Page 2GENERAL INFORMATIONMajor ComponentsYour overhead luminaire is specifically designed to meet the needs of visual color evaluation. The housing finish is non-UVabsorbing and non-yellowing. The reflector is constructed to provide even light distribution. The diffuser is made to controlbrightness and resist environmental effects. The daylight fluorescent lamps use X-Rite's patented seven phosphortechnology providing the closest approximation to natural daylight in a fluorescent source.SET-UPInput Power RequirementsX-Rite overhead luminaires are designed for 100VAC/ 50Hz, 117VAC/ 60Hz, 220VAC/ 50Hz-240VAC/ 50Hz, or277VAC/ 60Hz operation. In all cases, proper input power is marked on the box and fixture label.CAUTIONDo not operate fixture on DC input power.Fixture Power ConsumptionExamolite TC-440B 368 wattsExamolite SD-840B 552 wattsProoflite PLD (4-lamp fixture) 184 wattsProoflite PLD (8-lamp fixture) 368 wattsNote: Prooflite Models PLD50/65-840, PLD50/75-840, and PLD65/75-840 operate as 4-lamp fixtures.Circular Knockouts (not shown)Ballasts (2 or 4)Center Brace Circular KnockoutsGroundsReflectorDiffuserFluorescent Lamps4 lamps 440 models8 lamps 840 modelsExamolite TC-440B Users Only:Place metal cupover end ofincandescentlamp Press tab inwardFigure 1.
