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.

I have better lighting now with the LED recessed. In the adjacent room, the 55 watt 2D surface mount fluorescent fixture was replaced as the space was enlarged and replaced with 5 LR6 lamps (10.5 watts). The space is now better lit than before and the power consumption is less especially since the lights are slightly dimmed. The light output is 2700k which is just like a traditional incandescent light. The 6" cans and lamps are cheaper than the 4" cans + LR4. The Cree xR6 ( where x == L :: x == C) do not require any trim ring. The CR6 is dimmable to ~5%. You should be able to look at the lights at Home Depot (CR6) or Lamps Plus. There may be flickering if the dimmer is not matched to the load. ie - the load is too small to be dimmed. For instance the Leviton Vizia RF+ has a min load of 40W which makes it unusable with just 1 or 2 LR6 lamps (total load for 2 - 21 watts). Lutron dimmers seem to be better than Leviton.

My problem is that I would like my lumens to be at least 800 for my home office as I like a lot of light when I am working now since I turned 51 this year. My eyes need more light. The 800 lumen's Cree are so expensive but Davidtay indicates that bulbs inside a can lose lumen's as the heat gets trapped so the retrofit is the way to go. My other problem is I just prefer 3,000K lighting than 2,700K lighting for effect in the room on color and how it makes me feel. The BR30 and BR40 will be great for general lighting in the LED Cree but I have a feeling it will not give great lighting on my desk and I may want a Par38 in a 6" can. Please correct me if I am wrong.

Lots of threads on this already. My permits were pulled before the latest Title 24 became effective, so I may not be totally up to date. Wherever you can still install Edison sockets, by also installing dimmers, you should do that. Cost will be lower, and options down the line will be easier. Cannot do that for the kitchen. You may still be able to use Edison in the bath, if it is on a vacancy switch. I wish that I had spent the extra money to put in CR4 instead of CR6 in my living room. They just look better, and I didn't have anywhere in the LR that needed 800 lumens. I probably put too many CR6 lights in my LR/DR. I should have planned on supplementing with some nice reading lamps. I can't remember what I paid for installation (San Jose), but my guy is quite reasonable for add-ons. He had quoted base on 6 cans in the LR/DR, I put 21 plus cove lighting. The LR6 doesn't dim much, and is expensive. Sconces. Plan some lovely sconces. I lost a few in my remodel, and regret that.
