Q: How does induction lighting lower my electric utility bill?
150W induction lights use significantly less electricity than 400W or 320W metal halide or other high intensity discharge (HID) lights.
Q: How do induction lights result in lower fixture, ballast and maitenance costs?
Since induction lights have a rated life expectancy of 60,000 to 100,000 hours versus a 10k to 12k hour rating for metal halides, induction lights will require replacement much less frequently. Savings result from not having to pay for the labor involved in bulb replacement. This can be a significant amount, especially for hard to reach fixtures.
Q: How do induction lights achieve such a long life?
The primary limit on the life of light bulbs are the electrodes and filaments. Induction lamps use neither electrodes nor filaments.
Q: How does induction lighting Increase brightness of lighting fixtures?
All lighting loses brightness over time - this is known as Lamp Lumen Depreciation. Metal halides lose brightness much more rapdidly than induction lights. Therefore, induction lights provide more light, that is more lumens, than metal halides over time.
In addition, the light color of induction is much whiter than the yellowish color range of metal hanlides and high pressure sodeium, providing a quality of light much closer to noon sunlight.
Q: Are inductions lights new technology?
Induction lights have been marketed commercially since 1990 and their origin dates back to Nikola Tesla in the 1890's. This Wikipedia article provides a history of induction lighting: Induction Lighting article
Q: How does an Induction light compare to a metal halide?
| Induction | Metal Halide | |
| Instant On/Off | Yes | No |
| Lumen Maintenance | 90% after 20k hours | 70% after 4.6k hours |
| Heat Generation | Lower | Higher |
