TPI/Fostoria have been manufacturing quality dock lights for many years.  The last couple of years TPI/Fostoria have been busy in the research and developing department to improve and update the quality of the dock light.  Many changes have occurred and we now feel that the NEW and improved product is the best on the market with a very reasonable price for the customer.
New changes have occurred with adding electrical outlets to the arm, an 18" long, 18/3 conductor cord from the light head plugs into the electrical outlet.  The mounting arm has a 5' long, 18/3 SJTW conductor cord with a NEMA 5-15 ground plug.  All dock lights now feature an ON/OFF switch, and come complete with bulb (except DKL-INC) and wire guard.
The customer can now select from four (4) different light sources, incandescent, quartz halogen, high-pressure sodium and the NEW metal halide.  The standard duty arm or the heavy-duty triple strut dock arms which allows the customer to add a modular fan.  Whether selecting a fully assembled or a modular dock light, all dock lights are of the highest quality built products and are all UL/C-UL listed.
