Lights for hot location

[adamr7747]

Hi All,

I'd like to install some lights (perhaps a couple of wall-mounted spotlights) in a large inglenook fireplace. The air where they'll be gets pretty warm and I've read about LEDs not coping with heat so would like to use halogens. However, it's pretty hard to get hold of halogen GU10s, so I'm looking at MR16 lamps, with a transformer away from the heat. The trouble is I can't find anywhere which sells surface-mount MR16 fittings. Anyone know any? Or any alternative suggestions?

Thanks a lot,
Adam

I may possibly have a box of bulbs here still, not quite sure what they are/were.

What's that in Centigrade?

If there out of sight, in pubs we use Glass fronted Bulkhead fittings that take standard Bc lamps, Yuo can still get Tungsten lamps and likely Halogen lamps if you look about.
Though the supply cable also needs rating for the Temperatures its fitted in

If you conceal them you could fit oven bulbs and porcelain fittings + heat proof wiring?

An appliance bulb for ovens etc, will take a fair amount of heat, however porcelain lamp holders are not that good looking, so I would thing twice over fitting heat resistance lights.

Thanks for all the comments

Fair question! I'm not sure. I can stand in there without expiring, so I'd judge it as technically "very hot airing cupboard" temperature . Next time I have the fire on I'll find a thermometer...

Thanks, good idea & they will be concealed & I already have heat-resistant cable run in there - but I'd still like directional light ideally.

Thanks for the idea (& ericmark), though I can't imagine oven lights would be bright enough. I'm also not sure I've ever seen, or know where to find, surface-mount fittings for them?

i think a light bulb will do the same.

remember, they are often inside enclosures.

Maybe you could use something like this, you can likely bin the lampholder and fit your own GU5,3 to take your 12 volt Mr16, sometimes easy if the lampholder is floating and the screw on cover secures the lamp, however if the Gu10 lampholder is screwed on, then you may need an adapter to fit

Try a search for GU5.3 fittings and you may find something suitable ready made for 12 volt lamps

I finally got round to measuring the temperature where the lights will be and it only got up to 31 degrees - so I suspect I'm over-thinking the problem! I'll stick in some GU10 fittings and see what happens.
