if youre willing to put some time and energy (and maybe a couple bucks) you could build yourself a cooltube for your light, just something clear to encase it with fans on either side to cool it, i've seen plans around here somewhere on the site, i'm kinda baked right now but i'll dig around here in a bit if no one else comes up with them

theyre not hard to design at all, plexiglass has a pretty high melting temp so you could use it to encase the light and mount fans either side. cheap and effective.
