Induction: Tesla invented induction lighting in 1891, is proven, established as energy efficient and refined. (Tesla also invented AC current)
LED is still under much technical revision and unproven in high power lighting applications.

Induction lighting is a cost effective solution as a new purchase or as a retrofit with a 2 to 3 year ROI when considering energy and maintenance costs. (Without energy rebates or tax incentives)
LED is energy efficient..... but with a 4 to 5 year ROI. (Currently costs nearly twice as much as Ind.)

Induction Lighting is designed for area lighting and does not need to be specially designed for that purpose.
LED is designed for directed/spot lightiing and has to be "domed" with many led's to create the effect of area lighting...which is expensive to make and more vulnerable to premature technical failures.

Induction Lighting has a rated life of up to 100,000 hours.
LED has a rated life of only up to 50,000 hours.

Induction is warranted for 5 years. LED has a shorter warranty of 3 years.

Induction has broad product choices. LED has limited choices of products.

Induction has product standardization. LED has no standardization in their technology as yet.

Induction Lighting has a bulb life rating of up to 100,000 hours. ( up to 22.5 years/12 hour days) And not sensitive to operating position.
Metal Halide typically most bulbs are rated at 10,000 hours. (In the vertical position) Most bulbs are in the horizontal position and must be reduced in rating by approx. 20% (8000 hrs.).

Induction Lighting has slow lumen depreciation (light loss) and can maintain up to 70% of original lumens for 60,000 hours or more.
Metal Halide has a fast lumen depreciation (light loss) and can lose 5% of its lumens in the first 200 hours...and 20% lumen loss every 2000 hours (5-6 months) thereafter. Burning 400w of power but getting 200-225 watts of light at the end of year one. Not very efficient.

Induction Lighting is nearly maintenance free for the rated life of the bulb/ballast and has a 5 year warranty.
Metal Halide is high maintenance and has no known warranty.

Induction Lighting has a bulb life rating of up to 100,000 hours. (up to 22.5/12hr. days)
HPS is rated for 20,000 hours.

Induction Lighting has slow lumen depreciation (light loss) and can maintain up to 70% of original lumens for 60,000 hours or more.
HPS has fast lumen depreciation similar to metal halide. Bulb life is twice as long as metal halide. This is why it may be chosen as an alternative to metal halide in high reach areas. It is just not the best choice.

Induction Lighting is nearly maintenance free for the rated life of the bulb/ballast and carries a 5 year warranty.
HPS takes more maintenance and has no known warranty.

Induction Lighting has a high color rendering index (CRI) of 80+ . This makes colors much more vivid.
HPS has a low CRI of 20 - 22. This is why colors are so hard to see with this intense "yellow" light.
