## Questions & Answers

**Q: What's the size of the tritium tube?**
A: Hi. Mine are about 2cm long. Green gives off most light, blue tube is no way as strong. So for effect I'd go fro green. If a bought again I'd go for single tube and not the twin one.

**Q: Would this light up a  bed side clock at night**
A: Just tried mine in the under stairs cupboard - pitch dark and to be honest I could not see a thing with it. You can see a little reflection when you hold it about an inch away from anything but not hardly enough to make out what it was and I knew what I was looking at. Perhaps when your eyes get used to the dark a bit more you might be able to see a clock. It is more of a glowworm than a light.

**Q: What is the reference activity?**
A: If by that you mean the level of steady radioactivity from it, it's about the same as from a watch with a tritium dial like the Traser series. It's not hazardous.
