11th November, 2009Portable Blacklighthandy though limited"great and effective in checking the fluorescence of objects in shops though you would need to shield the item from daylight. in semi-darkness you hold it 10 inches away from things and you can see them glow so is perfect for demonstrating fluro details on things. it is not a substitute for a ceiling-mounted blacklight of course. but i guess you could put 5 of them together in a small tent at a festival and have a portable night time UV room ;) the bulb cover (clear plastic window) also shines slightly greenish/whitish. works fine off recharcheable batteries (1.2 volts each) I have yet to try it on full normal batteries (1.5 volts each)"
