The Eiko 4416R stoplight lamp is the perfect fit for any installation that uses a PAR36 bulb. The red colored light reflects a 6000 candlepower beam with an 11 x 4 spread. This 30-watt bulb uses a universal slip-on and screw base to simplify mounting. The standardized size makes it easy to replace your current PAR36 bulbs without worry on whether the light will fit. This signal light has an average lifespan of 300 hours and is useful as a red spot lamp or in signal lighting.
