Any idea the make of the ones you have? Mine are by Tru Opto but no mention of whether they are waterproof or not. Was thinking at the time that they would be good under the cover and was going to test them out to see but just that day a guy came in with a nice twin tube head off a street sign so I cut a hole in the sliding covers lid and fitted that instead.

They are generic from the local electronics supply place so no branding sorry, i can tell you they are a meter long, run on 12v and cost about $40 US a strip - ouch!
If its fluorescents that you are talking about I would probably avoid them, the blasts converts the standard supply to a few thousand volts and they contain Mercury (the manufacture recommends burning your cloths if one smashes and your near it).
But then I read an article the other day that said that you guys (US) are putting Mercury in some of your vaccinations now, so the fluro mill lighting is probably the least of your worries.
