I just had a sales rep show me something called
LitePad from Rosco.
I can see a lot of potential uses for it, especially in tight product shots.
It's a thin piece of translucent acrylic that has built-in LEds.
Sizes range from 3" x 3" to 12" x 12".
Here's the specs from the site:
Color Temperature: 6000° Kelvin
Thickness: .3" (8 mm)
Operating Temperature: -30C - +85C
Lamp Life: 100,000 hrs.
CRI: 93
Power is 12V. DC which means it'll easily run off a battery belt or a car battery.
Light output at 12" ranges from 13 foot candles for the 3" x 3" to 113 fc for the 12" x 12" model.
Canadian list price ranges form $49 for the 3" x 3" to $415 for the 12" x 12".
BTW, the full kit (2 of each of the 6 sizes plus a bunch of accessories) is a mere $3600 Cdn :-(
