Induction lighting is a great alternative to traditional high bay metal halide & sodium vapor lighting.
One of the main advantages is the lower running cost, in many applications over 50%.

Differences between Induction Lighting & Metal Halide Lighting
- Induction Lighting has a bulb life of up to 100,000 hours & it's not sensative to operating position. Metal Halide Lighting typically lasts 10,000 hours when they're in the vertical position, however most bulbs are in the horizontal position and must be reduced in rating by approximately 20% (8,000 hours)
- Induction Lighting has a running tempereture of 48 - 74 degrees Celcius, while Metal Halide Lighting has a tempereture of 232 - 482 degrees Celcius.
- Induction Lighting has slow lumen depreciation & can maintain up to 70% of original lumens for 60,000 hours or more. Metal Halide has fast lumen depreciation & can lose 5% of it's lumens in the first 200 hours & 20% lumen loss every 2000 hours (5-6 months)
- Induction Lighting has a consistent crisp blue-white light throughout it's lifespan. Metal Halide experiences color shifting as it quickly ages.
- Induction Lighting is instant-on & instant re-strike which eliminates warm up periods. Metal Halide has a 10 minute warm up period.
- Induction Lighting has a high CRI (Color Rendering Index) of 90+ which improves vision recognition. Metal Halide has a CRI rating on 65.
- Induction Lighting is nearly maintenance free for the rated life of the bulb/ballast & has a 5 year warranty. Metal Halide is high maintenance & has no known warranty.
- Induction Lighting has a high visual acuity (visible) lumens per watt of 191. Metal Halide has a visual acuity lumen rating of 80 per watt.
- Induction Lighting is better for the enviroment, as it uses a solid amalgam (dental mercury form) of only 1.5-6.5 mg, which can be easily handled and recycled as well as other parts of the light. Metal Halide uses 30-50 mg of mercury and requires special handling. Using Metal Halide means 8-10 times more hazardous waste to deal with because of more bulbs to replace versus induction & it is NOT in a solid amalgam form.
