We are also Lutron with our LEDs. What I'd say is, if your electrician insists, let him use them with a written contract that if they don't work, he replaces them all on his dime and time.

I just looked up online about cree lights flickering. I have lived in my current house (11,000 sq feet over3 floors) since 2014. The house is a very faithful colonial reproduction from 1980. My wife and I did a thorough redo of the electrics, mechanicals, Windows, new cedar roof and cedar siding (where needed), paint, bathrooms... We had the entire house rewired and had had about 150 recessed lights in the house (bedroom, kitchen, all bedrooms, all closets, sun room, pantry, halls, laundry room all basement rooms) Redone in Cree 2700k BR30 65 watt bulbs (from reputable electrician). I did this because our past house (3200 sq foot over 4 floor) had many rooms with similar recessed lights I converted to Cree led (the exact same) in 2012. The lights in the old house DID NOT flicker when lights were at full brightness, but the old dimmers were a problem. So I went to Lutron dimmers for CFL and LED. There were no more issues. Well, due to this experience, all lights in new house started up on these led comparable dimmers. I have to be honest - I am SUPER DISAPPOINTED with CREE. I have had at least 20-30 Cree flickering lights in my house. At first I thought it was the rooms, because certain rooms flickered all the time - but, those rooms had a ton of lights. I have replaced them with the LOWES equivalent and have not had an issue. My office (family owned) converted over as well and my parents did. And we all did Cree. We ALL had flicker issues. Some are so bad, they go off for a while! When we switched over to the Lowes brand (only on flickering lights), no more problem. The strange thing is that the Cree completely integrated low profile units (not screw in, but lower profile lights we needed in our pantry that look the same once installed, but are half the installed depth) have all been great. I am almost certain it's a quality control issue. People who have old incandescent "high watt" dimmers - realize you are replacing old bulbs with new ones that demand 1/6 or less the power. The old dimmers don't control the low load properly and you will get flicker if you dim lights. But if you have led ready dimmers or a solid switch, and lights flicker... It's the bulb. I've tried everything and it was the bulb. The Cree's are supposedly the best - but I have had a problem with at least 30. Replacing them fixed issue and other cree's in same circuit and switch have been fine for a couple years. If you have similar issues and a good dimmer - it is not you or your house. It is the light bulb. Return it. I think the Cree's made in the past had better quality control. I asked homeowners of my past house if they ever had to replace one (they are all from 2011/12 - all Cree) and they say they are great.

Well, we decided to give it a try. We put in the only thing we could find in stock at Lowe's that was on the Cree list of compatible dimmers - the Lutron Diva DVW-600PH. The Cree list says it's good for 1-7 fixtures, but with our 2 we are seeing a subtle flicker at 100% on the dimmer, and a pronounced flicker at anything less. Like people have mentioned, there isn't a huge difference in brightness across the range of the dimmer. I also know that 100% on the dimmer is not 100% of what the fixture can put out, and I would like them to be brighter. They are okay at 100% on the dimmer but I do think I'm sacrificing some brightness and I'd like to get it back. Therefore, I'm going to ask them to take the dimmer out tomorrow. Just thought I'd pass along our experiences. Other than the ineffectual dimmer/flickering issue, I do like the fixtures. The light color is nice and the fixtures themselves are very streamlined and sleek.

Good point. Cree has taken care of that with their 'color management' system. They first tune the light before it ships. After, the fixture actually continually measures the color of the light output. If it shifts for any reason, it will automatically adjust the LEDs within to get it back to the original light output. You can see in the LRP-38 a small hole in the center of the reflector. That hole is the sensor. And you can actually manually initiate the change to prove it. I've taken a white piece of paper and slowly moved it closer to an LR-24. The white paper causes more of a reflection back towards the sensor. In response, the light actually starts shifting to a pinkish glow. Take away the paper and it goes back to the normal output. So with any of the CREE products, the color output will stay the same for the life of the fixture.
