Rifa Light - Tungston
		Creating beautiful soft key or fill light doesn't have to be strenuous or time consuming. Compact, lightweight, & self-contained, the Rifa-lite uses a simple design approach as old as the umbrella to achieve its quick & easy setup and strike capabilities.   Bathe almost anything, from talking heads to table-top stills, in luxurious almost fool-proof soft light. It is the perfect complement to today's compact, light-sensitive, digital cameras & filmstocks.

Easy access to pockets on fabric shell allow clip-on gel attachment for correcting to daylight. Light controlled with fold-up accessory fabric Egg Crates.
Omni Light - Tungston
		The wide focusing range of the Omni-light makes it a flexible key or back-light. Add diffusion or an umbrella, and it's a soft fill source. Swap the power cord & lamp and it becomes a battery powered, hand-held light. Available with a host of accessories and built for heavy duty long life, the popular Omni is the perfect companion to the Tota.  Multi-use, tungsten halogen source. Double parabolic, peened reflector provides non-crossover beam for maximum efficiency and gel life.
Totas - Tungston
		Compact, rugged & versatile, the broad throw Tota-light  can be used with its umbrella or gel-frame & diffusion as a soft key, fill, or backlight. With its adjustable reflectors, it can be a smooth & even background light, or point it toward the ceiling to raise the ambient (base) light level of a room. Tota is also widely used for photographic copy work.  Multi-use, tungsten halogen source.

Fresnel Light
		In the studio or on location, for those who love the beautiful light quality of a fresnel, there is simply no better choice than the Lowel Fren-L 650.    Designed with input from working professionals, the Fren-L 650 features an oversized swing down handle, a pop-up scrim holder for easier access, double walled convection cooling, and a single arm stand-fitting yoke for a generous tilting range without the cable snarl. With an impressive 8:1 focusing range, it glides from an exceptionally wide even flood to a tight spot with sharp shadow quality.
