The effects of fixture type and HVAC integration on fluorescent lamp/ballast performance

The effects of fixture type and lamp compartment air extract on lamp/ballast performance are described. A luminate/plenum/HVAC simulator was used to measure minimum lamp-wall temperature inside four fixture types while varying lamp-compartment extract conditions. Experimental data show that the lumen output of the lamp/ballast system varies by 20% and system efficacy by 10% depending on the type of fixture and lamp-compartment extract technique used.<
