Led Light Fixtures
There comes a time when change just needs to happen. Just about every home has a dozen or more light fixtures made for medium base incandescent bulbs. Those fixtures have served for many years; but there are good reasons to replace them with LED light fixtures. LED light fixtures can be made in shapes impossible for lights designed to accommodate traditional light bulbs; or they can be made to fit just the same spaces as their counterparts. They use less energy, produce less waste heat, and last many times as long.
LED light fixtures can take advantage of the small size of LED’s. As LED’s become more common, look for LED light fixtures to come in an increasing variety of shapes new to the lighting world. One available desk lamp has a 10” long triangular light bar with half a dozen LED’s giving an even illumination from a space the thinnest fluorescent tube couldn’t possibly fit into. Some under cabinet LED light fixtures are less than ½” thick, and hide invisibly behind the lip of a kitchen cabinet.
Many LED light fixtures for ceilings look like, and fit into, the same spaces as their incandescent and fluorescent counterparts, but can be made much shallower. One common LED ceiling light is 7” in diameter, yet just ½” thick. There are LED fixtures to take the place of standard can lights, LED troffers (lights made to fit modular drop ceilings) and a variety of recessed LED lights, both pivoting and fixed, floodlight and spotlight.
Heat decreases the life of LED’s, and changing 120 volt household current into the 12 or 24V an LED requires produces a significant amount of waste heat. This is why many LED replacement bulbs have large cooling fins in the base. LED light fixtures can address the heating problem in a more efficient way by putting the driver or transformer into a box completely separate from the lights themselves, and thereby keeping that heat source separate as well. It also means the LED light fixture itself can be made much more compact and thin than if the driver were part of it.
An investment in LED light fixtures is repaid in full. The lower energy cost adds up, and the long life of LED’s lets that savings add up for many years. You can expect about 50,000 hours of useful life from a LED light fixture.
The advantages of LED light fixtures are compelling. Energy savings and long life result lower long term costs. The small size of LED’s allows slender LED light fixtures to be installed in places previously impossible; and is beginning a new era in light design. Get ready for fixtures to assume shapes you never thought possible.
