Greetings,

My first post, hope it is fruitful. I recently got my hands on some Fresnel and I am in the process of refurbishing them one by one. I went to my electriacal supply to buy some wiring for them, and relized, I have no clue how hot these things get. I am planning to put no more than a 750 bulb in these. So hot is it going to get? I need to know this or my insurance rates will go through the ROOF! When I pulled these apart I found the cable to be 90c, I don't want to trust whoever wired this before me B/C the wiring was really shotty.

In the olden days, the high temp wire had woven asbestos insulation. Today they probably use teflon. You might look at the same makes and models at a rental house and see what they're using. Or check the manufacturer's web site, they usually sell parts.

I can get the wiring, no problem. I just need to know how hot the lights will get with a 750w bulb in it. I can then figure out which wiring will suffice.

Depends on the light, the design and the bulb. Check the parts catalog for the manufacturer of the product you have for the type of wiring they use currently.

TFE wire ( teflon with glass braid cover ) @ 250C is good. 3M Scotch #27 Glass cloth tape to cover switch connections and wire splices. I am used to rewiring all my fixtures every 7 - 8 years due to humid Florida weather....
