Looking for help with a radio or IR circut

[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!!
