If you are looking to save energy and cut down on maintenance time, then LED is right for you! LED fixtures can be found in two main categories: Integrated fixtures have no bulbs or sockets and will have the Light Emitting Diodes built in as a module; legacy fixtures have sockets and come lamped with LED bulbs, or can be fitted with LED bulbs at a later date. Integrated fixtures often have a higher lumen (visible light) output and longer rated lifespan than their legacy counterparts, since the module was made specifically for the fixture. Modern LEDs are available in warm or cool color temperatures, as well as dimmable, so you can combine comfort and efficiency.
