LED is not only one solution for your cost saving anymore!!

Compared with LED

  • No harsh glare
  • No multiple shadows
  • More widely spread and uniform lighting overall in space
  • The weights does not give stresses to ceiling structures




Compared with Mercury Lamp

  • Outstanding energy saving : 1/4`1/5
  • Higher color rendering index : Ra80 vs Ra40
  • Long life for 100,000 Hrs : 5`8 times
  • Instant Start and Hot Re-strike
  • Return on investment in 1.38 years only

Comparison between iEL and other Induction lights

Ball type realizes an ideal and higher efficient light reflection than Circle type.

Circle typeBall type induction lamp
Circle type induction lamp Ball type induction lamp
Each light is clashing inside the circle and affects its efficiency.
  • Ball type design provides omnidirectional lights
  • Specially processed reflector by German manufacture realizes high efficiency irradiation, 96.7%
  • 135 kHz frequency for better energy efficiency

Lighting Mechanism




An Induction Lamp is similar to a fluorescent lamp in that mercury in a gas fill inside the bulb is excited, emitting UV radiation that in turn is converted into visible white light by the fluorescent coating on the inner surface of the bulb. Fluorescent lamps, however, use electrodes inside the bulb to strike the arc and initiate the flow of current - each the arc is struck, the electrodes degrade a little, eventually causing the lamp to flicker and then fail. Induction Lamps differ in that they do not use internal electrodes, but use a high-frequency generator with a power coupler. The generator produces a radio frequency magnetic field to excite the gas fill.
