Tunable ballast

A commissioning tool allows users to “tune” the DemandFlex B228PUNVDRH-D ballast from Universal Lighting Technologies to avoid over-lighting. The ballasts can operate two F14, F21, F28, or F35 T5 lamps with an input range of 120 to 277 V. The power level of an individual ballast or whole circuit of ballasts can be turned from 100% down to 35% with 1% increments (or a ballast factor ...
