I just thought I would chime in about the new Cree CR6 as compared to the Cree LR6. My name is Bryan Alu and my company polar-Ray.com , based in Boulder Colorado. As one of Cree's largest dealers, I have direct access to the latest info about Cree products.
For starters, just a minor correction to jginnane's post up above. The post says he/she purchased 4 CR6C down lights. I am sure that he/she meant to say that he/she purchased 4 LR6C down lights. The CR6 will not be available until sometime later this year. Cree won't pin down a date yet and there are only a handful of prototypes floating around that are being shown to dealers at this stage of the game.
There are some salient differences between the current LR6 series and the upcoming CR6. If you love the 3500K LR6C (C designates "cool") then you will be disappointed to learn that the CR6 will only be available in 2700K when it comes out and I've been told that there is no plan to add a 3500K at this time. As was announced by Cree the CR6 will have a retail price of around $60. It will be available at certain retail outlets ... so if you buy it locally add $4 or so for sales tax. That compares to the current online price of $79.95 with free shipping and no tax ( polar-ray.com) for the LR6 and LR6C.
To make the new CR6 less expensive Cree removed some performance and options when compared to the LR6 . Due to a much smaller heat sink, the CR6 is rated to last 30k hours as compared to the 50K hour LR6. The CR6 will not be as bright either. It is rated at 575 lumens vs 650 for the LR6. That's probably going to mean Cree will make a claim that it is just shy of a 60W incandescent as compared to the current claim of 65W for the LR6 which I think is at least 10% on the conservative side. No big deal but, in spite of its reduced brightness the CR6 is a 12W light and Cree recently reduced the LR6 spec down to 10.5W. The LR6 has optional trim rings available and a really well designed eyeball model. These options are not going to be available for the CR6.
Bottom line: The CR6 could be thought of as the CREE LITE ! It will be a nice addition to Cree's product line but the current LR6 or LR6C may well be worth the $16 dollar premium ... and it's available today. On the bright side, Cree has just released a 1000 lumen 6' recessed light called the DR1000. We should have them in stock in a couple of weeks. I can't wait to light it up. The increased lumens will solve some issues related to ceiling heights over 10 feet.
