My thought's on induction lighting

WTF. Does inda-GRO use magic LED's? With special spectrums no one knows about except them? $1500 for for a 400w with 40w's of leds. Am I missing something?

quality and longevity... the most expensive parts are the boards, the housing and the 730 leds. IR 730nm leds are super expensive every where. I f you can find them. the 730's run off a lithium battery with a 5 min charge at lights out..

look at every other induction company. they all; are either $100 less or $400 more for lower quality

the inda gro induction has a 10 year warranty and the led pontoons have a 5 year warranty. What other company has that.. no changing bulbs for 10 years. no spectral degrading for 7 years.

460 watts for 4x4 is awesome. You're stuck at putting a value on each watt and watts are irrelevant to plant growth. It's about par, cri and efficiency. in the long run The inda gro combo is far cheaper than running hid. the cost orf replacing and disposing of hid bulbs every year. almost quadruple the electric cost with higher watts and more cooling and another fan to vent the lights.

My buddy runs 10 1000w's i figured 15 inda gro's could replace the 1000's. $22,500 upfront. at full price. for sure there would be a bulk discount . In one year they would save $7,000 on electricity and $2000 on bulbs (replacing every 6 months). so in 2 years the savings pays for the light.. on top of the better quality , frostier and denser buds they will be getting.

There are bulk discounts on quantities. I visited them last week and was surprised to see how much their 4 pack business has picked up. These 4 packs are more geared towards the commercial grower in that it allows eight 4 pack boxes with 32 individual lights per pallet. This cuts down on the cost of freight, packaging and handling substantially and if you're in this realm you're certainly not paying MSRP.

Hmm 'WTF'....Yes you are missing, for whatever reason, information that can easily be found on the IG website. The Pontoon diodes are clearly stated as 660nm for lights on and 730nm for lights out. The 730nm diodes run off an op/amp circuit which IG designed that powers them off of li-ion batteries. 'WTF' you're a degreed EE. If you don't like the concept, design, or what they charge, build your own and see 'WTF' it entails and costs. As to the lamps, why not compare the spectral distribution graphs and the individual phosphors being used in a China direct against an IG. This information is also found on the IG site and within the posted MSDS sheets. If you can kindly reciprocate by providing me with an MSDS of a China 'WTF' direct I'll send you a blunt of my finest. And if you care to do a public side by side on RIU with any other induction grow light made on this (or any other) planet, where you show it outperforms the IG I'll make it a zip of my current 'WTF' top shelf; Cherry Pie.

Happy gardening!

High price compared to what? A CFL? I've been growing for 30 years and if you can show me a single CFL grow that consumes 420 watts, 460 with the Pontoon, and yields in the 1 gram/watt range I will bow to your superior intellect and skills. Until then I remain satisfied that my investment has an ROI of 1/2 a crop cycle. BTW that's a 4 year old video. Ed has a formed a different opinion since that video was shot and as 'expensive fads' go, he runs the 420/Pontoon combo's in his own gardens.

I have nothing against LEDs. I use them as supplemental lighting they work well with T5s or PL-L 55 fluorescents and reciently a company has come out with a tri phosphor led that come close to matching natural sunlight http://trir-pj.com/en/technology/ with a CRI of 97. so leds are coming of age.but as a DIYer I build my own lights and grow MMJ for non commercial use so pay all cost out of my own pocket.people claim to get 1 gram per watt with every kind of lighting but when you grow for personal use and not for resale cost and quality are important considerations everyone has their own favorite lighting system and this debate will never be settled. but I would need to see a well controlled comparison grow involving a variety of strains that demonstrate a clear advantage that justifies the higher cost. the companies that make these expensive grow lights can't even agree on the best spectral balance to use. there are cfls grows on youtube that claim 1 gram/watt and the induction lights that I have looked at have a lower lumen /watt output than T5s or PL-L lights.like led grow light makes they try to confuse the issue by using a rating system that has no baring on growing plants.low intensity pupil response means nothing since I do not use low intensity lights to grow my plants. I give them as much light as I can in my grow space. induction lights will be replaced by leds or plasma lights in the near future. both technologies are much more efficient and the price will come down in time.even 5630 led strip lights are more efficient than induction lights and do a great job of covering the 550-700 nm portion of the spectrum. 660nm led don't hit the chlorophyll A S1 peak and large amounts of deep red are not needed if you have enough violet to drive an S2 peak in chlorophyll A.warm whites work well for flowering without the less efficient monochromatic led pontoons
