Technical data

LED is Light Emitting Diode

LEDs must be connected in the correct way,the diagram may be labelled+ for anode- for cathode.LEDs is the future of the lighting field.

Advantages

1- Economy.The use of LED lighting can offer significant cost saving over timebecause LEDs run on low current & low voltage and efficientlyconvert electricity into light.Also require less energy to manufacture than other light sources.

2- Environmentally friendly (green products).Low energy than standard bulb.No ultra- violet.No Infrared

3- Improved safety & security.Low heat generation that reducing the load on the air condition.Low voltage so it is safety with children's & also eliminates sparks.

4- Long life span.With an expected life span from 50.000 hr to

100.000 hr (approximately from 6 to 11 yearsfor continuous use)
