LEDs: The lightsource of the future
What makes LEDs so special?
The advantages of the LED torch speak
for themselves:
– up to 5x brighter light output
– up to 10x longer battery runtime
than conventional incandescent bulb torches .

Measures of Comparison
– Millimeter: Indicates the size of the LED in diameter.
– Watts: Measures the electrical power consumption by a light.
– Lumens: Most dependable measure of a light’s true output.
The “standard” in light output.
– Lux (lx): Measure of the illuminance, shows how many lumens per square
metre are reaching a certain surface. The Lux value is the most common
known photometric unit and indicates very clearly the lighting condition at
a special point.
– Candela (cd): Unit of the luminous intensity. It’s the power emitted by a light
source in a particular direction. A common candle emits light with a
luminous intensity of roughly one candela (=1 lx in distance of 1 meter).
