Perhaps you mean LED - Light Emitting Diode

If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
Yes, LEDs are dimmable.
Basically, when LEDs are connected in parallel, the LEDs with the lowest resistance will be the brightest, the other LEDs will be dimly lit or not lit at all. Therefore, use LEDs with the same model number and colour.
Gallium nitride (GaN) LEDs are commonly used to create blue LEDs. By combining a blue LED with a yellow phosphor coating or a green and red LED, white light can be produced. Additionally, different additives can be incorporated to create other colors such as red, green, and yellow LEDs.
No.
red, green, yellow, blue leds
It depend on what the rating voltage of the LEDs are.
SemiLEDS Corporation (LEDS) had its IPO in 2010.
Most modern torches have LEDs in them, several newer models of Audis do too.
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.
LED, this is because a light emitting diode(LED) is a form of light that uses electricity and converts it into electromagnetic radiation -LEDs are therefore long lasting tech.
