Cooling light

Work is still busy and afterwards I'm still thermal imaging. I only hope it is actually useful to someone.

Today's back blip is a shot of a compact florescent lamp (CFL) cooling down. Interestingly on this year's surveys I've seen quite a few people who have installed LED lighting, it's still expensive but it's no longer silly money and they are slightly more efficient that CFLs and more convenient being dimable and reaching full brightness almost instantly.
