What does Cree have against 5'' cans?
There's no CR5. The BR30 LED floodlamps that are available all have some issue (poor color rendering, slow startup, not wide enough beam, or too expensive). But lots of retrofits I run into need 5" modules (with built-in trim) or BR30s if you keep the existing trim bezel. The Home Depot 5/6" modules made by Halo IIRC aren't too bad, but I'd prefer 2700K rather than 3000k, better color rendering, and a deeper, less glaring lamp. The excellent Cree modules are 4" or 6" only, and their LBR-30 50-degree floodlamp bulb is 2700K and has great color (94 CRI) but is expensive and wider than PAR30 bulbs normally are and don't always fit, and only dim to 20%.
Is there a good 5" recessed LED out there?
