Review: a must for any night time workers - gives a good light at night without the need for batteries or exposure to light
Review: Great little glow keyring - Much better quality than the Nite glowing keyring I had that snapped. For those that don't know these do not glow all that bright, so are not an alternative to a torch but glow bring enough to make them easily visible in a dark space. Nice and compact, glows as well as needed and not a bad price.

## 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.

### ⭐⭐⭐⭐⭐ Bright enough to read a book at night.
*by A***R on 4 July 2020*

This is a really good beta light, perfect for a survival tin. Not as bright as a tourch, but certainly able to read a book in total darkness. Very impressed.
