How Induction Lighting Works



The basic technology for induction lamps is not particularly new. Essentially, an induction lamp is an electrodeless fluorescent. Without electrodes, the lamp relies on the fundamental principles of electromagnetic induction and gas discharge to create light. The elimination of filaments and electrodes results in a lamp of unmatched life. Lasting 100,000 hours or 25 years, this system can outlast 100 incandescent, five HID, or five typical fluorescent lamp changes.

Based on these well-known principles, light can be generated via a gas discharge through simple magnetism. Electromagnetic transformers, which consist of rings with metal coils, create an electromagnetic field around a glass tube which contains the gas, using a high frequency that is generated by an electronic ballast. The discharge path, induced by the coils, forms a closed loop causing acceleration of free electrons, which collide with mercury atoms and excite the electrons. As the excited electrons from these atoms fall back from this higher energy state to a lower stable level, they emit ultraviolet radiation. The UV radiation created is converted to visible light as it passes through a phosphor coating on the surface of the tube. The unusual shape of an induction lamp maximizes the efficiency of the fields that are generated.
Although it is not breakthrough science, until recently, it has not been so commercially viable. New developments have broken down the barriers of costs and technological setbacks, such as EMC interference, lumen depreciation, ability to dim and a useful range of available wattages. Today, its obvious benefits make it the clear-cut choice for many lighting applications over traditional light sources.


Better Across the Board
Whatever aspect of lighting that you prioritize, LVD induction lamps are superior in many categories. Energy efficiency, life, color rendition, lumen depreciation, waste/heat output, glare... the list goes on. LVD lamps are truly the next generation of electric light that is set to displace several existing forms of electric lighting.
Below we have listed most of the benefits of LVD lamps. It is not an all encompassing list but you will see that they are the superior choice for many applications.

  • Higher light output – 80 lm/W vs 60lm/W
  • Lower frequency – 210kHz vs. 2.65Mhz
  • Greater range of wattages available
  • More color temperatures available
  • Frequent switching – no affect on life

LVD vs Fluorescent Lamps
  • Longer life – 100,000 hours
  • Similar energy efficency of T8 & T5 HO
  • No flickering or strobing
  • Size – LVD Venus more lumens than CFL
  • No electrodes – no on/off impact on life
  • Low maintenance – 1 LVD lasts as long as:
  • 8 HO replacements
  • 6 T8 replacements


LVD vs Metal Halide Lamps (MHL)
  • Instant on / re-strike
  • 5-10x longer life than Metal Halide Lamps

LVD vs Incandescent Lamps
  • 20x the rated life
  • Clearly better energy efficiency
  • Less glare
  • Less heat and CO2 output
LVD Induction Lamp Benefits
Low Total Cost of Ownership

Less Energy
  • 70% energy cost savings vs. HID lamps, similar to new high energy saving fluorescent lamps
  • Low heat output reduces electric cooling costs
  • Electronic IC ballast allows dimming (coming soon) which lowers energy consumption

Less Maintenance

  • Longer life means reduced re-lamping costs – In some cases zero maintenance
  • Great for hard to reach and busy areas like tunnels, roads, highbay areas
  • High and low operating temperature good for emergency use and extreme climates

Better Health, Safety and Environment

  • No flicker and less glare provides maximum eyesight protection
  • Crisp white light, choice of color temperatures – Increases safety, productivity and performance
  • Outstanding color performance – no shift over lamp life
  • Less CO2 output and mercury waste to dispose
