Home lighting geeking

[darxus]

I'm planning to replace all the bulbs in my house with something like ALZO full spectrum 5500K CRI 91 27 watt CFLs.

Are there any better options I'm missing?

I'm pretty sure I want to go with color temperature 5500 Kelvin because it seems to be the most standard in the vicinity of daylight, and, in particular, matches camera flashes.

So I'm basically looking for 5500K light bulbs with the highest CRI, color rendering index. The highest CRI is 100, matching mid-day sunlight. Worst is 0 (spiky color spectrum). I haven't found anything at 5500K over 91 CRI.

There are halogens at 100 CRI, and filtering them to 5500K might be fun.

I hate old style fluorescents: 60 CRI, cycling 60 times a second (flicker). But the new fluorescents cycle 24,000 times per second (no flicker) with 91 CRI. Good.

If you use natural gas you might look to your gas company. I had National Grid do an energy audit on the house last year and during it the auditor changed all of our light bulbs to CF's for free. They even put in dimmable bulbs, and ones that looked like decorative bulbs if they were visible.

i do have natural gas for heat. however, i turned off the heat some weeks ago now, so am "solar" :) good insulation, two big solar inputs (glass door/window), but of course a TV == more than warm enough now that it's not freezing. heck, keep the windows open some nights now.

i just don't like CFLs in my personal spaces.
