What are the advantages of led light units compared to tungsten light units?
They use less power and don't give off so much heat.
What are LED advantages and disadvantages?
Advantages - efficacy, they produce more light per watt verse a regular bulb. Disadvantage - cost, for reasons why they are better, they cost more. Color is much crisper and emits less energy to project although the work best in a temperature controlled environment so if the temperature fluctuates then the life of the bulb is lessened. LED doesn't contain mercury which is a toxic substance used in fluorescent lamps. Although the blue light LED's emit can cause light pollution and even possibly cause eye damage.
Where is there a resister in a light bulb circuit?
In an old-fashioned light bulb, the part that emits light is a resistance. When current flows through it, it heats up so much that it glows - it emits light.Due to their lousy efficiency, these light bulbs should be discarded, in favor of fluorescent light bulbs or LED light bulbs.In an old-fashioned light bulb, the part that emits light is a resistance.

How much energy is needed to heat 0.5 kg of LED?
LED is an acronym for Light Emitting Diode, so I assume the metal LEAD was intended. This question has been answered extremely well.
How much does a brake light bulb cost for a corsa envoy 1.2?
I think this is your vehicle (see related link) so you need 380 type bulb. A basic filament bulb costs from £1.28, An upgrade LED type bulb costs from £8.20
Who invented the first LED light bulb?
Thomas Edison invented light because he made light so why not bulbs
How much does it cost you to burn a 0 watt light bulb for 24 hours a cost of 0.085156 per kwh?
A 0 Watt bulb does not consume electric power so the cost is zero.
What are the different color spectra of a LED?
A single LED emits light at one single frequency, so it has no spectrum.
Can you replace a 60 watt incondescent light bulb with a 100 watt CFL?
You will have more light but at a lower cost. They produce much less heat so that wouldn't be a problem.
What is an LED TV, and why is it different from normal televisions?
An LED TV is just simply a TV with a backlight. The term LED stands for light emitting diode. This TV's give a much better picture than the old style televisions so that you can choose the best option for you.
Why should you change away form using incandescent light bulb?
There are other forms of artificial light devices that consume much less power, and generate less heat, such as Halogen, LED, and so forth.
Are LED maglite brighter than maglite?
Well they are suppose to give off the same light, say in wattage, but they use less power, and generally cost more. Most LED's, have a rating to match a regular bulb. Say, a led flashlight, is marked as equal to a 50w bulb. On the maglight website, they do not list wattage or lumens , so you have to assume that both mini mags are equal in light produced.
