American Cinematographer - February 2008 - (Page 75) Light “skirtless” HPL Space Light. Utilizing compact filament HPL bulbs developed by Ushio specifically for ETC Source Four fixtures, B&M HPL fixtures pack the same efficient punch as the Source Four from the same 750-, 575- or 375-watt bulbs. Made possible through a license with ETC, B&M’s use of HPL globes with lightweight, removable, parabolic reflectors also integrates the Source Four concept of interchangeable lenses for stipple, wide, medium, narrow and very narrow spot (VNS) focus. The lenses and reflectors are held in place with a simple tension ring and require no tools to change; it took me about two minutes to change out all six lenses on the Mac Tech fixture the first time. And because they use HPL compact filament bulbs, B&M fixtures use less electricity and generate less heat than the larger 1K Par 64 fixtures normally found in six- and nine-light fixtures. The fixtures are well constructed and extremely robust. Both have Socapex connectors for easy connection to a dimmer system, and they also offer Socapex to Bates adapters for those working with constant power (or with non-Socapex distribution). Unfortunately, I did not have the opportunity to test the fixtures with a dimmer system. With the Bates connection on the Space Light, it’s either all on or all off; there is no individual control over the six globes, nor any power switch on the fixture. The Mac Tech, however, features six individual switches that enable the user to turn on as many bulbs as http://www.backstageweb.com http://www.bmlighting.com http://www.bmlighting.com
