While your garden looks nice, I still want to see a (or do one of my own) live grow with these lights before shelling out $700+ per 400 watt fixture. I need to see live proof, I'm a skeptic.
Same here. I just spoke to a rep at Inda-Gro since I found out they are based out of San Diego. I got some pretty good information and even a local hydro shop that has one currently set up and running (Pro 400 series) which I plan to stop by and take a look at this week.
I was looking into supplemental lighting for my 600w hps but now I'm considering replacing it with dual Pro 400's instead, but there is not enough information on them to pull the trigger

Saw these at a hydro show this past weekend. You can literally hold your palm on the glass a mere inch or two from the lamp and it is cool. The version (I think 700w) that was to replace a 1000W MH lamp was going for about $800 all inclusive (maybe a show special I didn't ask).
I'm in the market for another lamp, if this wasn't 2x more expensive I'd be all over it. I have been trying to rationalize a reason I need this tech, but my pocket book has won that discussion the past few days anyway.

I'm going through the same thing. My bill jumped $200 a month when I flipped the switch on my 600w hps, they save you up to 60% a month on electricity, that's at least $100 a month savings if I use 50% BUT the consultant on the phone said that in order to have similar results as my 600w hps in a 4' x 4' grow space (with supplemental) I would probably need to run 2 Pro 400 series or I will still need supplemental lighting, which is what I'm trying to do when I upgrade my space.

Hey guys,
I am not a grower but I am an Induction Lighting guy and Induction has received a lot of attention in your community. Energy consumption is about half of HPS while delivering the same lumen output. The pricing you received sounds like retail, it is not that expensive. Reach out to me to get some pricing and pictures of fixtures for your use. [email protected].
Thanks

QUOTE=chazbolin;4785005]Lighting is about 80% of my business as I'm an electrical contractor in CA. I was first introduced to induction and LED as retrofit for HID in parking lot applications. So I've had some experience with several different manufacturers and the distributors who rep them. Suffice it to say the LED's fell out of our general area lighting favor when we had 60% mortality within 5 months of a fairly large project and we could not get warranty coverage from the mfg or the distributor. They offered us Cost + 10% on an induction replacement which is what we eventually went with. No more LED retrofits for us.
I have also been growing for about 20 years and was hopeful that the LED's would be an low energy option but here to then LED was less then adequate. I want to share the induction because it is not widely known amongst our community. 200 & 400 series grow pics all under induction. When done right they are a game changer.

After I spoke to a representative at Inda Gro I was told that I might still need to add supplemental lighting to a Pro 400 in a DR120 (4' x 4') to get the same result as a 600w HPS.
For those of you already using one, do you think he is right or will a Pro Series 400 replace a 600w hps straight up?
I'm currently growing in a DR120W using 600w hps and am planning to upgrade to a DR120 in a few weeks and was researching supplemental lighting when a friend sent me the Inda Gro link. Now I'm considering making the switch altogether but the up front cost and no real information on them make's it hard to switch, especially for a n00b like myself.

