This Precision Lighting 1.5-watt blue dimmable LED diode is designed to replace diodes on Precision Lighting 1.5-watt G4 and 1.5-watt single contact bayonet base LED lamps and has a long life of 35,000 hours. Its deep blue color pairs well with green LEDs to make grass and green foliage appear even more lush and lifelike than with green LEDs alone. It is energy-efficient, water resistant, and features a multi-directional beam pattern, making it ideal for pathway lighting fixtures. This diode has an initial output of 20 lumens and is a 15-watt halogen equal. Whether you want to change the color of your LED light for seasonal applications or replace an existing diode that has burned out, this is the product for you.
