Unless it's on all day and night I don't imagine it would be possible to melt wire, though don't quote me on that. lol
I use a 150W Fluker's Ceramic Heat Emitter (100 will probably do, originally bought these for my hedgehogs), suspended about 5" off the lid because I have a top opening tank (ugh), which is attached to an Inkbird ITC-306T (Not the best, but really cheap) thermostat to control temps. The fixture alone only gets to about 140F.
While I'm not 100% up on my tube UVB, I've seen 60cm fixtures recommended for everything from a 40g breeder to a 120g.
