It's surface-mount LEDs. If you know how to solder, they're green PLCC2 LEDs.
If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
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.
red, green, yellow, blue leds
No.
It depend on what the rating voltage of the LEDs are.
Most modern torches have LEDs in them, several newer models of Audis do too.
SemiLEDS Corporation (LEDS) had its IPO in 2010.
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.
The difference is that LEDs use less electricity.
There are 16 LEDs in the headset
LEDs save a lot of electricity, whitch goes on your electric bills.
