A few years a go I was on set shooting BTS of a fashion commercial and the Photograher was using them. They're an unusual looking light source but they produce the most incredible light source especially if you place a model in front of them.
They come in a variety of sizes and in both Tungsten and HMI

What makes these lights so special is the silver textured dome that can be used as a background. But equally you can focus the light by retracting the centre column to create a more flooded or spot effect.
We're shooting a Brazilian Samba dancer so I'm looking forward to seeing how the images will look.
Here's a promo film made using Briese lights
Have you used them? I'd love to hear your experiences if you have.
