Eyecave
I think i remember reading somewhere that grease, from hands etc., effects bulbs formed from a certain glass, you are right they do eat batteries.
Huw
I am sorry but I must continue to moan about Speleotechnics.
Big trip on Saturday and I forgot my light :!:
Not a prpblem nip around the corner to nice people at Hitch & Hike and hire one, an FX3.
One hour into an eight hour trip and the main bulb failed :evil: . I had to do the next seven hours on the pilot bulb :x
The trip was one where you end up covered in mud all of the time and we did not have time to start fiddling with crappy lights so I just put up with it.
When I got it cleaned up and returned it we discovered that the switch was faulty :x
I have seen this same fault on my mates FX Ion, it appears to be a problem with the FX headset, not good, not happy.
