Hidden fire place lighting around log burner - whats ok?

[readiescards]

We have a fire place with (when its fitted) a 5kW room sealed log burner sat inside the chimeny breast.  As per our previous house we wish to have some hidden lighting up in the chimney breast that illuminates the fire place and log burner (probably 2-3W LED).

 

The electrican has installed the wiring and switches etc but wants the log burner installed (Hetas registered) to state what lights are acceptable.  The Hetas guy has had many weeks to come back to me on this but seems to be struggling to get a definite list of suitable items.

 

What is allowed/not allowed in such a situation.  Would a simple cermanic baynet holder and a cooker rated LED bulb be ok?

Interesting one. I don't have any specific knowledge on this but surely the critical thing is the distances involved- your stove should specify a minimum distance to combustibles.

You could also shield the cables e.g. in metal conduit.

I doubt the stove maker will be able to help.

 

I think your best bet is to get the stove installed, fire it up and measure the air and surface temperatures where the lights will be installed. Then find lights that are rated for that environment.

 

I doubt you will find lights that are specifically rated for use close to a wood burner, not because it's difficult to make lights to go there but because they don't test lights for suitability in in every imaginable location.

I found a ceramic holder that claims they are suitable for upto 210C. But it's not quite the right type...

It looks like standard pvc twin and earth wire is only rated to 70C. The flex used on irons appears to be ok to about 150-180C I think.

Something here maybe:

Reflective mirrors.....Pyro.....FP cable.....angled / shielded spots pointing up mounted low on the hearth.....???

What about using light pipes to give you the distance between the light source and the stove? If that is impractical,then the oven lights mentioned above would probably be a good bet.

Low voltage LED ..??

 

if you have a timber mantle then it will have to be outside the combustible zone anyway so the LED strips should work even if they get a bit warm.

Seems the best plan, especially as it might be the 'fire it up, fook its hot, never use it again' scenario

Seeing temperatures of sub 50 degrees within the recess so no where near as high as I thought.

 

Plan to install some simple ceramic bulb holders:

Connected using immersion cabling which I believe is rated for 85 degrees
