PLT's 1.5 watt blue LED lamp features a single contact bayonet base and is designed specifically for landscape lighting retrofits. It is energy efficient, water resistant, and features a multi-directional beam pattern, making it ideal for pathway lighting fixtures. When used as landscape lighting, its deep blue color pairs well with green LEDs to make grass and green foliage appear more lifelike than green LEDs alone. At 20 lumens, the bulb replaces 15 watt halogen bulbs. The lamp features a replaceable diode, allowing you to change the color of the light produced.
