Hi all,

Got a customer who is having a wood burning stove fitted and wants some kind of light inside the chimney to light it up.

I said it will need to be heat proof...am about to start looking but does anyone have any suggestions please?
 
Customers heh? You can’t live with them and they keep changing their minds!
 
Unless its a very big fireplace and / or chimney I would be telling that its a very bad idea ...........

We have a wood burner and the heat radiated off it is rather too high for anything electrical IMHO

Yes we've got one too and I feel the same really but then I thought you have a light inside your oven so maybe it's possible.

I'm guessing you've done a google search for heat resistant lights, cables etc .....

Yes haven't really seen anything convincing, thought someone may have had the same request. I've fitted lights in a mantle piece before that came with the lights as a kit, inset into the faux beam but I suppose while that area gets warm it doesn't get red hot. They were g9 or g4 capsule like you'd fit in an under unit light before the LED ones came in.

Thought there might be something like the glass light in an oven with the pygmy lamps in not that I've been able to find anything remotely suitable...yet
 
I had a quick look on the site this morning when you first posted. The only thread I could find was from quite a while ago... 3 posts, nothing of note in it.
 
I've been having a bit of a mooch around on-line, and there are lots of components that can handle the higher temperatures if you wanted to make something custom, say a series of low voltage MR16 lamps. Holders and cable, no problem. Jointing, ceramic terminal blocks. LV transformer out the way. Silicone cable, some of it good to say 180 deg C.

I think in this day and age though the limiting factor might be the lamps themselves. The LED ones are all plastic and are likely to be affected by the extreme heat.

Another option might be to have the lights down low, below the base of the burner and use them as up lighters?
 
Thanks for the response. I agree about the LEDs I think they're a no no, even changing a normal lamp is likely to get you a bit sooty. Yes under the stove is an interesting idea, I've got a stove at home I'm going to have a feel round the back when it's lit and see how hot it gets round the back and underneath. I think what the customer has in mind is something out of sight so they can illuminate the chimney and brickwork when the stove isn't lit and add a bit of ambient light but clearly the issue is the heat rising from the stove.
 
I'm sure there are ways round it, like carefully crafting chimneys and sinking the lights into the side of the chimney so the heat pulls cool air from low down up over the lights to keep them coolish, but it's like where do you draw the line?

I had a look for kits and there's plenty of fireplace lighting kits, but couldn't find anything really suitable.

Did find one thread, I think on the IET forums about someone who had done it with LV and catenary light fittings strung between two steel wires. They said the fittings and lamps (halogens not LEDs) handled it well, but the wires plastic coating failed (no surprise).

I saw that on there as well. It's all a bit macho on there for me, they all try and out clever each other :) and usually make some pretty daft suggestions whilst trying to look clever. Had a similar customer once who was arguing that I had to bond his sink and he was a member of the institute of electrical engineers so I went and got the regs book and he backed down and admitted he knew nothing about domestic. A bit off topic but he was alright really.
 
You can make a bespoke set-up,using oven equipment,but it would be a lot of effort,just to have a better view of a flue...

My choice,would be a clear,pyrex flue,and some magnesium,mixed in with the logs...
 
You could use a 12v MR16 halogen downlight lamp with the transformer mounted remotely somewhere cool and fibreglass insulated wiring in fiberglass sleeve between the lamp and the transformer. I've seen this set up in fireplace chimneys on several occasions but I'm not sure how much longer the halogen lamps will be available.
 
Ive fitted gu10 spotlights in corners of large fireplaces with no problems, brought wiring in from side into back of fitting, where ive had to run accross fireplace used fp with p clips, no problems.
Mountain of a mole hill springs to mind from some posts.

I have given you a disagree .... on the basis that you have made it out as if every body with a wood bummer can do this .... we can’t.... our fireplace simply isn’t big enough
