Now, that looks interesting. Quite a pricey bit of equipment (the 600, anyway). I'd be interested in hearing more about this, if anyone's got first hand exp with it.

They certainly look interesting. I was unable to open the video. Alas, the printed info is lacking. It appears that the led bars can slide on the backbone (if true, that is very cool). What size bars do you get for $1000? An A51 190 covers 2 x 3 @ $575, so 2 would cover 2 x 6 or 4 x 3. Most likely get a discount for 2 in exchange for a thread

I initiated contact with them

I heard back already. LOL. Brain dead= mind controlled programming.

Obviously, they have never seen mj grows under the new white panels

Now that said, they will build you an all white spyder

I would want ~ 30% of the WW on a separate timer though, you know, to kick up bud fattening

Yes I will be documenting it, I have a current one going with strawberry cough and skywalker kush, I am going to use it once it gets here next week. All lights are custom built in Austin.

You get (6) 3' bars, they pivot and can be spread out, the reason they can be spread out is to eliminate the issues with the led foot prints

I'm not bashing any other led brands because I myself use a shitty blackstar (my first light), but there seems to be more research is going into the bml lights, the princeton review is available unlike other led companies that claim to have university backing but have no proof

Don't get me wrong, engineering-wise, it's a great design.

The ability to spread the bars is to cover the plants as they grow

I am not familiar with their choice of leds, which may well be up to the task

My only issue is they don't even know that current whites have supplanted the need for monochrome diodes

They have solid white as well. They are not building a SPYDR 600 in all white yet, but I talked to them about it and they are looking at coming out with one. There goal for their first product was to produce a high efficiency product. (mmol/J)

Aside from what BML is doing, the draw back to all white is they are not as efficient at producing photons as red/blue/white blends. There is no such thing as a white LED. They are actually blue LEDs with a yellow phosphor coating over the LED chip. The yellow phosphors are excited by the blue photons and produce yellow photons. When the yellow and blue mix, you get white light. This conversion process is not 100% efficient, so a white LED will only produce 80-85% of the photons that a red or blue LED will produce at the same radiometric power output. Sorry for the science lesson, I design optics for a living and know a little about LEDs.

Correct, problem is we will NEVER find the perfect light spectral distribution for all cannabis strains with monochromatic leds. So very high lumen per watt (250+) all "white" led/cobs/smds are the future IMO; AND it's easier to work/diagnose issues under it.

Perhaps, or perhaps there are beneficial effects of monochromatic LED's in for photomorphogenesis that we just don't know about yet and likely it's a combination of the two.

Accurate 411 as to white being a blend/amalgam. Evidenced by several current grows and my own finished grow, monochrome R/B are totally unnecessary, and unnecessarily complicate panel design

COBs/Multichips are beginning to replace the old tech. One chip/cob + driver (some now come with DOB = drivers on board) + fan + spyder/sunflower heat sink + reflector. Multichips come in multi-monochrome, but also as 3000K/5000K + 6000K...
