LED = Light Emmitind Diode
Products have (use) LED's if they are designed to give off light AND
the designer wishes to save power (or possibly to reduce heat).
Super Bright LEDs offer a full line of high quality LED lighting products for a variety of applications including Automotive, Recreation, Boating, Landscape, and Home. Some products they offer are car headlight bulbs, trailer lights, accent lighting, industrial lighting, strobe lights, flashlights, and motorcycle lights.
If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
Lumex is a leading company that manufactures optoelectronics products. The following are some of its products; TitanBrite High power LEDs, InfoVue LCDs, and SunBrite General Illumination.
The company Lasertechnik offer a range of products and services in electronics. Products include laser diodes, LEDs, detectors, optical devices and other accessories.
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.
No.
red, green, yellow, blue leds
Most modern torches have LEDs in them, several newer models of Audis do too.
It depend on what the rating voltage of the LEDs are.
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.
