Is Induction Lamp Better Than Led Light

By now, it is evident that we are facing an energy problem - while our primary sources

of energy are running out, the demand for energy is continuously increasing. In the face of this situation, energy-efficient lighting systems have become a hot topic. Energy for lighting can consume between 60% (in educational settings) and 31% (in retail store applications) of an organizations electricity budget.

As the cost of energy rises, people are seeking ways in which to reduce energy consumption. The main reason is financial, but the spectre of Global Warming (climate change) and respect for the environment by reducing CO2 emissions, also plays a role.

Here are some advantages of induction lamps compared with conventional LED lamps according to experiene of induction lamps manufacturers.

Induction lamps have a lifespan of 80,000 to 100,000 hours (depending on type and model), which is essentially almost the same as LED lamp lifespan. However, the lumen degradation will be around 14% for LED lamp after 1200 hours use because of the problem of heat dissipation. The lumen degradation of induction lamp is only 16% after 20000 hours use. Another thing is about luminous efficiency. For LED, the system luminous efficiency is around 65LM/W, while for induction lamp, it is over 75LM/W, especially for 400W induction lamp, it will be 80LM/W. The major difference between the technologies is in conversion efficiency (energy utilization) and costs.

Most presently available commercial LED lighting fixtures have conversion efficiencies in the 35 to 55 Lumens/Watt (L/W) range. LED elements with a conversion efficiency of 70 L/W are available, but still quite expensive. There are reports of LEDs with conversion efficiencies of up to 100 L/W operating in research labs, but they are not yet commercially available.

Induction lamps have a conversion efficiency ranging from 65 L/W in low wattage (8 ~ 20 W internal inductor types) to 85 L/W in the high wattage (250 ~ 400 W external inductor models) range. Ongoing research will see some small improvements in these numbers. When considering commercial/industrial lighting and using a 200 W fixture as an example, the induction lamp version will produce 17,000 Lumens while an LED version would only produce 11,000 Lumens (about 35% less light) with the same energy input.

Additionally, the higher operating frequency of Induction lamps makes the light stable and no flickering.

Above are just a few obvious advantages of induction lamps compared with LED ones.
