I want to report just how dangerous this rig is. It got crazy hot. Fast. I found myself just hoping on hope that it didn't burst into flames.
It ended up melting the polystyrene, which I will use to help create the crater effect. But still!
Awesome shots! You're making it hard for me to not bite the bullet on the Acid Rain stuff
You might want to consider switching over to LEDs as they will be safer. They don't need to "warm up" like florestants, & are not as hot in incandescent lights.
If you ever consider doing a permanent display where you would turn & off the explosion at will, LEDs would be the way to go.
