The IGL18B is a sealed outdoor lighting well light that uses an MR16 lamp. The socket is mounted on an adjustable gimbal so the lamp angle can be adjusted. The top is thick solid cast brass. The commercial outdoor lighting application glass lens is flush with the top so water cannot puddle. There is a thick rubber gasket between the top and body of the well light for a watertight seal. The lower canister is completely sealed - the round lead wire uses a waterproof pressure fitting to ensure water cannot enter from the bottom of the well light fixture. We offer a variety of solid cast brass top options for in ground lighting application. Install it with our Heavy duty PVC Well Light sleeve which provides durable housing for all Brass In-Ground fixtures.
