Constant wattage ballast
Constant wattage ballast although heavier, larger and more costly provides numerous advantages over reactor-ignitor gear. The lamp output power is maintained at a highly constant state, even over supply fluctuations, due to the regulation action of the auto-transformer. Hence the name Constant Wattage (CWA).
