And why should it not be overlooked?

What is induction lamp?

The basic technology for induction lamp is not particularly new and has been around over 100 years . Essentially, an induction lamp is an electrodeless fluorescent. Without electrodes, the lamp relies on the fundamental principles of electromagnetic induction and gas discharge to emitting UV radiation that in turn is converted into visible white light by the phosphor coating on the bulb. 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.

How does induction lamp work?

External magnetic induction lamps are essentially fluorescent lamps with electromagnets wrapped around a section of the lamp tube. High frequency energy, from the electronic ballast (generator), is sent through wires, which are wrapped in a coil around the ferrite inductor, creating a powerful magnet.

Induction coil produces a very strong magnetic field which travels through the glass and excites the mercury atoms in the interior which are provided by a pellet of amalgam (a solid form of mercury). The mercury atoms emit UV light and, just as in a fluorescent tube, the UV light is up-converted to visible light by the phosphor coating on the inside of the tube. The system can be considered as a type of transformer where the inductor is the primary coil while the mercury atoms within the envelope/tube form a single-turn secondary coil.

Ultra-Long Life

Due to the lack of electrodes Induction systems typically have a rated life of 80,000 to 100,000 hours depending on the light model, making them the perfect choice for hard-to-reach indoor or outdoor applications.

High Efficiency

Induction lights are environmentally friendly as they use less energy, and generally use less mercury per hour of operation over conventional lighting due to their long lifespan. The mercury is in a solid form and can be easily recovered if the light is broken, or for recycling at end-of-life. These benefits offer cost savings of around 50% in energy and maintenance costs compared to other types of lighting that they replace.

1. Very high energy conversion efficiency of between 72 and 90 Lumens/Watt (higher wattage lights are more energy efficient).

2. High power factor due to the low loss in high frequency electronic ballasts which are 98% efficient. Minimal lumen depreciation (declining light output with age) compared to other lamp types as filament evaporation and depletion is absent.

3. ”Instant-on” and hot re-strike, unlike most conventional lamps used in commercial/industrial lighting applications (i.e. Sodium and Metal Halides).

Low Total Cost of Ownership

Reduced energy and maintenance costs make induction lighting a practical solution where large areas of illumination are needed.

Outstanding Colour Performance

Induction lighting produces high quality light in a variety of colour temperatures. There’s no shift over lamp life, high 80+ colour rendengri.

High Reliability

Instant hot and cold start-up and re-start. Because its light output is not significantly influenced by ambient temperature, the induction light can start at very low temperatures, maintaining at least 85% of nominal lumens.

Stable Light Output

Relatively insensitive to line voltage fluctuations, its light output remains constant over a wide range of fluctuating input voltages.

1. Why Choose Induction Lights?

1. Maintenance

With over 100,000 hours of life, induction lamps are highly reliable and practically maintenance free. In most cases, this saving alone will more than offset the initial cost of the induction system.

2. Efficiency

Producing 150 pupil lumens of light for each watt of energy, induction lamps offer energy savings of 50%, compared to conventional sodium/metal halide.

3. Brightness

Offering crisp white light with a CRI index of 80+ and a choice of 2700K, 3500K, 5000K and 6500K colour temperatures, this makes colours appear brighter and more vibrant.

4. Instant

Induction lamps respond instantly to being switched on or off, with no lengthy waiting times.

2. What is the induction light system and how does induction lighting work?  

The induction lamp uses revolutionary light technology that combines the basic principles of induction and gas discharge. Induction technology avoids the use of electrodes, which allows for an unprecedented 100,000 hours of high quality white light.

3. Do induction lights need a dedicated fixture?

Induction lights and ballasts can be fitted into existing fixtures and housings. Please ensure that the existing reflectors are in good order otherwise we cannot guarantee lumen output.

4. What are the components of the system?

The system comprises of three components:  the ballast, the magnetic rings and the lamp tube.

The magnetic rings transfer energy from the high frequency ballast to the discharge gas inside the glass tube, using an antenna that contains the primary induction coil and its ferrite core.

The rings also have a heat–conducting rod with a mounting flange which allows the induction lamp system to be mechanically attached to the luminaries.

5. Can induction interfere with computers, telecommunications or other electronic Device?

No. Induction systems run at 250 kHz which complies with FCC and CE (EMC) Regulations with non–interference under normal circumstances.

6. Is the light output of an induction lamp affected by temperature?

The lamp amalgam fill technology and the heat–conduction rod in the centre creates a stable light output over a wide temperature range maintaining at least 85% of normal lumen output from -40°C and +40°C.

7. How long will the Induction lamp last?

Induction lighting systems are designed to have an average rated life of 100,000 hours at a maximum ballast case temperature of 65°C.


-external systems (Separate ballast) – 100,000 hours

-internal systems – (Separate ballast) – 80,000 hours

8. What is the typical Lumen maintenance?

The lumen output of the induction lamp is expected to depreciate after 80,000 hours to 80% of the initial rated lumens (or 20% lumen depreciation).

When a fluorescent lamp is new its light output is at its maximum, as the lamp operates, various processes (plasma, chemical and thermal) within the lamp cause a gradual reduction of lumen output. The degree to which the actual light decreases with operating time is referred to as the lumen maintenance.

9. What type of gas is used inside the lamp?

A mixture of inert gases such as Argon.

10. Does the operating position affect the Lumen output?

No. The universal operating position does not affect the performance of the induction lamp system. The reflector of the fixture is used to direct the light to a designated area.

11. Is the induction light dimmable?

Yes. In theory the induction lamp system is able to dim to 30% of the normal lumen output. However, we would not recommend dimming as this would severely reduce the life of the ballast.

12. Is the induction lamp vibration resistant?

Yes. As induction lamps do not have electrodes, they are more reliable in high vibration applications. The induction lamp has proven durability in all external applications.

13. Do voltage supply fluctuations effect the performance of the Induction system?

The IC (Integrated Circuit Board) in the ballast guarantees stable current under voltage fluctuations from 170V – 250V. There is no noticeable affect in the light performance (Colour Temperature CRI) as a result of voltage fluctuations.

14. How can induction lights be disposed of at the end of their life span?

Light: Although a very small amount of Mercury is used, it is recommended to treat the lamp as small chemical waste. The lamp can be recycled together with other low-pressure discharge lamps. Follow local authority regulations for disposal of this type of light source.

Ballast: This component is a RoHS compliant device, which can be disposed of with normal care. It is recommended to dispose of the ballast as normal electronic waste according to local authority regulations.

15. At the end of life must all of the components be replaced?

Although all components are separately replaceable, induction lamps are almost always supplied as a system, even for re- lamping. End of life usually means the ballast must be replaced, and at that time it is usually recommended to replace the lamp as phosphor degeneration at 100,000 hours lowers lumen output to 35% - 40%.

16. Why is induction technology worth more?

Induction lighting systems offer five to ten times the life of HID systems for only two to three times the cost of the HID lamp and ballast.
