Xlg-240-l-a, 6.20 weird voltage 342v max 93% efficient and 700ma max current but you can make it work with a long ass series circuit, would be perfect for my xpg3 boards. 8, 48v boards in series would be very close, think I'll buy 2 definitely worth the money.

Thats ridiculously cheap. Though you would be working with fairly high voltage; make sure your soldering is good if youre going to do a +100 led string. The nice thing in a setup like this is that you would be able mix and match, add as many uvs/reds/far reds as you like cause everything is at the same string in series.

15 h influx series strips would be 22.8v per strip at 700 ma, would be 16 watts each 240 watts adds up on paper and datasheet probably get just under 240 tho

This thread makes me wish I knew how to solder. Would be cool to be able to source single diodes and starboards to create some supplemental strings. Lots of cool stuff to be done, just no skills. Hopefully I can take the time to look into things and try to figure out a simple/safe technique to try.

Keep up the cool work though. Look forward to more of your projects down the road.

To solder a mono diode is something you learn in 2 or 3 tries. And to solder leds to pcbs is not that much harder; i know people who just tried and did it. There are several diy ways; even with a frying pan, hairdrier or panini oven.

Id defo recommend trying to solder together a mono string to go beside your standard light. If you use 4 up diodes your doing a quarter of the soldering of what monos would normally take.

If you look up on YouTube how to reflow solder smd led there are few videos. A clothing iron set to cotton works very well with the solder paste I use. Just need a little practice and patience and you will get good enough where you don't gotta worry about scrapping boards. A lot of companies sell solder stencils which makes it a lot easier, these I bought are a bitch cuz the diodes are so close. I made a royal blue board and 2 more 3500k 90 CRI boards today. 6 down 12 to go all I have left are white diodes and maybe some photo reds

Could you give a bit of info on those pcbs? Like what diodes do they take in what combo and price and aource? They look really nice. I quite like the 4up options

I bought the 16 diode boards from
adurasolutions.com

highly recommend them but there's min orders it was 120 for 28 I think like 2 years ago, it been a while. Those 4 up copper ones I use are my favorite. They come from

20mm MTN Quad XP / 219 DTP Copper MCPCB

The 4 up have been sold out forever they must have just restocked they will not last long. I'm sure if you talk to someone you could get an even better deal


They can be made either parallel or series, with these little bridge things come with em. Any 3535 with isolated thermal pad will fit, nichia 219c or 319at, Z5M, xpg,xhp35,lh351 there are hundreds it's like a standard size.

The flashlight companies are on another level with led tech, they been doin this since led came out, grow light companies can learn from them. just my opinion

So.. I sent out for a quote on the MCPCB from new energy looking to get a price and min order. I would like to build some of these, I d almost rather it had 5 3030 osram SSL pads for the reds because xpg3 photo red is to expensive around 3.50 each for top bin, you can get the osram hyper reds way cheaper with the same 4.6 ppf/w. I do believe the cree diode is better overall tho imo, so no big deal

The MCPCB from the cree reference design is a no go. Oh but they'll build em and sell them to me, I asked for pricing on 100 - 200 boards, and a solder stencil. If they can sell the board assembled they could legally sell them bare. Mcpcb is one cost that you can't get around. It's no easy feat to diy one that is worth using.
