The STO40L floodlight lamp holder assembly from Stonco is a heavy‑duty aluminum lampholder for outdoor flood fixtures, supporting 150W–250W PAR38/R40 lamps. It accepts PAR38/R40 lamps with a medium base and features a deep integral cast 360° bell that shields the lamp and minimizes light spill. Designed for landscape and heavy‑duty flood installations, this lampholder pairs with standard outdoor flood housings to deliver reliable illumination where high wattage is required.
