cree led lighting: cr6 vs cr4 vs lr6
We are in the early framing stage of a new construction and are trying to determine the lighting for the house. Live in CA - we do need to adhere to Title 24. So, edison type connectors are out.
Hate CFL and are leaning towards LED based lighting for the entire house ( or at least key areas such as Kitchen/FR, LR, DR).
Among the options available, it looks like Cree ( Ecosmart) LED are the best fit ( need dimmers, like warmer 2700K) and seems to be generally liked by GW members as well.
We are deciding between 4" (CR4) and 6" (CR6 and LR6) options (CR4=575 Lumen, CR6=800L and LR6=1000Lumen). There differences between CR and LR don't seem to be meaningful ( LR obviously has better efficiency and lifetime but I do think the price drop over next few years trumps these factors)
Couple of questions:
1. In Norcal ( South Bay ), any idea what a typical install cost for the light ?
2. A quick back of the envelope computation shows that CR6 is likely the most economical option among the three ? Am I on the right track ?
3. Any other factor to consider ?
