| Benefits of ETL Induction Lamp |

Eco-friendly lighting

• eco-friendly low mercury lamp (mercury content is below 6mg)
• minimization of various waste treatment cost and discharge of pollutant source due to long lifetime

Minimization of overgrowth of plant
minimization of crop damage

Reduction of maintenance cost due to long lifetime
It can be used over 16 years when used 10 hours per day.

• General duration : 100 thousand hours (up to 55% compared to initial luminous flux)
• Effective duration : 60 thousand hours (up to 70% compared to initial luminous flux)

Sharp reduction in energy use
45% of power save compared to existing discharge lamp

• Three-wavelength high efficiency lamp (above 80lm / W)
• High efficiency Ballast (the power factor is above 96%)

High color rendition
- Color rendering similar to natural color is realized as a three-wavelength lamp (above 80Ra)

Instant light-up and re-lighting
Light-up and re-lighting time is below 0.01 second.

Minimization of eye fatigue
It minimizes eye fatigue as it does not flicker due to its high frequency drive and has low luminance as a surface light source.

Low value Temperature (Campared to existing discharge lamp)
It enhances air-conditioning efficiency and prevents fire due to its temperature below 90 degree during the lighting

| Principle and Structure of Induction lamp |

• Ferrite core is built outside the bulb rather than inside electrodes (filament, glow tube)
• Special inverter with which high frequency (250kHz) oscillating to ferrite core is possible Energy is supplied from (electronic Ballast for Induction lamp)
• Ultraviolet is generated as Electromagnetic field occurs in lamp and it responds to filled gas inside the bulb.
• Generated UV ray passes through three-wavelength fluorescent materials coated on inside the bulb and finally it is emitted as visible rays.
• Innovative lighting system of long duration, high efficiency and high color rendition

Energy reduction effect due to enhancement of system efficiency
Induction lamp has benefit of enhancing the efficiency of lighting fixtures by applying high illumination reflectors as its features are similar to fluorescent lamp.
Therefore, it is possible to substitute lamps whose quantity of light is relatively high. 45% of energy reduction compared to metal Halide.

Energy reduction effect due to luminous flux maintenance factor
In case of Induction lamp, average illuminance according to operation of the whole lighting system can be maintained similarly or higher by exchanging Sodium and metal Halide lamps whose Luminous flux are decreased fast for Induction lamps having quantity of light below certain level since Induction lamp maintains above certain level ofLuminous flux for a long time due to its long Lifetime.

Energy reduction effect due to improvement of color rendition
Induction lamp has high visibility even in a low Ilumination due to its high color rendering. Thus, energy can be saved by designing low-capacity Induction lamp and it prevents fatigue of eye and crimes.

Features of Light Source and Brightness Ratio
Induction lamp system gives brighter feeling than other lamps due to the features of light in the same illumination. For example, illumination design of metal Halide lamp and high pressure Sodium lamp should be higher than that of Induction lamp system by 25% and 52% ,respectively, in order to give the same visual acuity.
