a bit of bad news is Philips is discontinuing the retro cmh 400 watt and 250 watt versions and those bulbs kick as and are part of why i designed the chambers as I have...a replacement hunt is underway

Honestly, got zero experience with induction lighting for cannabis growing.. Been reading up on it since a friend of mine brought it up, but asides from that, can't really say anything at this point.. Don't really like dispensing advice about this tech I got no experience with ;-)

So far this is what I know about it:
An electrodeless lamp or induction light is a light source in which the power required to generate light is transferred from outside the lamp envelope to inside via electromagnetic fields, in contrast with a typical electrical lamp that uses electrical connections through the lamp envelope to transfer power. There are three advantages of eliminating electrodes..

Wiki also list a (advantage) & (disadvantage) critique: http://en.wikipedia.org/wiki/Electrodeless_lamp

But like I said, never grew with induction, seems like a cool tech to use for horticulture.. I'm also a big fan of Tesla~
You should stick with your "spidey" sense, grow/hydro ppl will always be "pro" for the products they are selling (which makes sense).. But I don't like it when they always use the old (Photosynthetically available radiation--PAR) sales pitch when (Photosynthetically usable radiation--PUR) is much more important :) Its all about the grow light's available radiant energy (of such wavelengths) that can be absorbed by the plant pigments-- which makes more sense to my wallet~

I can see uses for induction but do not see them being to compete with hid unless in a very different growing environment. It is afterall just a high powered electrodeless fluorescent and all the limitations of fluorescent are still present including lack of penetration. I am of the hypothesis that nearest to "Sunlight" possible is the ultimate goal where it comes to lighting. Hence I supplement cmh with t5 ho actinics and pinks and high uvb emission lamps as well. Also why I am pondering implementing kessil blues and reds as well.

I would like to know how induction does with veggin' primarily, yea.. light penetration would be the same factor as in CFLs (I see good results when ppl Scrog/LST while running CFLs) ~ Mimicking the sun's full spectrum would definitely be beneficial to an indoor grower :mrgreen:

I use kessils mainly as "supplemental nms" in-combination with HPS lighting, adding/enhancing blues/reds.. :joint:

is that a fact jack


i have been useing the eye hortilux- hps- and the philips - cmh for a couple of years now in this a double hood





and i hang my uvb off the side of it got lots of spectrums going on
i use a 400 hps and a 250 cmh i think uvb helps when useing lower wattage
wit 1ooow i doubt would need a uvb not enough in lower wattages

good karma to all

they have done so for good reasons. i have said it elsewhere and the reasoning is out there, but regular MH is far superior to CMH and comparable to HPS easily due to its PAR values.

anyways most T15 pulse strike MH bulbs are going to be on par with the hortilux blue or CMH.

No they have done so as they now have a complete 315 watt system for horti and this is their way to insure the recoup cost and produce profits. Gonna have to buy the system rather than the bulb. This was directly from a Philips Rep.

The cmh has a longer life, maintains output at a higher % and is much more spectrum stable than mh with the added benefit of the ceramics blocking alot of the IR heat compared to both mh and hps. Not to mention that they produce red and far red to a much higher degree than either as well as good blue.
I just ordered enough bulbs to carry me for 5 years so that by then the 315/860 systems will be affordable by then or something even better.

As you can see the par and spectrum are inferior....no hps nor mh even come close in spectrum nor spectrum much less stability

Where do you get this superior mh info from please?

Not enough uvb produced by any hid bulb to matter regardless the wattage... I use 2 horiz cmh on movers in PL Lighting Deeps and one veert cmh in a cool tube with Arcadia 12 uvb 46" T5's in the corners and mv zoo uvb lamps overhead

I want to contribute to this MH/CMH topic but I've been out-the-loop since early 2012, and haven't kept up-to-date with all the recent horticulture lighting tech that has hit the market..

So far just been working on different outdoor/greenhouse/aquaponic setups over here in Asia~

**although some .pdfs online will show that certain CMHs would have a wider range of available (nms) in its spectrum vs your typical MH.. thats the only useful thing I can add in-regards to the MH/CMH topic~

Thnx bruh, it was built from scratch by the previous crew from last season :P Gonna add swamp coolers and vents into the greenhouse, this dry heat is cray~
