Induction Lighting Pros as Hangar Lighting article Hangar Network eNewsletter March 2014

The most common complaint we hear from those who work in aircraft hangars is that there isn’t enough light to do mechanical repairs, closely followed by grievances about always having to change out bulbs and ballasts on 35′ ceilings. 

Replacing traditional Metal Halide High Bay fixtures with Induction High Bays may be the answer to these Induction Lighting Pros as Hangar Lightingcomplaints. Here’s why: 

(1) Lumen depreciation (Light Loss Factor): The most common cause of lumen depreciation is heat, so the hotter the bulb burns, the faster it loses its light. Metal Halide bulbs burn at extremely hot temperatures and need replacement after every 2-5 years. Induction lighting, on the other hand, has a much cooler burn temperature -The Neptun Light Induction bulbs are rated for 100,000 hours of operation, so that means that only after 70,000 to 80,000 hours of lighting will the bulbs depreciate. Moreover, that means you will have 15- 20 years of light (if we’re talking 12 hour work days). 

(2) Color Rendering Index (CRI): CRI is the ability of the light source to illuminate colors and details effectively. Metal Halide lights have a CRI of 65, while Induction Light sources typically have a CRI of 86. This difference allows for a significantly better visual effect. 

(3) Photopic and Scotopic Lumens: Photopic Lumens refer to the total amount of light coming from a light source, including ultraviolet light, which the human eye cannot see, while Scotopic lumens refer to the visual lumens that the eye can see. Induction light emits very little ultraviolet light so most of the lumens are actually visual lumens (not the case for Metal Halide lamps). 

The final advantage to Induction lighting is the fixture warranty. Neptun Light, Inc. offers a 10-year warranty on all of their Induction Fixtures and a 5-year warranty on Induction Bulb/ballast retrofits for existing fixtures.
