The 400w Joker Bug combines the characteristics of the BUG-LITE 400, a 400w daylight HMI system without optics, to those of the Joker 400, a PARD 46 fixture using a specular parabolic reflector and a set of 4 lenses. The JOKER-BUG 400 is comparable to a 1500/2000w quartz fixture, but with a power draw of 5.5amps.

In the Bug-Lite mode (no optics) the main application is in traditional Lightbanks as well as Lanterns where it uses the sides as a large reflector, collecting the maximum output of the lamp and filling the front screen very evenly. It is very powerful in daylight interiors and can operate in any position including pointing straight down.
The BEAMER optical accessory turns the BUG-LITE into a JOKER-BUG, a directional PAR unit offering various beam patterns through quick lens changes. The JOKER-BUG 400 offers the most flexible optical configuration for location lighting by achieving Spot to Flood ratios of 80 to 1 with beam angles from as narrow as 5 degrees to as wide as 55 degrees.The JOKER-BUG 400 is delivered with a Clear Glass Beaker when reaching for full intensity is important, and a Frosted Glass Beaker when light quality is the prime concern. The 400W MSR lamp was selected for its size/weight and the sizes/weights of the components needed to operate it. The MSR lamp with its GZZ 9.5 base is considerably smaller than the next traditional Wattage, the 575 (G22 base); this in turn allows for more compact and shorter fixture design. The shorter arc gap of the 400 makes up for the difference of output between 400 and 575 and the lower Wattage does not require forced air cooling of the power supply.The small, quiet ballast can be hidden anywhere and plugs in any circuit without risk of overloading. With the Slimverter 400 and two 30 volt batteries, the JOKER-BUG 400 is the largest 30 volt battery powered HMI. Motion Picture Gaffers and Freelance Cameramen have adopted the JOKER-BUG 400 for fine daylight interiors, car shots, two camera interviews, TV magazines, documentaries and industrials.
