Rated for 35,000 hours, we got barely over 1000 hours before they went out.

purchased in August, 2016. installed 4 of these in my bathroom, two are already dead, and have been for awhile. Just replaced today. That bathroom light is on MAYBE 20 hours a week x 52 weeks is 1040 hours.....

We got about 1/2 hour use of it before it jammed and it no longer works.  Not a great investment for us.

While these lights did do as advertised and kept the bugs away, but they burned out in only 4 months! They have a claimed lifespan of over 20,000 hours but given I had them on for about 10 hours per day (dusk till dawn) for 4 months they lasted only 1200 hours. Incandescent bulbs have lasted WAY longer during the same use.

Bought it in December and already burned out. 10,000 hours means it should last more than a year not 4 months.

I bought the set of 10 less than  6 months ago and now I have 6 bulbs left; 4 burned out in less than 4 months. They were used as landscape lights in a water tight fixture. There was no water or moisture accumulation in any of the fixture. They were installed in Southern California where the temperature swings are not extreme either. They operated on average for 4 hours after dusk every day. That is less than 500 hours of operation before failure. Even incandescent bulbs with filaments lost much longer! I am disappointed that four of them burned out within days of each other. They flicker rapidly as they fail then they fade slowly and eventually die. I took out the bulbs and tried on different fixtures to see if the problem is with the fixture and unfortunately the blame lies with the bulb.

On the plus side, for the few hours they operated they did operate well and produced warm light casting nice shadows outdoors. I only wish they lasted at least 1/10 as long as they are advertised to last.

Great while it lasted, but it burned out in 11 months. I used it in my office which had the light on for about 14 hrs/day. 14 hrs/day * 11 mos = 4,684 hours which is just under 19% of the advertised 25,000 hour life expectancy. The life expectancy of a US citizen is about 79 years. If we lasted as long as this IKEA LED, we'd all have died just before our 15th birthday. That is not acceptable.

they didn't last long... like less then 2 months.

They advertised 30 hours of light, in reality it is less then 6 on the average.  Set in direct sunlight for over 8-10 hours and same results.

Most of them arived broken, and or broke with in a few minutes of being open. The couple that didn't break the paint wore off with in a few hours of play

We got maybe 500 hours out of this bulb.  Don't waste you time,  get a higher quality bulb if you can.

In little less than an hour I had the old parts out and the new parts in.  The longest part of the process was draining and refilling the tank.  I hope to get a few more years out of this old water heater.

75% of the product was in working condition but the lead time is such that it wouldn't have been more of a lose to send them back.

I bought 5 of these 13 months ago.  I was really pleased with the light that they put out, but 2 of the 5 failed in the last week, and a third is starting to show the same symptoms.  The power supply circuit in the base of the bulb fails causing them to start to blink and flicker intermittently.  These bulbs were used in a track-lighting system in the kitchen, probably on for an average of 3-4 hours a day.  So while the LEDs themselves may be good for the stated "20,000 hours" it turns out the unit as a whole lasts maybe 1500 hours before it fails.  Buyer beware.

They didn't last very long, but were a good buy.

I purchsed several of these, one for an immediate replacement in a fixture I had installed about 18 months ago -- far less than 4000 hours of use. The web site for this brand indicated 4000 hours (I know that the usual definition is: "from the total population, half of them are dead at 4000 hours"). So, I shall have to wait to pass judgement on the "life" of this brand, but meanwhile, function has been restored and I have an ample supply of spares.

Funny thing about Hour meters... You know exactly how long they last before they break...  Mine ran for 39.7 hrs.  Now I have to replace it with a better quality meter.
