Power must be OFF when installing lamp.
Note: If a lamp is being replaced, and it had an external ballast wired between the power source and the socket, the ballast needs to be bypassed (Operating Voltage 120 VAC). LEDtronics recommends removing the old ballast to avoid any possible use with LED lamps.
When Installing Lamps In Potentially Corrosive Outdoor Environments
LEDtronics suggests that a silicone moisture-barrier sealant be used to protect the metal-threaded base of the LED bulb.
Sealant is highly recommended for all outdoor-environment LED bulb installations to prevent water and/or moisture incursion that can lead to premature degradation of the bulb base and eventual bulb failure. This is especially recommended
for LED bulb installations near saltwater bodies
Dow Corning Molykote® 111 Compound (Valve Lubricant and Sealant) is a high-temperature, moisture-resistant, silicone grease. If liberally applied to the clean surface of the lamp socket and the base of the lamp itself, it will provide moisture and corrosion resistance.
