Grave Mistake

I'm a magican/illusionist and alot of my props and illusions deal with effecting things outside my physical touch. I've been scouring the internet for some type of either radio controled or IR circut. The basic premis is this. A lighbulb is help in a spectators hand and the light suddenly begins to softly glow and then gets brighter without the illusions touching it at all. What I'm thinking of is using a trick battery opperated light bulb and some type of hidden dimmer receiver in the bulb that is controled by a hidden controler that is on my person someplace. Most of these trick lightbulbs just use a single AA battery and a cheap metal ring that makes them light. This would take this illusion to the next level. Can you help me in some way to find more information on this type of circut?? Maybe just point me to someplace that might have something similar or something like that? Any help would be greatly appreciated!! Kohl ~Grave Mistake - Magican / Illusionist~
