I just finished construction of a new home with a lot of LED lighting. I used the CR6 as my budget light while installing the 'higher-end' LR6 in common areas. In total, I installed about 30 CR6 retrofit in Halo 6" cans and about 15 LR6 in the CREE can with CREE trim. I splurged the extra cost for the LR6 cans and lights in the most important rooms (library, kitchen, etc) thinking I really wanted the best there. Unfortunately, the very poor dimming curve of the LR6 in comparison to the CR6 makes me regret that decision. I can not really tell the difference in light quality between the two when they are on, but as they are turning on and off, the LR6 is much worse. I use a Vantage Controls lighting system and the dimming is terrible with the LR6 - I am looking into ripping them out and replacing with CR6 if you can believe it. In retrospect, I wish I had used the CR series everywhere - to be more specific, I used a lot of CR6's but I think the CR4's look the best. In general, it seems new construction is moving more towards the 4" form factor than the 6" and both CREEs give off the same amount of light (the LED chip appears to be the same in both models). If I were starting again (even though the CR6's are now a total bargain at ~$25 at Home Depot and the CR4's are still $50), I would do the entire house in CR4 edisons with halo 4" cans. They are a nice light that both I and my wife (who is very particular) like, the light is warm (~2800K), energy efficient, and easy to install. For What It's Worth, -Andy

The main question is whether the additional 200 lumens would be useful and worth the extra cost. If you have ceilings > 10', perhaps.

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.

Thanks for your response Davidtay. We have decided to install 6 Cree GU24 cans now and then order the CR6s when they are available, which I understand will be in late August. We decided against the LR6 based on the extra cost we would have to pay. We do not like the looks or the grease trapping potential of the ridges that show on the LR6 between the lens/glass covering the led lights and the edge of the trim. I know that you can purchase a smooth white trim to cover the ridges, however, then the total cost of the LR6 "bulb" and trim is close to $100,verses the $60 -$70 that the CR6 is supposed to cost. According to the Cree representative, the CR6 will have a smooth surface between the lens covering of the led lights and the edge of the trim.
