I assume you have to LED lamps - warm and cold white.
This is the simplest formula that probably won't give very accurate results:
More complicated approach is to use a luxometer and create a table with multiple brightness points which can be used a reference to calculate warm and cold white levels for a given temperature.
This is the simplest formula that probably won't give very accurate results:
Code:
br = 100 -- brightness (0..100%)
ct = 50 -- color temperature (0..100%; 0 = warmest, 100 = coldest)
ww = (100 - ct) * br / 100 -- warm white value (0..100%)
cw = ct * br / 100 -- cold white value (0..100%)
log(ww, cw)More complicated approach is to use a luxometer and create a table with multiple brightness points which can be used a reference to calculate warm and cold white levels for a given temperature.
