Another DIY Light Question

My DIY headlight project is stalled due to a friend's observation that my
original lens material of choice (Lexan type stuff) will probably melt from
the heat of the lamp (G.E. "Quartzline" FHX 25 watt). Is this true? All of
my original assumptioms about the amount of heat these things produce are
apparently wrong (my buddy pointed out that my original choice for wiring is
also not robust enough). Suggestions?

Thanks!
