General DIY LED thread

LEDs in series, one driver per string. Drivers all connect to the power supply individually. You've got it right.

Thanks. I’ll do some in depth reading re: new thoughts on spectrum, and come back.

Appreciate it!!

@Lingwendil something like this with a Kessil look alike in place of the bulb

Something like this maybe?



If we change the shape to be reminiscent of an LED star that would be rad :)

What’s wrong with the top mounted fan that are designed for them? Also, I test fit regular PC fans on my makerslim and they fit fine.

I like not chopping my fingers off (figuratively anyway :))

Lol, are your fingers made of snowflakes? Scars are cool! Seriously- but why are your fingers up above the heat sink anyway?

They were available, just not really advertised. I bought my last one in ?July? of 2017, after sitting on the idea for a long time.

I have no idea why they weren't advertised more, they would have been really popular, and the price is very fair- I paid $60 for mine (20") at the time on special, plus maybe $10 for the fan. I have a feeling they didn't sell well enough and are being discontinued.

What I really miss is the T-slot profiles heatsinkUSA used to do, they were really nice for large fanless setups.

I am running three of the 20s over my 125 and love it! A lot of space to do what I want. I just seen them a month ago.

This is what Jeff @ Steve's said about Mint on a 3up:

This I would be interested in!

Same, a star with two sunplus/C footprints with a violet would be rad.

If the price is in line with existing offerings I would be interested in a few to start, if it helps you reach the 20pc minimum.

Jeff is cool. I might get a few if it's a decent price.

Let me see what he can do and I will come back with the results. So what do you guys want,just a C x ES x ES or C x SP x SP ?

 

[dantimdad]

1 mint, 1 violet 420nm, 1 luxeon

1 mint, 1 violet 420nm, 1 luxeon

How many would you like ?

 

[Steven Garland]

What do you guys think of these layouts ? I will need to order 2 cool blues and 2 cyan's to fill in some spectral gaps:

Outside row L : 1x 430,3up 2x RB 1x WW,1X 410-420
Middle Row: 3x Violet,1x Mint,3up 2x RB 1x NW
Outside Row R:1x 410-420,1x 3up 2x RB 1x WW,1x 430.

6x Violets surrounding 4x RB,4X TB,2 NW,2X WW,1 Cyan.

Top Row:1x Violet,3up,Violet.
Middle Row:Violet,Mint,Violet.
Bottom Row:Violet 3up,Violet

L-R:Violet,3up,Violet,Violet,Mint,Violet,Violet,3up,Violet.

so looking at ideas for a diy refugeum light that also is somewhat ok to look at too. looking at the freshfocus Cobs. this time the marbled Meat, big peaks at 660 and 450 with a bit of green so you can still get a semblence of white light. thinking one of those on a heatsink hung over a 16x16 refugeum.

 

[Lingwendil]

Yeah, I was looking at those a while back. I get the feeling that they would have a similar look to the old school fluorescent "colormax" types. I was thinking they may be nice for a macro tank with a bit of other colors (regular blue maybe) thrown in for some adjustment potential, could be a nice way to farm chaeto (or similar) en masse.

 

[Lingwendil]

Well, I hooked up the pendants just temporary to get an idea, and they look pretty rad. Think super fancy version of a kessil or orphek cranked up to look like a 20k radium. Exactly what I was going for. Need a little more "warmth" but it's very, very close as is. Swapped a white for a neutral white, and then a lime. Lime looks best (No surprise) but the neutral also looked very nice- it would however need something like a cyan to offset the pinkish cast you get from all that red in it.

As always, pictures always look like Windex.




I'm thinking a 3up of violet, cool blue, and either amber or lime. Still undecided. Maybe amber on the 3up, and a mint to replace a white?

I was running 300mA on the k16, and 700mA on the whites/cool blue/lime. I'm thinking whites/lime(or mint) at 1A, cool blue/violet at 700mA, and maybe a 300mA for the amber? Should be nice and adjustable for look.

Currently running 1x sunplus white, 1x lime, 1x cool blue, 1x k16.
