How to calculate the k (colour temp) of a combination of bulbs?
Hi All,
I am coming up to needing to replace 3 (of 6) of my t5 bulbs and I have been reading a lot about color temperature and growth rates etc etc.
However, all the info refers to 10k, 14k or 20k lighting. If you have 6 bulbs all with different color temperature then how to you come up with an overall figure? Is it just an average?
Hope someone can ear this up for me.
Ta,
Dunc
