Well I've just had a bit of a shock. I bought some LED light bulbs and normally I get cool white bulbs but this time I bought some warm white as they were on sale and there wasn't a choice. However on getting them I was shocked at how green the output was! It was immediately visible and was much worse than on other lights I have encountered even with flo's. Of the bulbs I bought the little candle style bulbs seemed the worst. The bulb shaped bulbs were still bad however. I put one of the candle style bulbs into a lamp with a shade all around and it lit up quite green and with the addition of some orange gel it became quite bright yellow like you might find in a highlighter pen!
Is it the case that warm white is a lot, lot less colour accurate than cool white?
The cool white bulbs look a bit blue but I've generally had good experiences with them.
I think I will avoid warm white in the future unless it's for a special effect!
