failed. The manufacturer claims that the bulbs will last for "4 years of continueous (sic) use."  My bulb have typical kitchen use, which is far less than continuous use. I'm looking for a different manufacturer.

Bought two of these about a year ago. Put one in, and the Blue LED is already dead. Each bulb has three LEDs - Red, Green and Blue - to create myriad of colors and intensity. Good for occasional use. Does not appear to be durable enough for daily use. The other bulb has not seen much use, has been lying on shelf. The brightness when all three LEDs light up is not even equivalent to 25 watt incandescent. It is fun to play with the colors for a while - once in a while.

May have to add more heat sink compound to back of  led(as mentioned in other reviews) . One died in 3 months(no compound) others modified and still work great).cheap price

This is my 3 order and I have about 9 of these now. The first 2 orders were perfect, but the last one I got this week was terrible . The sticker fires not stick and leds came off with in 6 hours ... I'm. It sure what they changed but this is not 3M standard .
