CIRCLE-D LIGHTS have been a leader in the field of lighting for over 60 years. Our reputation for quality is undisputed throughout the industry. We have been innovators in our designs and products, fashioning them to the needs of our users. Our units are compact in design, lightweight and extremely durable. The aluminum housing is guaranteed for the lifetime of the fixture.


The quality and sure dependability of CIRCLE-D lighting fixtures throughout the last 60 years has prompted us to initiate a refurbishing program. This is available to those of our valued customers who find that despite the years of dependable service they have experienced with their CIRCLE-D products have no need to replace their fixtures, but do want to update. This service ensures that all parts will be replaced with new and that the housing will be completely refinished. All old parts, which are still in good condition, will be returned to you and may then be used in the future, as spares. Lamps are not included in these refurbishing prices but are always available.


CIRCLE-D LIGHTS portable and permanently mounted fixtures are weatherproof, corrosion and shock resistant. Constructed of heavy wall, cast aluminum A356.2 (Aerospace quality), alloy housing with stainless steel hardware used throughout. We also use a patented, double cushioned spring mounted socket and a resilient ring rim gasket, which holds lamp tight and keeps out dirt and moisture. We are approved and listed by Underwriters’ Laboratories in the USA and Canada.
