Limo's CXB3590 build

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

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! )

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.

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...

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

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

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

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.

@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!

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
