CCFL (Cold Cathode Fluorescent Light):

I thought Id give some information about the CCFL light I use on my camping powerpack.

Each tube is about 30cm long and uses about 5 Watts at 12v. Thats about 0.5A. Each seems to give about 15-20 watts of light which is very good for the power it uses.

They take a minute or so to get to full brightness, because, although classed as "cold", they do infact need to warm up inside and they feel slightly warm to the touch when they have been on for some time.

They are easily bright enough to light up my bedroom which isnt all that big but its enough to cope with normal tasks.
