2BL255  |  4BL455

Our most powerful fluorescent soft fill light source, the 4BL455 is a new and improved version of the 2BL455 fixture. Improvements include single lamp per reflector design for a more efficient,more powerful (80 fc at 10'), and more evenly distributed light output. The 4BL455 offers bank-switchability (on FUL and DIM models only) so that you can operate the outer two lamps only, the inner two lamps only, or all four for maximum effect. Aluminum construction yields a lower fixture weight of only 11 pounds. And the moveable nut plates enable vertical or horizontal mounting flexibility. The beam angle on the vertical axis is 53°, 100° on the horizontal.

PrimeTime reflectors are warrantied the lifetime of our broadcast studio lights. We use extreme testing measures, engineering expertise, and top-quality materials in the design and construction of our luminaires. Besides the quality of our reflector material, what makes PrimeTime reflectors unique? Our exclusive parabolic reflectors are bent at calculated degrees which increase our light output by 15-20%.

I worked with you to relight our TV Studio at the College of Media & Communication. The upgrade in lighting was not only successful but has already made a difference in temperature and light intensity in the room.
