I've bought tritium (I'm in USA) about 7 or 8 times so far and the one I like best is http://www.ebay.com/itm/Tritium-Lamp-Vial-Tube-Capsule-Trigalight-22-5mm-x-3-mm-Glow-in-the-Dark-/141307746305?pt=UK_Collectables_Scientific_MJ&var=&hash=item20e6991801 Pay attention to the colors, some aren't as bright as others. Green is brightest and I've tries ice blue which is really good and yellow's not bad. I got a purple one somewhere and the colors nice but not as bright.

HammerHandI own the green and ice blue. Take note that these are not very bright at all and direct sunlight overpowers it. Green is decently bright and ice blue is a bit dimmer.

HammerHandDoes this get through customs alright? I feel like they probably would pick up any radiation but apparently not...

jmpetroThe vials emit no radiation, otherwise it wouldn't be legal to own. The particles stay inside. The glow comes from phosphorescence of the coating inside the tube that gets excited by the radiation.
