I plan to replace a CFL lighting fixture in a small room (10' x 15'), due to its being too dim and giving less-than-perfect light.
I'd like to install something that would give me 3500K light with color rendering index (CRI) ≥ 85.
My options are seemingly halogen and LED. I'm OK with replacing the fixture, adding transformers, etc.
- Halogen bulbs I encounter seem to have low power efficiency, below 20 lm/W (example). This means lots of heat, which I would rather avoid.
- LED bulbs I encounter usually have CRI of 80 or worse (example), which I would rather improve on.
What am I missing?
