DOH! You are correct and I should have checked my sources before posting. The model 15 was equipped with a 100cp bulb and the optics produced a 40,000cp flash. Whelen's Rota-Beam series beacons used 50cp bulbs and the optics produced 8,000 to 10,000cp flashes. In comparison, the standard 12 volt 4416 sealed beam of 35 watts was rated at 35,000cp.Sirenman said:The standard bulb used in the 15a was a 100 watt spherical bulb #1019.
Both the 15, and the Rota Beam will accept a 795X halogen, increasing the light output nicely, with no negative results. Good idea for anyone thinking of a retro light on their vehicle.stansdds said:DOH! You are correct and I should have checked my sources before posting.
