This paper describes the effects of fixture type and lamp compartment air extract characteristics on lamp/ballast performance.

A luminaire/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 employed.
