Re: Lighting for smoke
MNH makes a good point, I have heard of LED's under the vase but never for the smoke. It sounds cool though. Personally, I feel the best smoke effect is a dim yellow light even candlelight if possible. The yellow light allows you to see the smoke better than in white/daylight but doesnt give you a headache, like sitting under a red or other colored light does after a while.
Maybe im just that way, because thats how we smoke at home. But definately let us know what you decide and how it turns out.
