Understanding LED light power in Watts and LED …

LED lights by their nature are low voltage but also relatively low current making them lower in power and more efficient that traditional incandescent bulbs and halogen downlights. Generally we are talking about between 100 to 750 milli-amps depending on the forward voltage required to turn on the LED.

Top 8 Things You Didn’t Know About LEDs | Department …

Today’s LED bulbs can be six-seven times more energy efficient than conventional incandescent lights and cut energy use by more than 80 percent. 7. Good-quality LED bulbs can have a useful life of 25,000 hours or more -- meaning they can last more than 25 times longer than traditional light bulbs.

Light Emitting Diode <What are LEDs and How Do …

LEDs (Light Emitting Diodes) are semiconductor light sources that coine a P-type semiconductor (larger hole concentration) with an N-type semiconductor (larger electron concentration). Applying a sufficient forward voltage will cause the electrons and holes to recoine at the P-N junction, releasing energy in the form of light.

How Many Volts are Needed to Power an LED? - KitHub

A light-emitting diode, or LED, is an energy-efficient light source. They are small, they don’t have a filament, and they don’t get especially hot. They are also a simple enough device to include in beginner electronics projects. That’s why we included them in our classroom kits and programs!
