Incandescence technology has long proven to be reliable, easy to use and a part of a cozy and inviting environment. Incandescent lamps are a design element in themselves, require no external regulating equipment, have a low retail cost, keep their environment warm, reducing heating costs and they work well on either alternating current or direct current and any dimming systems.
