Wikipedia induction light.....
Aside from the method of coupling energy into the mercury vapour, these lamps are very similar to conventional fluorescent lamps. Mercury vapour in the discharge vessel is electrically excited to produce short-wave ultraviolet light, which then excites the phosphors to produce visible light. While still relatively unknown to the public, these lamps have been available since 1990. The first type introduced had the shape of an incandescent light bulb. Unlike an incandescent lamp or conventional fluorescent lamps, there is no electrical connection going inside the glass bulb; the energy is transferredthrough the glass envelope solely byelectromagnetic induction.
There are two main types of magnetic induction lamp: external inductor lamps and internal inductor lamps. The original, and still widely used form of induction lamps are the internal inductor types. A more recent development is the external inductor types which have a wider range of applications and which are available in round, rectangular and "olive" shaped form factors.
External inductor lamps are basically fluorescent lamps with electromagnets wrapped around a part of the tube. In the external inductor lamps, high frequency energy, from the electronic ballast, is sent through wires, which are wrapped in a coil around a ferrite inductor on the outside of the glass tube, creating a powerful electromagnet called an inductor. The induction coil (inductor) produces a very strong magnetic field which travels through the glass and excites the mercury atoms in the interior. The mercury atoms are provided by theamalgam (a solid form of mercury). The excited mercury atoms emit UV light and, just as in afluorescent tube, the UV light is down-converted to visible light by the phosphor coating on the inside of the tube. The glass walls of the lamp prevent the emission of the UV light as ordinary glass blocks UV radiation at the 253.7 nm and 185 nm range.
In the internal inductor form (see diagram), a glass tube (B) protrudes bulb-wards from the bottom of the discharge vessel (A), forming a re-entrant cavity. This tube contains an antennacalled a power coupler, which consists of a coilwound over a tubular ferrite core. The coil and ferrite forms the inductor which couples the energy into the lamp interior
The antenna coils receive electric power from the electronic ballast (C) that generates a highfrequency. The exact frequency varies with lamp design, but popular examples include 13.6 MHz, 2.65 MHz and 250 kHz. A special resonantcircuit in the ballast produces an initial high voltage on the coil to start a gas discharge; thereafter the voltage is reduced to normal running level.
The system can be seen as a type oftransformer, with the power coupler (inductor) forming the primary coil and the gas dischargearc in the bulb forming the one-turn secondary coil and the load of the transformer. The ballast is connected to mains electricity, and is generally designed to operate on voltages between 100 and 277 VAC at a frequency of 50 or 60 Hz. Many ballasts are available in low voltage models so can also be connected to DC voltage sources like batteries for emergency lighting purposes or for use with renewable energy (solar & wind) powered systems.
In other conventional gas discharge lamps, theelectrodes are the part with the shortest life, limiting the lamp lifespan severely. Since an induction lamp has no electrodes, it can have a very long service life. For induction lamp systems with a separate ballast, the service life can be as long as 100,000 hours, which is 11.4 years continuous operation. For induction lamps with integrated ballast, the lifespan is in the 15,000 to 50,000 hours range. Extremely high-quality electronic circuits are needed for the ballast to attain such a long service life. Such lamps are typically used in commercial or industrial applications. Typically operations and maintenance costs are significantly lower with induction lighting systems due to their industry average 100,000 hour life cycle and five to ten year warranty.
Advantages
Long lifespan due to the lack of electrodes – Strictly speaking almost indefinite on the lamp itself but between 25,000 and 100,000 hours depending on lamp model and quality of electronics used;
Very high energy conversion efficiency of between 62 and 90 Lumens/Watt [higher power lamps are more energy efficient];
High power factor due to the low loss of the high frequency electronic ballasts which are typically between 95% and 98% efficient;
Minimal Lumen depreciation (declining light output with age) compared to other lamp types as filament evaporation and depletion is absent;
"Instant-on" and hot re-strike, unlike most HID lamps used in commercial-industrial lighting applications (such as mercury-vapor lamp, sodium-vapor lamp and metal halide lamp);
Environmentally friendly as induction lamps use less energy, and use less mercury per hour of operation than conventional lighting due to their long lifespan. The mercury is in a solid form and can be easily recovered if the lamp is broken, or for recycling at end-of-life.[citation needed]
These benefits offer considerable cost savings of between 35% and 55% in energy and maintenance costs for induction lamps compared to other types of commercial and industrial lamps which they replace.
Disadvantages
Some models of internal inductor lamps that use high frequency ballasts can produce Radio frequency interference (RFI) which interferes with radio communications in the area. Newer, external inductor type lamps, use low frequency ballasts that usually have FCC (or other certification) thus they comply with RFI regulations.[citation needed]
External inductor lamps tend to be quite large, especially in higher wattage models, thus they are not always suitable for applications where a compact light source is required.
Some types of inductor lamps contain mercury, which is a hazard if carelessly released to the environment in large quantities.
Induction vs LED
While induction lamp technology has matured in the last few years, it is often overlooked or underutilized in lighting applications since none of the major manufacturers promote induction lamps in any significant way. LED lighting seems to get the most "buzz" in the market as LEDs are promoted as the best alternative to conventional lighting due to their longevity. Induction lamps have a lifespan of 80,000 to 100,000 hours (depending on type and model), which is essentially the same as LED lamp lifespan. The major difference between the technologies is in conversion efficiency (energy utilization) and costs. This is particulary significant where large area lumination is needed, for example, outdoor, warehouse, or gymansium settings.
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 82 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 16000 Lumens while an LED version would only produce 11,000 Lumens (about 31% less light) with the same energy input.
Since the most powerful single element LEDs available at this time are in the 20 ~ 25W range, to make a 200W fixture, an array of LED elements must be used. This adds to the expense of the fixture since the cost of these more powerful LEDs is presently quite high and they require custom heat-sinks for thermal management. Since induction lamps use well established and mature glass molding and coating technology with electronic ballasts (similar to fluorescent lamp technology), manufacturing costs are lower and yields higher than LEDs at this time. Typically an induction lamps fixture will cost 50% to 75% less than a similar output LED based fixture. This cost gap will be erased over time as LED production ramps up since sold-state devices are more amenable to cost reduction through mass manufacturing techniques.
Well, we all know that Light Emitting Diodes are not considered for general lighting purposes because of its limited brightness and poor color rendering, but this is compensated by its high reliability and high color temperature. It is still a common mistake that many people make thinking that higher color temperature, say 6000k, means higher brightness.
LED however, does have the same theoretical lifespan of 100,000 plus hours as induction light, given that the integrated chip does not fail before the diode. Many LED manufacturers neglect to fit a decent high temperature IC or integrate some kind of heat dissipation device and their LEDs fail after only 10,000 hours. Induction light on the other hand, offers the same stability and lifespan as LEDs but is available in much higher wattages and brightness so that it can truly replace incandescent and discharge lamps as the next revolutionary lighting source.

