We bought a four pack of these bulbs. we got the at the end of april 2017 and they BOTH just burned out! They look nice and work great in our tiffany lamp. They do not even get used every day. What a rip off! led. I thought they were supposed to last a long time. thumbs down! Never buy again!

I bought this to use in the boat on weekends.  The burner on this burned out very quickly, within 15-20 uses.  Disappointed.

When lit these lights are nice. But mine burned out in less than 3 days. Based upon Amazon recommedation I ordered additional CR2032 batteries. I found it impossible to open the plastic battery pack to change the batteries (each light string requires 2) and no instructions were included.  I would be willing to revise my review if the manufacturer or a more highly advanced buyer can advise me. As it is I don't have time to dither with it two days before Christmas...

After buying our 2nd unit which burned out after only 5 months (with a 30 day return policy) we are going to look a different direction.  You may want to keep looking too.

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.

One burned out after less than an hour's use. Obviously defective product. Now Amazon is not wanting to refund my money because it's beyond 30 days. I'd never buy these again.

I purchased 2 of these 75 Watt replacement LED bulbs from Amazon, made by Cree
in April 2015.  The first one burned out in December 2015, and I thought it mist have been a fluke!
The second one burned out March 7, 2016.
They did not do very well for bulbs that claimed to have a 22 year life!!!
VERY disappointed, and will probably never buy Cree bulbs again.

This product burnt out in record time, less than 3 months. They are beautiful when they work, but just didn't last!

We purchased this unit for $100 more then the smaller units thinking we didn't want the cheap one. Unfortunately after only 6 weeks, using it 2 hours on the weekend it has already burned out. We have not been able to contact the seller to get it replaced.

Disappointing product to say the least:(

This bulb burnt out after less than 36 hours of use. I was testing it before getting my baby bearded dragon and it burnt out on my dragon within the first 24 hours of having her. Iv'e already purchased a new UVB bulb from a different brand. I'm not risking it with these again. My beardy needs her precious UVB.

It failed after 30 days of actual usage. The power to the lights stayed on even in the off or auto position.