If it sounds too good to be true it usually is 
In Holland you do a good grow (a great grow for some strains) if you yield a gram per watt light applied. So a 600W lamp grow should ideally yield about 600 gram (about 21 oz). This is under HPS. I have seen growers get that sort of result under cfl as well, but with much more difficulty. One of course is reflection. It's impossible to build an efficient reflector for the shape of these round tubular lamps. I have never, with any light, seen claims substantiated that with 30-50% less electricity use they could have the same yield. Even with LED you need about the same wattage as HPS to get comparable results. Now LED is very effective too, so effectivity of the light source doesn't say much. Moreover I see a lot of claims based on lumens or footcandle output. That is incorrect: lumens are for humans (I borrowed that one, thanks Roy!)
The standard measurements of light output have traditionally been done through the foot-candle, lumens and lux. They quantify how humans experience the intensity of light, based on the limited sensitivity of the human eye in the yellow/green area of the spectrum (around 550 nm). Plants however use a much wider spectrum for photosynthesis, called the PAR spectrum (Photo-synthetically Active Radiation), ranging from 400-700 nm
Human eye sensitivity versus plant sensitivity
Photosynthesis is not driven by brightness of the light according to the human eye or the energy of a photon (which varies for different colors) but purely by the number of photons in the PAR spectrum. You need about eight photons to bind one CO2 molecule. So to quantify potential photosynthesis it is all about the number of photons within the PAR spectrum hitting the plant. This is expressed as Photosynthetic Photon Flux (PPF – total photons emitted from a light source per second) and Photosynthetic Photon Flux Density (PPFD – the number of photons hitting one square meter of surface per second) and it is measured in moles or micromoles (µmol) of photons. You can measure the number of photons hitting your plant (PPFD) using a quantum meter, predicting the potential photosynthetic capacity of your light.
Now I did not write this specifically for this post I must admit, I had written it befor but I thought it would be appropriate to add.
Another important factor of course is spectrum. HPS does not have a really good spectrum compared to Sunlight, but fortunately cannabis loves red light. Of course you need more than just red light for a plant to flourish. But just to give you an example (which I can do because I work at a horticultural light manufacturer in Holland):
We measured two 1000 Watt lamps in our calibrated Ulbricht Sphere. One had a luminous flux 150,000 lumen, the other had "just" 135,000 lumen. When we measure with the quantum sensor though the second one has a higher quantum (micromole) output than the 150,000! So lumens and luxes do not say a lot really, it's a free burning measurement from the factory. Now let's just assume that you grow like many and cool down the lamp too much ar have a glass plate between the lamp and the crop and you don't replace your reflectors every once in a while. These three factors alone can cost you up to 15% of your valuable light. A dirty reflector alone can cost you 5% light in one year.
Anyways, that was not the point. I just wanted to "shed some light" over lumens, luxes and micromoles. Also it would really surprise me that under a 400 watt lamp you can grow 1,5 times as good as under a 600W HPS. Thats what you are looking at when you want the same performance: 600W - 1 gram per watt, 600 grams, 400W Induction, 1,5 grams per watt, 600 grams yield? I have to see it before I believe that. If you yield 400 grams under 400W induction you have my respect. And I'm always open to be proven wrong!
I think there is a place for induction lighting for small cabinets, but not for large scale grows. The growers that used to experiment or grow under induction that I know have since all moved to HPS and MH for veg, sometimes in a combination.

if anyones still looking at these quit falling for the local us reseller money making schemes.... get it direct from the chinese source @
http://www.aliexpress.com/store/401...less-induction-lamp-factory-direct-sales.html
furthermore... no dont go buying those damn so called "dual spectrum" lights. its just 2 color bulbs in 1 fixture. order in 2700k/6500k and youll get the same damn thing and save $$$$$$$$$$.
i never thought id post on here... but had to once i saw the load of bull that people go through to obtain a simple lamp

i use the dr120 and just put in 2-400's from inda-gro. just finished about 3.5 weeks of veg and my first week of bloom so far so good.
can someone point me in the right direction for a group buy? Im looking to try a few out.
I actually live right near the Inda-Gro location in San Diego, do they offer any discounts? Perhaps a savings on shipping too?
I of course will be sharing photos and experience for prospective buyers

talk with them over the phone and agree to a price then drive down there and snag them save on shipping. local sale (intra-state) means 8.75% tax as I'm sure you're aware. the place is a little hard to find as there's no signs. i talked them down a little bit on price bringing up being on disability and my recent bout with cancer. even at their full marked price though it's still a steal compared to HID when you consider bulb replacements, less wattage with the same lumens, less energy, less fans, no duct work, and you don't run an AC to keep it comfortable.

i would love to see something like that, please document it and take lots of photos, start a thread and share it here if you like
I just started my grow with those lights. Come check it out if you want. The link is in my sig.
How did things turn out for you ?
