Hi all

Well after 2.5 years of solid reliable usage, something has finally gone wrong on my little Halcyon Proteus 3 (fixed focus) torch. Of course it didn't help that this happened before dive 1 of tech 2, but these things can't be helped.

So can anybody suggest what could be wrong:

The light attempts to fire, with a flickering from the bulb for about 5 seconds before giving up. I have tried 2 different fully charged batteries. I took head apart earlier, and all the wiring into the ballast looks intact, and the bulb looks to be fine. The wiring at the lid end looks perfect.

When the light attempts to fire, there's a quiet buzzing like sound. Attempting to fire the light without the bulb still generates this sound, so it must be coming from the ballast - it never did this before.

I don't have a spare bulb to try.

I might break the wire connections into the ballast and connect it directly to the battery, but I've got a feeling something is wrong with the ballast.

Any help appreciated before I send it off for repair.

Cheers
andy
