Limo's CXB3590 build

[Growmau5]

I have been using "surface area cm^2" as equalling the square centimeters for every inch of heatsink....

I was doing the same thing for a while. since in supras chart at the top of each profile it says : "in or cm - in"

every calculation I did, i was like " christ, thats a f*cking huge heatsink" lol

UOTE="Limosnero, post: 11883092, member: 26804"]What do you think of this driver & price? MW driver HLG-185H-C1400B: $58.5usd

I'm told I can drive 4 COBs[/QUOTE]
Bonjour
Where did you find it at this price?!?
And mixing metric and imperial system is always a bit confusing!
I know that, trust me on this one...I have to convert everything since I am on riu...inch foot galon oz!in, mm,cm,M, ml,cl,L, so when you are too stone it become a bit fuzzy (hazy!)
Have a great day ★

That price is through kingbrite. & yes I bet it's a challenge even when not stoned

 

[captainmorgan]

Have you made any design decisions yet?

Bonjour
Ok from jerry...but 40$ shipping...ouchhh!! It took only cob and holder and china post option 10$(2 weeks to wait from payment! )
Have a great day ★

Have you made any design decisions yet?

I've placed an order for...

>8 - CXB3590 3500K CD 36v
>8 - Ideal holder 50-2303CR
>2 - MW driver HLG-185H-C1400B

Still open to heatsink & design ideas.

 

[Growmau5]

congrats Limo, its pretty exciting once you're committed and the cash is spent & products are on the way. know u just have to build the thing.

For Heatsinks, u might want to check out Realstyles setup. (thread here, & YT) Same components, but he is scaled up for a larger space.

also, Werm11's configuration..

Another b3590 build. Cut it out. Let some stock build up so I can order some this winter. I guess my Veros will do until then...

 

[Limosnero]

I'll be ordering another 24 in about a month \m/

 

[Growmau5]

i ordered 32 yesterday, Jerry is probably running low...

 

[littlejacob]

Bonjour
Jerry is going to be rich...
And maybe thanks to all the buyers the prices are going to stay stable and the quality at top level!
Have a great day ★

40" of the 5.375 profile...gonna do a 3-2-3 on 3 heat sinks...eventually add another heatsink & more COBs for a 4-4-4-4 configuration.

Bonjour
Nice pics...!!!
Best eggs I ever seen!
Wish you are going to have a good time with your build

 

[Limosnero]

Thanks!

I'm going with 3 - 36" x 4.9" heat sinks. If my calculations are correct, I should have just under 200w of passive cooling per 36" length. Was going to pick up from HSusa but was about $20 shipped...I'll spend more on gas so shipping wins.

Found some sturdy angle aluminum lengths @ Home Depot & will tie all together using 2 pieces on opposite sides. Going to keep the 3x2x3 COB pattern for now & evaluate for any future design changes.

Does anyone have a suggestion on where to order connector kits (wires/plugs) for the Ideal holders 50-2303CR? Also, the drivers have a dimmer option...looks like I need to supply the dimmer...suggestions?

Sorry, y'all, hate to disappoint, but your method is incorrect. The numbers I listed are the correct #'s minus rounding off....just want to end the confusion

@CanadianONE can maybe verify this for me.... with their spiffy sheet!...

I come out to roughly 76 watts of passive cooling for 36" of 4.9" heatsink....and that is Supra's recommendation of 110.cm^2/watt for passive cooling....

76.856 watts to be exact @ 110cm but my spreadsheet is calculated at 120cm/2 (recommended by Supra last time we talked) @ 120cm its 70.451 watts.
@Abiqua maybe he is referring to active cooling 36" of 4.9 profile at 120cm/2 is good for 211.354 watts actively cooled.

 

[Abiqua]

@CanadianONE

read page one, after a moment of weakness and being incorrectly "corrected" and by two members I really enjoy no less, I just wanted to clarify to @Limosnero [It is not per cm^2/cm fyi]

-200 watts of cooling would be with ACTIVE cooling only... on 36" of 4.9, so maybe that was a typo, my bad if so.....eairlier, incorrect calculation were given for 200 watts of passive cooling, I want to make that CLEAR!

 

[Limosnero]

Hmmm....could someone please layout the correct formula? I was calculating that for passive cooling.

234.78 x 91.44 = 21468.2832/110 = 195.17
