It may be asking too much.... and probably is. The project is essentially a lightsaber. I've seen flashlights that put out high wattage LED current successfully so I have to think it's possible. I was using a STCS2 from ST Microelectronics, and except for the heat it worked great. http://www.st.…

High power LED drivers.. 2A, 10W plus, PWM control & low(er) heat?
