tbh i don't really have a good grasp on what inductive lighting IS.... my only undertstanding of the word 'inductive' is in the context of 'inductive heat/elements' (and i don't really get how that works either....)..
docrock do you mind shedding some light? (

Inductive lighting is the new kid on the block. We're just going to try em out and see what happens. I'm hoping the small lights can be offset by using very small plants in a small area. I have seen inductive lighting available in up to 600 watts, which they claim is the same as 1800 watts of HID. I for one, would welcome any REAL option to lower my lighting and cooling costs. We know that HPS uses brute force to get the job done. Don't get me wrong, you see what's in my grow...until I see different HID is what I use. But, I'm going to keep an open mind always. Besides, tests are fun, and put to rest all of the speculation.

for a large area Id go with white pant, panda film would be a costly investment.

...thank you wiki!!
i'm very excited for you guys!! (and for the tests, yay!) electrodeless is the wave of the future.
docrock, what is the heat footprint like on these guys?

wow very interested in this lighting, havnt read all or anything on this lighting? but a 600 being equal to 1800 watts of HID!! and less heat?

A Philips QL induction lighting system, where A) Discharge vessel, B) Tube with power coupler and C) Electronic ballast.
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 transferred through the glass envelope solely by electromagnetic 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 the amalgam (a solid form of mercury). The excited mercury atoms emit UV light and, just as in a fluorescent 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 antenna called a power coupler, which consists of a coil wound 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 high frequency. The exact frequency varies with lamp design, but popular examples include 13.6 MHz, 2.65 MHz and 250 kHz. A special resonant circuit 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 of transformer, with the power coupler (inductor) forming the primary coil and the gas discharge arc 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 of for use with renewable energy (solar & wind) powered systems.
In other conventional gas discharge lamps, the electrodes 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.
[edit] Advantages
- Long lifespan due to the lack of electrodes - between 65,000 and 100,000 hours depending on the lamp model;
- Very high energy conversion efficiency of between 62 and 90 Lumens/Watt [higher wattage 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 conventional 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.[12]

Looks like Docrock is our new local induction lighting guy. I'm almost afraid to ask about pricing. Docrock, what is the current state of production on these bad boys? Are the commercial use units the same as the growing units...meaning can us growers expect a price drop as they become more popular in the commercial circles? Do you have any spectrum info? You may as well post the prices. We gotta know sooner or later. I'd also be curious to know what the markup is on these things wholesale vs retail. I have alot of experience with Marine Electronics (radar, plotters, etc...), and there is very little markup on these items...like 15%. I keep hoping when I see these huge prices on Plasma lighting and the like that there is a 100% markup, and I could expect big savings by purchasing 15 lights or so. Any info on that front?
Sitck around Doc...I have a feeling that this little group of Grow Junkies is going to be grilling you pretty good. LOL
Kitty, how do we Baverb these lights? Tape em together back to back?

No worries, Endless. It's about the learning for all of us.
I'm just happy that we have 500+ replies and only 1 really negative response (California Tsunami guy), and one borderline neg response (another Cali comment). If you look through the threads with this many people involved, you'll see that this group has done great. I'd be thrilled to
burn with every one of you fuckers! That's it...group hit...I'm heating up the Vap.

There really is nothing to complain about in this thread haha. One of my favorites on here. A large scale op with pics and a grower willing to share/answer questions. And a grower who no question knows what the hell he's talking about. Only ones negative around these parts are trolls/attention whores. Sermon over lol

they look like they'd baverb just fine on their own (at least the diagram at wiki does....); there's a ballast involved...? i don't know how well i would handle baverbing the fluoro-style induction bulb though -- i can't deal with vert fluoros, give me a headache in 2.2 minutes. although, when you take out conventional fluoro issues like flicker and refresh rate (which induction seems to) this may be less of a problem for me. which makes it EVEN MORE exciting. omg.
i'm kind of a grass-whore. will trade sexual favours for primo. does it still count if i only have the one client and he's kind of legally bound?

I have to get used to Baverb even with 600 HID's. We hung 2 for a couple days while I was waiting for reflectors. I'm not used to having those lights at eye level blasting out my retnas. 20 years dealing with hoods, I wasn't ready for the vert bare bulb. My eyes were cooked for the whole night. I have no idea how you guys work in the room with all of those lights shining in your face. I need me some welding goggles.
The whore thing only counts if hubby leaves the buds on the nightstand for you in the morning.

Are you wearing Polarized sun glasses? Polarized blocks out 50% of the light, rather than just being a dark lens.