My 4 day old 4oow induction light from china died?
I was shitting, did I just waste 468$.
It had a 5 yr warrenty (the same as the us induction lights).
So I sent Mr tony Wu @ Riant lighting a email telling him it failed.
I'm happy to report...
He Replied back almost imeadiatly that he would send another one out ASAP.
An they would pay for returning the failed unit to the factory in china,they realy want to to test it.
I'm very satisfied again with Riant lighting of china, despite my initial terror.
Ill have a new one soon. Tony Wu of Riant is a NINJA!!
All buisness have complaints with products.
Its how they deal with them that separates the men from the boys.
Ethics is buisness is paramount.
I feel riant handled the situation so good Ill pay ship the old ballast back.

Ahhh, that sucks dude. That's awesome the customer service you received though. I've been checking this out because induction auto grows are something I was considering, couldn't find ANYTHING on them. You're a pioneer sir! I'm still learning towards LED, but I've been doing a ton of research on induction lately. You may be the one to change my mind. Gearbear on here has an induction light as well, but he's not sharing his pictures yet. Pretty sure it's a 400W Inda-Gro. When you say " 130' " were your temperatures, what measurement is that? You're saying the light runs cooler than CFLs though so that's interesting.. The shape of the bulb appears to provide better overall coverage than CFLs could provide anyways.. Let us know when the new one comes in!
The temperature messurements of the riant Inducion light was with my lil infrared thermometer after about an hour or two operation the first night. There may be hotter places on the bulb? Ill have to check it more.
The cfl was just in the lamp in the shed I use for smoking.
But it appears to me the cfl was hotter (but much smaller)

The history of the induction light is amazing!
I see lots of folks on the net credit Tesla for this light?
Tesla did not invent the induction any more than Edison invented light bulbs.
Here's what I learned.....
"1884 Johann Wilhelm Hittorf of munster germany discovers the electrodeless discharge lamp. Hittorf is also known for the discovery of the cathode-ray tube in 1869
1880s J. J. Thomson thoroughly studies the phenomena of the electrodeless discharge lamp after initial discovery by Johann Wilhelm Hittorf (1884). Thomson like Hittorf is an established physicist. Cambridge, England
1893 Nikola Tesla first demonstrates his electrodeless lamp at the 1893 World Columbian Exposition in Chicago. His lamp looked like a large lightbulb and had strange greenish phosphors. His lamp was powered by the electromagnetic field of a nearby large "Tesla Coil". Tesla brought the lamp into the public eye and further improved the lamp. The industrialist later sued academian J.J. Thomson in order to secure rights to try to make money from it. A practical consumer lamp was never developed.
1904 Peter Cooper Hewitt developed an induction lamp that used mercury vapor (like today's lamps). He already had expertise as the inventor of the first commercial mercury vapor lamps. He worked on induction lamps with a sphere shape and double sphere shape, with external induction coils wrapped around the sphere or "waist" of the double sphere. PC Hewitt also developed internal induction lamps. General Electric, New York, NY"
Even though Hewitt is credited for the modern mercury induction.
It's certiian Charles Proteus Stienmetz who also worked for GE helped considerably since he invented AC, induction dynamos, and the induction furnace. Cp Stienmetz mercury light patent directly discussed fluorine gas, phosphor coating and producing white light?
http://www.google.com/patents?id=9xpaAAAAEBAJ&printsec=abstract&zoom=4#v=onepage&q&f=true
Seems Stienmetz work is more important to development of electricity an light than tesla.
