Can anyone recommend an eye light fixture. Want very low wattage which will not interfere with primary lighting - for studio and mobile shoots. Would like camera mount option and battery powered. Don't want anything more than to put a sparkle in the eyes.

Litepanels MiniPlus LED lights are nice, they can be diffused and have a dimmer on the unit, though you have to use your fingers, but this can be handy as the camera comes closer, you can dim the unit down. Both daylight and Tungsten units are available.

Kino Flo Mini Flo fluorescents are also nice. They are 12V and come in 9" and 12". There are other sizes as well, but for eyelights, those are usually the size people use. The ballast has a dimmer in it and the ballast is remote from the head making dimming easier, if the unit is mounted on a camera. Kino bulbs are available in daylight and 2900 K.
