No, that is an auto-recursive expression. The LE of LED already refers to light emitting so what you are asking about is light emitting light emitting diodes! In any case, we have no way of knowing what you want to know about LEDs.
If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
It depend on what the rating voltage of the LEDs are.
The difference is that LEDs use less electricity.
Resistors don't light up LEDs. They're required in a circuit along with LEDs in order to prevent excessive current through the LEDs when the LEDs are forward biased. The correct resistance value depends on the supply voltage and the desired (rated) current through the LEDs, and there's typically one resistor in series with each LED.
LEDs save a lot of electricity, whitch goes on your electric bills.
LEDs are a kind of light that does not run on a bulb, like a typical lamp or overhead light. Rather, it is powered by a diode that emits light. This light is brighter, clearer, and less harsh than that provided by a bulb.
The light is a series of LEDs on the edges of the display layer.

Polarized LEDs are light-emitting diodes that emit polarized light, meaning the light waves oscillate in a specific direction. This property can be advantageous in certain applications, such as displays and optical communication, where controlling the orientation of the light is important for performance.
It's surface-mount LEDs. If you know how to solder, they're green PLCC2 LEDs.
L.E.D. Stands for Light Emitting Diode so it is a Diode that makes light...
There is no such thing as a white LED. You produce white light from LEDs by combining red, green and blue LEDs. Red LEDs were produced first because red is a low frequency of light. It was the easiest to make. Green LEDs were produced next because green is a higher frequency of light. It was harder to make. By combining red and green LEDs, you can produce yellow light. Blue is a very high frequency of light and is very hard to produce. Blue LEDs and blue lasers (as in BluRay) took a great deal of effort to create. LED technology and some kinds of laser technology are very closely related.
