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 can maintain output from - 40F to + 122F degrees.
LED has a seriously reduced output (lumen depreciation) above 77F degrees. (Most lights are that hot in an enclosed fixture with just spring/summer ambient temperature). (See the CREE article on temperature)
Induction lighting has an efficiency rating of up to 96 lumens per watt. (100w comp. street lamp)
LED has an efficiency rating of 37-50 lumens per watt. (135 watt street lamp)
Induction: 200 watt bulb is rated at 16,000 "seeable" lumens.
LED: 200 watt bulb is rated at 11,000 "seeable" lumens.....a 31% (less) difference.
Induction Lighting is a better choice for any area lighting application. Please see the products list and call or email for pricing. Carolina Induction is a distributor of quality induction products and can retrofit your fixtures in most cases or install new as needed.
