Induction Lamp vs LED
- Nikola Tesla invented induction lighting in 1891. It is a proven, refined lighting technology, established as highly energy efficient. (Nikola 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 1 to 2 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 lighting. LED has to be "domed", needing many LEDs to create the effect of area lighting. This factor is expensive and more vulnerable to premature technical failures.
- Induction Lighting has a rated life of 80,000 - 100,000 hours.
LED has a rated life of 30,000 – 50,000 hours.
- Induction is warranted for 5 years.
LED has a shorter warranty of 1 to 3 years.
- Induction lighting can maintain output from – 50C to + 100C degrees.
LED has a seriously reduced output (lumen depreciation) above 25C degrees. Most lights are that hot in an enclosed fixture with just spring/summer ambient temperature. (See the CREE article on temperature).
- An induction, 200 watt bulb is rated at 33,320 "visible" lumens.
A LED, 200 watt bulb is rated at 17,520 "visible" lumens, a 15,800 Visible Lumens difference.
Induction Lighting is a better choice for any area, lighting application. Please see our products list and call or email for pricing. Bemi Lighting is a distributor of quality induction products and can retrofit your fixtures in most cases or install new as needed.
