This means that the battery in a LED torch will last a lot longer than in a xenon or halogen torch. Such are the green light on your monitor, which tells you it is on.

LED's have changed dramatically over the past few years.

I was looking for a good torch to add to my tool collection, and after looking at the Maglite range with their LED conversion kits I found the Led Lenser. It should be noted that high-power (&Emergency Light Manufacturers8805; 1 Watt) LEDs are necessary for practical general lighting applications.

For years, traditional incandescent bulb flashlights have provided limited illumination, dark spots and lighting for only short periods of.

An LED is a special type of diodes that emit light when power is running through them. If you have looked around for a torch recently you will have noticed the Spotlight current buzz in the world of torches is the LED Lenser.

The LED Torch has truly revolutionized portable lighting. LED Lenser flashlights feature superior quality optics & use only the finest materials. LEDs are much brighter and have a longer life span than standard flashlight bulbs.. This makes blue and white LED's much more expensive than the other colours.

One fantastic thing about LEDs is how long they last. They have a lifespan of over 10yrs of continuous use. Usually are indicator lights.

The white LED torch provides a similar light output to its incandescent bulb counterpart yet uses far less current from the battery. They also draw a small amount of current, usually below 40 milliamps. Hand-held torch with 128 LEDs combine to generate an impressive light source.I am a bit of a torch freak, always looking for the brightest, smallest and most efficient models. They are far, far more powerful than they used to be and are now available in practically any colour under the sun, not just that grubby green colour on the front of your monitor. Let us shed a little light on the subject.

A single LED can produce only a limited amount of light, and only a single colour at a time.

LED's are usually used in consumer electronics.

The best luminous efficacy of an OLED so far is about 10% of the theoretical maximum of 683, or about 68 lm/W. To achieve the effect of white light, three approaches can be used: Wavelength Conversion, Colour Mixing, and most recently something called Homoepitaxial ZnSe. Now this torch uses Light emitting diodes (LED) instead of the more usual Bulbs. So the burning question is what the LED can do for me. Led technology represents one of # the most fascinating future light sources: it can be modelled in a thousand different ways, through colour and light intensity, ideal for both the industrial and architectural markets, for urban and many other applications. LED's for the most part run at low voltages usually between about 1 and 4 volts. Until recently white and blue light (the most practical colours) have been hard to produce. The light is also whiter than halogen or xenon bulbs, and the beam more usable, as makers often cluster several LEDs together to illuminate a wide area
