Thermally efficient compact fluorescent fixtures [PDF]
Conference Record of the 1990 IEEE Industry Applications Society Annual Meeting, 2002 A series of prototype fixtures that employ convective venting and heat sinking to reduce elevated lamp temperatures is described. Experimental data show that decreases in fixture efficiency can approach 20% due to elevated temperature conditions inside the lamp compartment.
