Types of LEDs

Diffused bulbs

In this style LED bulb, clusters of LEDs are covered by a dimpled lens which spreads the light out over a wider area. Available in standard Edison bases, these bulbs have many uses, such as area lighting for rooms, porches, reading lamps, accent lamps, hallways and low-light applications where lights remain on for extended periods.

Diffused high power bulbs

Designed for standard household use, these bulbs produce light equivalent to a 100-watt incandescent bulb. The EvoLux and ZetaLux are the first UL Listed and FCC approved LED light bulbs for general household illumination.

Track Lighting

Available in MR-16 (pin base), LEDs are ideal for track lighting. LEDs do not contribute to heat buildup in a room because no matter how long they remain on, they do not get hot to the touch. Also, because they are 90% more efficient than incandescents, and last 10 times longer than CFLs, the frequency of changing bulbs is greatly reduced.

Recessed Downlight and Spotlight bulbs

LEDs are now available for standard recessed lighting pots and housings. The light output and color quality are similar to incandescent downlights, but draws only about one-fifth of the power. Also, because they are 90% more efficient than incandescents. and last 10 times longer than CFLs, the frequency of changing bulbs is greatly reduced.

Outdoor Floodlight LEDs

Typically, security lights and outdoor floodlights use energy sucking halogen bulbs. Some people use CFL bulbs instead, and find they die quickly if installed in motion -activated switches. LED bulbs are great replacements: they are energy efficient, and will last up to 50,000 hours even when flicked on and off frequently. However, they are not as bright as halogen bulbs.

LED Colors

Red - red is the traditional color for maintaining night vision.

Green - green is now the preferred color for pilots and the military. The green color is also great for retaining night vision, and it doesnt erase the red markings on maps and charts.

Blue - many people like the blue because it is very easy on the eyes. Blue appears to be a good reading light for elderly eyes. Elderly folks report that they can read under the blue light for hours without eyestrain, compared to severe eyestrain in less than 30 minutes with incandescent lighting.

White - the most popular of the LED colors. It produces a soft white light, without harsh reflection, glare or shadows.

Amber - LED amber bulbs do not attract flying insects, as do ordinary white bulbs. Amber LEDs are used outdoors in areas such as patios and decks where insects flying around lights are a nuisance.
