12V halogen lamps are over-run when powered by 14.8V Li-Ion batteries. This can shorten their life and reduce battery run-time. The PowerMax unit regulates the running voltage to 12V, thereby prolonging battery run-time and extending lamp filament life. VariLux is a lamp dimming facility which controls light intensity without affecting its colour temperature. The VariLux dimmer control knob is situated on the rear of the PowerMax unit. This feature also conserves battery power. Paglight is the ultimate TV News camera top-light. No other camera top-light matches the performance or versatility of the Paglight system. Its unique patented design allows LED, tungsten halogen and HMI arc lighting technologies to be used with the same lamp head.
