Brilliant solution!
I've been surprised how hard it's been to find a decent fluorescent tube replacement in warm white. Most seem to be daylight (ok) or cool white (ick), are too bright, or are out off stock in the sizes I need (combo of 600 & 1200mm). But then I found these little beauties, simple switch for color temp and good light level without being too bright. Very happy. I'll be back.
