Is it a case of changing the entire lamp assy?

I thought you meant the ones with the triangular key as well.

If you Google search for the particular torch you have and include the word "manual" or "instructions", you may end up with something like this:

edited to add:

If you don't know the manufacturer, use "intrinsically safe torch" as your search term, but expect to trawl through loads.

Thought that, but then why supply spare bulbs in the base?

The nearest that I can find to instructions is

The Torch has a stainless steel EX Â´eÂ´ self locking bulb capsule. This allows the torch to be opened safely in hazardous area to change the capsule if the bulb has blown.

Tried that. Think this is Safety Torch EX250.

Guess I'll have to. Was expecting a G10 guru to pop up and answer it!

Cheers for info.

Are these not intrinsically safe torches for use in explosive atmospheres?

If so, do they not have to be returned to the authorised repair agency for testing after being opened?

...Usually the reason that it is difficult to get in to a bit of kit, is because you are not supposed to!

Damaged intrinsically safe equipment has to be repaired by somebody competent, usually an authorised repairer, but replacing batteries and the bulb in a torch is a user responsibility - that's why they're supplied with a key. The lock should be fashioned in such a way that releasing it cuts the power before the casing can be opened. I've seen loads of "dud" batteries thrown away because the user hasn't locked the case shut before checking that the bulb lights.

The big problem is that when you draw them from G10, no instructions are given with them (presumably thrown away with the packaging - after all, it's only a torch), so you have to work everything out for yourself - and each manufacturer has different ideas about how to lock the case.

Just to add, some torches have a sealed beam unit that is, indeed, a workshop job because the unit forms part of the outer shell.

These are a bastard to open, you should of been supplied a tool along with the torch to do this.

If you need to open it then do this:

You see the little slit in the side, the little cut away at the top of the unit, this are the part which allows you to unlock it.

You have to push the piece of metal behind the slit in all the way and then twist to open.

Make sure to re-seal properly when your done, or else there is a much larger chance of moisture entering the houseing.
