My dad sent me a link to an interesting product from Rosco called a LitePad. According to the site:
Rosco LitePad™ is a slim profile light source that generates a soft even beam of light and almost no heat. Its small form factor and light weight make the Rosco LitePad™ perfect for use in many places where a larger, typical luminaire could not fit. Drawing just a few watts of power, LitePad is simple, fast and economical to use in film and television, theatre and live entertainment, and retail and event lighting.
Ranging in sizes from 3×3 to 12×12 – either square or rectangular – the LitePad is about 1/3″ thick and has a lamp life of 100,000 hours, producing a color temperature of 7,000 degrees K.
Though it is advertized for use in film, video, and stage as accent lighting or to illuminate objects/subjects in hard to light places, I could certainly see how this could be a useful addition to any lighting kit. I’ve looked around and haven’t found a price yet but
