Induction Lighting

Unlike fluorescents, Econergy does not contain electrodes. This fact alone makes it outlive lamps using other technologies and create a huge impact on energy savings and reduced maintenance costs.

In addition, Econergy provides:
  • Immediate, significant reduction in electricity costs of 40% to 60% over HID lamp sources
  • Longer operating life resulting in substantial reduction in maintenance costs
  • Faster lamp starting, instant re-strike
  • Improved color and visual appearance. Color rendering index of 80 Ra
  • No flickering, high frequency operation
  • Available in 40,70,100,150 and 200W solutions
  • Environmentally friendly technology, less landfill waste

With an average rated life of 100,000 hours and very low lumen depreciation, Econergy lamps provide an impressive savings in both materials and labor costs: by the time one Econergy lamp has reached its end of life, an older metal halide lamp would have been changed 8 to 9 times. And sodium vapor lamps would have been replaced, on average, 4 to 5 times.

 

Econergy’s long operating life translates directly into substantial savings in maintenance costs
The environmental footprint of Econergy means less harmful waste on landfills. Over the life of the Econergy lighting system, a metal halide system would have contributed over 240 mg of mercury to the environment, as compared to 6 mg for induction.

Perhaps most impressive is Econergy’s watts per lumen feature. Not only does it consume less energy, but the light output is, literally, brighter.

Scotopic vs. photopic

Why do induction lights appear to be brighter even though a light meter may measure them as producing the same or even less light than conventional lamp? The reason is the contribution of scotopic vision (night vision) to the sensitivity of the eye. Scientific studies have shown the eye is more sensitive to blue wavelengths, the ones largely responsible for “visual acuity” or sharpness of vision. Simply put, induction lamps have a higher ratio of scotopic light (as compared with regular, photopic light). This ratio determines the apparent visual brightness of a light source, making the 100w induction lamp appear as bright or brighter to the human eye than a sodium vapor or metal halide of nearly twice the wattage.

Kumho Electric’s electrode-less induction lighting leverages new technology developments to provide a high-efficiency, low-maintenance, long-term lighting solution. With a 100,000-hour rated life, Econergy induction lamps are ideal for outdoor applications where re-lamping is expensive or cumbersome, as in parking lots, street lighting, tunnels, or indoors for high bay fixtures. Versatile mounting options make them the ideal choice for a variety of pole, ceiling and wall-mounted applications.

How do Econergy Lamps
Save Energy?

Typical HID lighting has steep lumen depreciation curves, losing as much as half its initial light output by the time it reaches midlife. Econergy is manufactured with technology Kumho Electric developed for the back light panel display industry, which reduces lumen depreciation to less than 30% over the 100,000-hour life of the lamp. Since HID lamps tend to be over-designed, providing higher initial lumens to compensate for fast degradation, wattage is being wasted due to expected light loss. Econergy’s high lumen maintenance levels makes this over-compensation unnecessary.

In addition, Econergy provides much higher level of luminous efficacy (lumen/watt) due to scotopic factors: high color temperature (K) combined with high color rendering index (CRI). The resulting clean, crisp white light is better to read, work and sell under. Colors are truer and merchandise looks real. This better visual acuity is achieved using less energy than with other, higher-wattage lamps.

Gradual, minimal light depreciation ensures predictable, uniform illumination over many years.

 

Slashing Maintenance Costs

Re-lamping outdoor or high-bay fixtures is both costly and cumbersome, involving specialized equipment and maintenance crews. Since Econergy lamps have a rated life of 100,00 or longer than 10 years(*), they can be expected to last four to five times longer than typical HID lamps. This means the frequency of replacement goes down to virtually zero. Econergy induction lighting will pay for itself with energy and labor savings on spot replacement and re-lamping costs alone.

NOTES:

  • Four components make up the Econergy system: lamp, power coupler, heat sink and generator
  • Approximate lumen values listed are for vertical operation of the lamp
  • Mean lumens is the approximate output at 40% of rated average life

Features & Benefits
  • Very long life – 100,000 hours rated life translates to significant savings in maintenance costs
  • High lumen output – 2,800 initial lumens
    (40W lamp) to 11,250 initial lumens (150W lamp)
  • Range of input voltage – each lamp has the ability to operate on voltages ranging from 120 to 277
  • Gradual, minimal lumen depreciation – still at 70% luminosity at end of life means fewer replacements, more efficient lighting
  • Outstanding color rendering – CRI of 80 provides for vivid, natural colors
  • Range of color temperatures – choice of warm or cool light for desired effect and particular applications

 

  • Stable output – relatively unaffected by fluctuations in line voltage, the Induction lamp output remains constant over wide ranges of inputs
  • Instant-ON capability – because it does not require warm-up time to come to full luminescence, it can be controlled by occupancy sensors to provide further energy savings
  • Hot and cold operation – performs on a wide range of environments –from -20° to 60°
  • No flickering or noise – a distraction-free option for indoor or outdoor applications
  • Low mercury – uses only 6 mgs of mercury,
    a much more environmentally-friendly product than other alternatives

Induction

 

New induction lighting makes a BIG difference . . .

THE PROJECT:  Working with Graybar electric distributor, Kumho Electric provided lighting fixture retrofit kits and induction lamps to retrofit high bay lighting in a major Midwest automotive manufacturing facility.

DETAILS: Project retrofitted 2095 high-bay fixtures, replacing 250W Metal Halide lamps with 150W Kumho Electric induction lamps.

induction cast study

 

. . . in workplace appearance and functionality

Note the yellow cast (color temperature) of the metal halide lighting in the “Before” photo. New induction lamps, provide better color rendering and brighter, clearer illumination.

. . . in energy use and electric bill savings

The retrofit cuts energy consumption almost in half with a net energy savings of about 133W per fixture or almost 300,000 watts for the plant.

. . . and in long-term cost reductions

With a rated life of 100,000 hours — more than five times longer than metal halide — Kumho’s induction lamps virtually eliminate re-lamping and lighting maintenance for over 20 years!

1st year electric bill savings: $145,000
ROI Payback: 1.71 years
