Thankfully and sometimes regrettably, I rarely throw things away. I have a couple of old aquarium lights from which I've cannibalized sections of reflector.
Ben, more of your heat will now be going ^up^. As I'm paranoid of fire, think twice about walking away and leaving the light (heater) on.
I'll stay with it and will not leave it.
Like a lot of you guys , I have a lot of things within 5 feet of my Lubesizer that don't need any contact with fire ! !
