hes right if ya do have one around check it out pick up 32' of half inch thick l angle for under 20$ ( which is a little harder to work but it adds thermal mass to help cool things down )

Is there holes in the heatsinks in case I just want to hang them up individually ? btw, thanks for putting those kits together, in the end I think its comes out at roughly the same price per watt as the diy 200watts bars I built a while ago, except this is pretty much ready to fire up.

Hi @GreenSanta

Thanks for the feedback - this is an exciting product and we are glad to bring good quality lighting to the market at a fair price.

We do include (4) drilled and threaded mounting holes on each heatsink - they are located near the edge of the face of the heatsink (10mm inset on center of hole from outer edge) and are located at the 12, 3, 6 and 9 o'clock locations.

We include cap head hardware that can be used to attach to L-channel frames as well as anchor points for individual suspension....or a variety of hanging options. You could attach it to a swivel apparatus and point it pretty much anywhere you desired. Lots of cool options. We include enough wire between each COB that you can really get creative.

Regards,
Dan

I can't decide what to get for my 3 x 3. I just received a 2ft AgroMax Pure UV bulb and fixture I plan to hang dead center. Here's what I'm contemplating:

- 1ea 5 light kit - X pattern w/ one centered

- 1ea 6 light kit - H pattern with two lights slightly off center in the H center

- 2ea 4 light kits - one kit per straight bar

What do y'all think?

- 1ea 5 light kit - X pattern w/ one centered (>>hotspot in centre<<)

- 1ea 6 light kit - H pattern with two lights slightly off center in the H center (>>awsum layout with nice even spread<<)

- 2ea 4 light kits - one kit per straight bar (>>more intense spread, 8 COBS should yield more <<)

The 300w 6 cob setup would give you a ppfd of 900+ also. Plenty of light. But you could do the 8 and dim down a bit for more efficiency, and have the option for more light. 8 in a pattern:

X..X..X
X..O..X

Good info thanks!

@RainDan I noticed on your 2 COB light with the stella lenses, it's labeled as a 200W light. That's absolutely not true. You're not running those chips at 100W ec. So why say that?
Also, why the hell have you not made a 4 COB light with Stella lenses? That's what I'd be after.

how can you say that for certain based on the light specs? what if he is using 72 volt chips and a meanwell driver @ 1400ma ?are you sure you dont wanna back off that silly ass post?

You mean the 2 cob light that pulls 210w? Probably 100w each. :D

I also noticed the photon ##s look off. Says 86 par watts. Times 4.65 QER is a ppf of 400. Ppfd of 713 for a 2'x3'.

noob question, so running a COB at 50w vs. 75-100w involves moving from a 1.4a to a higher amperage driver? and one can dial down a dimmable driver to increase efficiency, but there's less an efficiency gain with higher amperage driver vs. 1.4a, particularly with 3950? hope that makes sense.

Voltage times amps equals watts. So with the same voltage cob, higher amps means higher watts. There's also a 72v version of the 3590, and can be ran on the lower amp drivers for higher wattage each chip. (I have 2 x 72v 3590s on a hlg 185 1400, and dimmed to 75%(72v * 1.05A = 75w each chip).

Less efficiency at higher watts per chip, yes. To compare, the light mentioned and linked in my last post has 2 x 3590s at 100w each(210w at the wall) and gives a ppf of ~400. Where the 4 x 3590 200w kits(50w each)(probably ~210w at the wall) gives a ppf of 520.


Have to find that balance of efficiency and cost(no point in replacing a light if if costs more than you'd save in electricity/bulbs over many years)

Good question!!! Using the PPFD calculator i got 671 ppfd in the 2x3'.

On the COB optic thread where optics are tested aginst reflectors and bare bulb and the the stella HB DID have 101.83% higher metered umol readings than a bare cob(bare 1356) ....... and 42.48% higher than the best reflector (KB80 1935) so?!?!?! maybe the stella Hb(2757) is damn good at directing light. Maybe timber Dan used a PAR meter.......or guessed or miss typed or was in a tight tent or who knows. Im just pointing out how damn impressive the Stella HB is.....because it helps me justify owing 20 of them :)

this gets me thinking about the options. I'm an old school PC overclocker, info in your post helps put things in to perspective thanks

@Airwalker16
Why don't you stop posting bullshit in other peoples threads? You clearly did not take the time to research the information that you draw your conclusions from. Most of your posts are asinine, a lot of them have a condescending tone (which is ironic), and you often times have to be corrected for stating false information or drawing false conclusions.

Please Stop.

Hi @Airwalker16,

It looks like others have already addressed your question regarding the wattage at which we drive these models. It is not an exercise in efficiency - that is the DIY kit side of things. Our fixtures are kept well within the correct parameters of the heat sink dissipation when actively cooled and yes, they are 72V chips run @ 1400 mA (Meanwell HLG-185H).

Our pre-built fixtures are not for everyone. Some have Stella HB lenses which some people like and others do not care for. Different strokes for different folks. I love our line of pre-built lights - efficient they are not. They are powerful and the Stella lenses are watertight so there are some applications where this is important. I love our line of DIY kits because they are basically our pre-built lights without the case and cooling, which reduces cost and also gives growers ultimate flexibility in designing the lighting situation of their choice. And, if one wants to, they can mount Stellas on our kits, or whatever they choose to do. That's the beauty of it.

Our PAR #'s are all calculated using an Apogee meter. We have not tested our equipment in a sphere. All measurements were taken in a 4'x4' standard tent.

I appreciate your feedback regarding a (4) COB Stella version - we will take it into advisement on future product development. Due to the 72° angle of the Stella HB lenses, correct spacing between COBs is important, which is difficult to achieve in a case unless it is custom built to those size parameters.

Have a good day.

Regards,
Dan

72 volt chips then. I see.
