If I recall correctly, the flames of a wood fire are around 600°C. I really don't think there is any realistic mileage in what you are proposing.It will go over an open wood fire, so there will be flame about 1M below. I imagine it looking exactly like Fluorescence's picture. ... Could I connect the Bosch oven lamp and housing (I put picture in earlier comments) in this way? I would really appreciate a link to site that sells a suitable heat-resitant cable like the one mentioned for 180C.
What actually is this chimney?
I have the same problem but, in the manner that Lower has suggested, I have a couple (to avoid shadows) of spotlights illuminating the area of the BBQ 'from afar'.I need to light on when the BBQ is on - so that I can what I am cooking.
I think that bulkhead fittings like that often have Pyrex-type glass, so probably are pretty resistant to heat, but it's the wiring that is the main problem - which enters the fitting from behind and is presumably usually buried in whatever the fitting is attached to. Particularly if any of the cabl;e were even remotely 'exposes, I think you would be very hard-pressed to find any cable that could safely cope with the potential temperatures (and even potential flames) in your proposed application.
I know it is possible, because this type of BBQ is popular in Argentina and they usually have lights inside. But I can't tell what type of lights as they are spanish websites...
