Applications:    CB series Beam280 is suitable for live performance, theater, touring show,theme park,church,club etc.       Beam280 is a very bright and super-fast with a sharp parallel beam that cuts through the air and across video with ease. It can project a static or rotating glass gobo to produce precision in-air and surface images with an even focal plane. Tight or at full 20 degree zoom, the output is crystal clear and brilliant. Add in either rotating, 6 way linear or 8 way circular, prisms to create wide reaching effects across any set., lightweight body – due to the efficient short arc 280 W discharge source and the Robe optical configuration. This new technology fixture even travels efficiently in a case of 4 and will cover all your needs – Beam, Spot, Wash, FX - there is no point in using any other fixture.

HRI 230W is 11200lux,Both color temperature are 7500K.The Life Span: HRI 280W HRI is 2000 hours and 230W is 2500 hours.(The following are original OSRAM bulb, not projection bulb)2．Optical280W beam lights was used three groups of optical lens (Image lens, zoom lens, magnifying Lens) offering a better spot and color adjustment. As different optical configurations, which get the different optical view. 280W beam light is 0 degrees -25 degrees.While 230W beam light only has a single set of optical lens. No zoom and magnifying function. The Beam light angle is only 0-3 degrees.3.BrightnessWe selected a Beam 280W beam and Beam230W beam lights randomly for testing, at distance of 8 meters. Spot diameter is 60CM We measured the data of each unit as below :  Beam 280WBeam230WMiddle960*100 Lux755*100 LucUpside115*100 Lux40*100 LuxDownside124*100 Lux36*100 LuxLeft120*100 Lux48*100 LuxRight136*100 Lux46*100 LuxColor7400K7900KTemperature  4.Gobo Wheel280W beam light have a fixed gobo wheel (14 static gobos), and a rotating gobo wheel (9 rotating gobos). Ensured both image and beam are perfectly performed. Moreover, The gobo wheel cut through the beam automatically, which produce precision in-air and surface images evenly. 230W beam light only with one fixed gobo wheel (17 static gobos)5．Prism Wheel280W beam light have a Unique 6 way linear prism wheel, and a 8 way circular prism wheel. Both can be adjustable by focus. This is the reason why Beam280 can show a very clear and clean image than 230.230W beam light only has one circular 8prism wheel. Sometimes, The gobo have virtual shadow when we turn on the prism.6: WeightThe beam 230w's net weight is 18.5KGThe beam 280w's net weight is 16KG
