Light-Emitting Diode (LED)

An LED lamp (LED light bulb) is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. LED bulbs stocked at LBU are tested strenuously to verify tough standards 50,000 hour life and 5 year warranty. If a company is selling an LED and claiming 50,000 hours and only a 3 year life you may want to inquire further…

Lumens and kelvin are much more important than wattage. We started with a simple retrofit light bulb so avoid changing cans and saving you money. Indoor, outdoor (parking lot lights) commercial mr16, mr11, tape light (solid or rgb) and over 10,000 light bulbs in stock.

We have an LED bulb most every use and there are a lot of options when switching to LED.

Since the light output of individual light-emitting diodes is small compared to incandescent and compact fluorescent lamps, multiple diodes are often used together. In recent years, as diode technology has improved, high power light-emitting diodes with higher lumen output are making it possible to replace other lamps with LED lamps. One high power LED chip used in some commercial LED lights can emit 7,527 lumens while using only 100 watts. LED lamps can be made interchangeable with other types of lamps.

Compared to fluorescent bulbs, introduced at the 1939 World's Fair, advantages claimed for LED light bulbs are that they contain no mercury (unlike a Compact fluorescent lamp or CFL), that they turn on instantly, and that lifetime is unaffected by cycling on and off, so that they are well suited for light fixtures where bulbs are often turned on and off. LED light bulbs are also less apt to break.

White-light light-emitting diode lamps have the traits of long life expectancy and relatively low energy use. The LED sources are compact, which gives flexibility in designing lighting fixtures and good control over the distribution of light with small reflectors or lenses. Because of the small size of LEDs, control of the spatial distribution of illumination is extremely flexible and the light output and spatial distribution of a LED array can be controlled with no efficiency loss.

LED lamps have no glass tubes to break, and their internal parts are rigidly supported, making them resistant to vibration and impact. With proper driver electronics design, an LED lamp can be made dimmable over a wide range; there is no minimum current needed to sustain lamp operation.

LED lamps intended to be interchangeable with incandescent lamps are made in standard light bulb shapes, such as an Edison screw base, an MR16 shape with a bi-pin base, or a GU5.3 (Bipin cap) or GU10 (bayonet socket). LED lamps are made in low voltage (typically 12 V halogen-like) varieties, and as replacements for regular AC (e.g. 120 or 240 V AC) lighting. Many LED lamps have become available as replacements for screw-in incandescent or compact fluorescent light bulbs.

A Case for Retrofitting: LED vs. MR16 / MR20

MR16 and MR20 lamps have long been the desired light source for outdoor, interior track, recessed, retail display and other commercial or residential lighting. However, here are some benefits of changing to LED:

  • LED provides major improvements that trump the efficacy of standard halogen
  • Longer lamp life means less maintenance costs
  • Cooler operation means less heat damage to the fixture, socket and housing
  • Choice of color temperatures and beam spreads is much greater
  • Much lower wattage saves energy and maintenance costs making it more “green”

Using them is as easy as switching out your halogen lamp for Light Emitting Design's LED Retrofit lamp.
