LED Frequently Asked Questions

LED light sources used in a residential application.

LED technology continues to develop rapidly as a general light source. As more LED lighting  products are introduced on the market, what do retailers, energy efficiency advocates, and consumers need to know to make informed buying decisions?

Are LEDs ready for general lighting?

The number of white-light LED products available on the market continues to grow, including a wide range of replacement lamps, as well as integrated light fixtures, such as portable desk/task lights, under-cabinet lights, recessed downlights, track heads, and outdoor fixtures for treet and area lighting. Some of these products perform very well, but the quality and energy efficiency of LED products still varies widely, for several reasons:

The Changing Shape of Light by Jim Axelrod, CBS News

Recently I saw this wonderful video about the need of incadescent bulbs replacement and the entry on the market of new led light bulbs. Check this video made by CBS News.

The Ultra-Slim Energy-Saving 12W FZLED Downlights with Light Guide Technology

FZLED, the leading maker of LED lighting products, today launched a new range of 12-Watt LED downlights featuring cutting-edge light guide technology. The energy-efficient, low-maintenance FZL-DL06-00 series is a simple money-saving replacement for any older 6-inch diameter downlight.

The innovative FZL-DL06-00 series introduces light guides to direct part of the LED light output to the sides. This creates a far more pleasant, balanced and gentle illumination than competing downlights, but without compromising coverage or brightness.

Samsung Launches New 10W Light Bulb with 3000K and 550lm

In regard to the replacement for 40W incandescent light bulbs, consumers can select from not only four.4W LED light bulbs but also 10W LED light bulb manufactured by Samsung. Samsungs 10W LED light bulb with E27 socket can adequately replace 40W incandescent light bulbs, but falls short compared to the luminosity of 60W incandescent light bulbs.

This new product, named Samsung LED A19, can accomplish a 75% energy conversion rate with a lifespan of 30 thousand hours, a beam angle of 180 degree, a 550lm luminous flux and a 3000K color temperature (warm white light).

Alternative Light Bulbs Improving

The light bulb aisle isn't as simple as it used to be. From CFLs to LEDs to new halogen incandescents, there are a lot of choices. With new federal regulations about to take effect, it's a good time to consider your lighting options.

New federal rules on energy efficiency take effect in January and start the official phase out of standard incandescent light bulbs. There's no need to hoard them, though. The most popular 60-watt size can be made until 2014. In the meantime, the good news is that alternatives are improving.

Choose LED Light Source From Nine Aspects

With the rush in to the led lighting field, as a consumers still needs to be quiet, scientific analysis to choose to best performance but favorable cost light source and lamp type. There's lovely aspects for consumer to pay attention to choose the right led light source, find the introduction as below:

1. Antistatic abilityIf the antistatic ability is strong, then the lifetime for led will last longer, so the price would be expensive accordingly. Normally the led light source which can be used for decoration its antistatic ability needs to be over 700V.

The advantage of LED tube light over traditional fluorescent tube light

LED tube light over Fluorescent light

LED Tube Lights are most times erroneously called LED fluorescent tubes. An LED tube light is actually an LED bulb that is designed to resemble a fluorescent tube light in its dimensions and fixture options. The similarities finish with the shape.
 

These type of lights are based on innovative solid-state lighting know-how while fluorescent tubes are powered by a know-how that is at least a generation elderly. LEDs have taken advantage of the phosphor know-how developed to help improve the performance of fluorescent tubes and have successfully leapfrogged several years worth of development that goes in to improving any lighting know-how. Today LED tube lights deliver equal or better lighting performance with only a fraction of the energy consumption of the traditional fluorescent tube lights.
