Basically what I "tried" to draw should explain it. I figured while drawing that it'd be 10 million times easier to just cut a round hole in the sheet metal and screw the fan to it rathe than to the heatsink and cutting a square hole to fit over the fan.

Looks like a good plan.

So you think the cobs I'm planning on using will be good for both flower and veg? Would it be smarter to buy 4 5600s and 8 4000s and make one heatsink with just the 5600s to use for veg then add the other 2 when I flower?

 

[Airwalker16]

And since your building such elaborate lights, where can I get these pieces of sheet metal I want and have them bent and a hole cut?

 

[Rahz]

I would go with 3500K all around personally. If I wanted a veg spectrum I might mix 4000 and 3000. I don't know where you read that 3000 and 3500 were bad for flowering but I disagree.

As far as sheet metal you might have a distributor nearby but if not you can check with AC or roofing companies. If you want someone to bend and cut you would need to check around for metal working in your area.

 

[Airwalker16]

Why not 5600 or even 5k for veg

 

[Rahz]

It would be fine for a dedicated veg chamber but even then the only practical reason IMO is the slightly increased efficiency. Plants don't need more than 10-15% blue light. They veg fantastically under 3000K full spectrum LEDs.

 

[Airwalker16]

Ya my 4 cob go green has 4000k 3070s and it's vegging like crazy. But I bought a bunch of ge bright stik I'll be pulling the diffusers off and using to help flower until I can build this light. They're all 2700&3000

No I will wait for cxd now and for hlg-320-1400b to run 10 cxd 4250 mega horti spectrum 84% efficient to be in the 5gpw range....soon...lol!
CU

when are these supposed to come out ..

 

[Rahz]

The HLG-320H-C is slated for 1st quarter 2016 release according to Meanwell. The rest of it is a spoof. The 320 probably won't be readily available until sometime 2nd quarter.

had me like i was just waiting for a response on cxb's 3590 ..what is this cxd 4250 lol

I agree!... a lot of great guys around here who share many things!
Sorry for my joke attempt...!
But who know...lol...I guess after cxa...cxb there will be cxc and of course in 2/3 years cxd...bigger more efficient cheaper more good things less bad...it is always like that!

heya rahz,

Im looking at an at200 or one of your lights to use in a small 2x2 ,I realize you probably dont want to do any direct comparisons and thats cool,but im just kinda looking to get your take on the differences between these lights.This is spectrum data from the led tubes but they told me its the same.Other than the obvious cost ofc.

As you have a 2x2 space and $800 to spend I will suggest you consider 2 T2-1400s. At a total price of $660 you could achieve a near theoretical peak of 1400 PPFD in your 2x2 space. The veg switch would bump it down to 840 which would take your veg cycle through 4 weeks in 3 weeks... How's that for a sales pitch? Best of all it's true! 2 T2-1400s will max out your 2x2. There may be equals but there is no better lamp for that space.

Stocking the 1400 series is not a priority so I don't have any available ATM. I just powder coated 25 shrouds and I think at least one of them is drilled out to be a T2-1400. If I don't have the enclosures for your order I can build them within two weeks.

@Rahz
Hey man, what is the shortest length of 5.886" profile I can get away with for 3 cobs using 120-1400 for 52w each (156total) or possibly a 240-2100 for 76w(228total) for running them?

 

[Rahz]

You can figure out the surface area for an inch of heatsink and multiply it by 6.45 to get cm/inch. Divide by 40 (using fans) or 120 (passive) to see how many watts of heat per inch the sink will dissipate. A 50w 3590 puts off 22 watts of heat and at 76 watts, about 38 watts of heat.

Your design is a good. I'm thinking I don't like warm air blowing in my face, so I'd like my fan flipped over to suck the warm air out the top of your cool tube. Duct work might be in your future..

Hey Rahz,
Im a UK bod, just read thru the entire thread.
I wanna join the crowd and congratulate you, great stuff man!
*Looks like a fantastic product.
*Having the drive to turn a passion into a business.
I think you have developed a great product and joined the market at the right time.
I do mildy agree with some comment on your website about it could be more succinct (possibly adding specific pages for the wealth of information).
Agreed with the 1st impression thing mentioned-if you get the success that you deserve remember scale will shift your key audience from "early adopters" to a more "mass market" type buyer (albeit within a niche market).
When you do grow your business do consider getting your packaging bespoke as it maybe cheaper than you think-it can be a simple design, your time costs money!
I hopefully do come across as patronising, I think you have done fantastically! I have some experience in buying packaging etc
If you are interested in licensing your product out do pm me!
At last, a product that "does what it says on the tin"!
Well done
