Yeah, with 3 x 1W LEDs as a point source you would probably need to worry more about blinding your subjects, than just overexposing them. The lenses that fit over the LEDs are wide angle so they diffuse and spread the light, although they may still be uncomfortable to look at.

You can use a pot (it would need to be rated at probably 5W) but you can probably buy off the shelf Luxeon drivers which include dimming.
