Cree CR6 flicker-NOT on a dimmer
I am hoping to find out why I have had so much trouble with my Cree CR6 LED's. Way back in in the beginning of my kitchen remodel I lurked a lot on this forum to figure out what I wanted in lighting. I knew that I didn't want a yellowish light on my bright white cabinets, so I orders a few different temps from Polar Ray, 3000K, 3500K, and 4000K. This are the actual Cree product that is 625l, GU24 base as I'm in CA. I decided on the middle one as fitting my needs. So my contractor ordered the rest of what I needed from my local electrical distributor for the entire ground floor as well as stairway and upstairs hallway. I did actually see the boxes of lights when they came in and they were the right thing.
I repositioned the ones I had bought from Polar Ray in other areas such as laundry that weren't getting remodeled.
Well, before the big order came in I was experiencing substantial flicker on all three of my Cree lights. I sent them back to Polar Ray and they assured me that this was highly unusual for actual Cree lights, especially as they were not on dimmers! They were kind enough to exchange them for all 3500K since that was the color I had chosen.
Well I thought that resolved it but now I have had several more start to flicker and my contractor seems unwilling to get to the root of the problem. Some of them are in areas that have a dimmer and some are not. We talked extensively about the dimmers and he knows the difference between the ones for incandescent and LED. However, I did not see the boxes for these. He is of the mindset that these lights are not what they are cracked up to be and wants to put in Ecosmarts from HD at 2700K so he can be done with it. I am heartbroken because I feel that I researched so much about all the little aspects of the remodel and these were supposed to be the best money can buy.
The other problem is since this is the third time I have had him come out for flickering and as a result the lights have been rearranged and I no longer know which ones were the ones from Polar Ray and quick ones were from the local shop. He temporarily put in Ecosmarts so I wouldn't have to deal with the flickering or a empty hole and he repositioned them to be al in one room.
He is coming out to trouble shoot next week but I am not too confident in a resolution that does not involve a trip to big orange.
What could the possible reasons be, and what should I do? Also, assuming the problem is something he can fix and the lights are not bad, is there any reduction in lifespan or quality of the light that has been subjected to a lot of flickering? Or should I insist they all be replaced to new anyway?
Thanks so much!
