Lighting Need some Help! 300 Watt old Modell (60x5 Watt Chip)

[MediScrogs]

Hi,i have been using the older 3x96 with the 3 fans and getting good bud but i bought the newer one with the 5x60 and one big fan and i noticed the light is a different colour,it looks more natural/blue than the old one,its also slightly smaller lengthwise so i could actualy fit 2 of them into my closet now.......what im wondering is if its better than the old one? Would the old be better for flowering since it looks more red?(at least to my eyes it does) Im also thinking it looks less bright..........like the old one used to mess my eyes up after looking in the closet but this newer one doesnt have that effect it feels much easier on the eye. Do you have any opinion of it yet?

I have an "old" style Mars 60 x 5w, and it does have more of a bluish tint to it. Overall, the light color seems to be more blended so it's closer to natural light (i.e. sunlight) rather than a loud mixture of red and blue light. Well, it is still more loud than natural but.... I haven't finished flowering under it so I don't have any opinion on it beyond that; it does work fine at the moment. I think visible brightness of a light does not tell the whole story of how much PAR energy it is actually producing.

The best led I have seen in person is not on the market yet. It used a series of 10w cobs, needed no cooling fans, weighed almost nothing (remote power supply) and produced a fantastic white light with a slight tinge of red to it, but was predominately natural light color and very pleasing to the eye. Less wattage needed due to spectral efficiency.

I'm sure the best is yet to come for leds.

Please tell us more.....very interesting

They are intellectual property of the designer and will go into production in Canada this year or next for large scale greenhouse application. I'm talking large scale. To begin, they will be used by the company for their own greenhouses. There is some interest in producing them for retail availability but they have a lot on their plate in terms of scaling up the projects they currently have in motion, and is not really vital to the mission of the company to produce the lights for retail.

As far as tech, they achieved good spectrum in a cost efficient way. Platform was an aluminum bar with fin extrusions for cooling, no fan was needed to dissipate heat. Warm to touch but not hot. Bars were like 2" wide, or maybe 2 1/4" at most, an inch and a half of height, and standard lengths would be 2', 4', and 8'. Scalable with option to the grower in terms of how close the bars would be--i.e. run the bars with 12" between them, 15", whatever you would want. 10 watt cobs placed at like 6" intervals along the bar or so. The aluminum really weighs almost nothing, like 1 pound for a 4' bar, you could hang it with plastic toy chain or thread if you wanted. No noise, no wasted watted on fans, no heavy housing needed--wiring goes to a remote power supply.

Nice white daylight with just a hint of deep red, they hit the deep red nicely, and IR. Less wattage needed/no spectral waste.

Here's a photo, Corgy:

Here's the spectrums for the two versions:

Not sure I can say much more than what I've showed you, but the way to do it is out there.

Thanks a lot.......no retail......seems that patience is the name of the game for us......tail'ers

Anyways, it looks similar to these........beam angle control, Digital Distribution, no fans, no secondary optics, no diffusers......what's not to like

and these here cheap bars that is severely tempting me for a dash of longitudinal side-lightning

yeah, looks similar, but the illumitex is 4-channel, I don't see any spectral analysis on it. I'd like to see what color the light is when it's on. Regardless, it shows what is possible as far as design that would be an improvement over big heavy box housings with multiple fans. Maybe more manufacturers will figure out how to do this and get them to market so we can get our green thumbs on them.

The bars on ebay look like they're just mixing two colors of led.

True, but I reckon they can't be much different from old Mars style and UFO.....and just for side light and a giggle.

Meanwhile, @pop22 made this Termilluminator grab my attention http://www.bmlhorticulture.com/spydr-600-grow-max-spectrum/ .........movable bars to reduce wasted radiation.........320w actual draw......maybe one day available in Europe too!

That looks awesome all but the price tag. Adjustable every way that's quite a brilliant idea

These dont' look good to me. First telltale was the concentration of wattage in such a short space--they're not putting out the right spectrum IMO, then look at the purple/blue-purple color of the light, it is nothing like the blended perfection of natural light, which is mostly "natural/clear/white" looking for lack of better description.

No way I would pay $1299 for 320w actual draw of that.

Just my 2 pence.

None of my current lights are as advanced as the design I referenced above. Designer is brilliant and worked for Phillips many years ago among other tasks they have completed and is an actual engineer not a toady in a garage workshop. The spectral charts are authentic for what that's worth , but I'm not invested in what people think about that at all. I'm not selling those lights to you, and neither are they so I'm not asking anyone to believe anything about them.

I'm not wanting to sound harsh or supercritical here. I think when I read my post it may come across that way. Sorry,

I know this thread was looking for input on how people like the new "old" 60x5 Mars.

I'm just saying that LED tech still has a lot of advances in application yet to come as scientists understand more about how plants respond to and use each spectra of light. Just look at the Holographic series killing it at 75 watts, there's definitely something good going on in their R & D rooms to configure that out, and get some diffusion technology going. Amen.
I know TaNg is blowing the doors off his house with those, hella yeahs !

If it were easy it'd be everywhere already, but there's few manufacturers that will actually show you the spectrum their lights produce and that's a solid fact.
