you could just use 8 diodes and bridge 3 of the pads?, thats what im doing with my far red channel. (not because i wanted 24v just cause it would be too much far red, im gona only use 3 or 4 diodes).
Is it difficult to make your own strips?

I meant for the white channels. 48V makes it harder to connect in series and keep voltage low at the same time.

Hi Rocket, yes we have a 2ft gen 2 board now with XP foot print on the centre channel, so 12 pcs of UVA, XPG-3 Deep Red etc. So we offer this as a 1,2 or 3 channel board, so you can order as just a single centre channel mono, so we can offer 420,660, 850mix
Cheers
Mark

Yeah that’s what I’m doing I’ve been trying to do everything myself keep prices down. If I knew how to have preordered sales & would have enough revenue to actually put in production I already order enough leds already I’m just trying to get the reflow oven now & im set. I’m gonna have it as a conversion kit sell first where you can buy for boards replaced it with the HLg 550 where is mine that way you can use the same driver 54 V to save money as that’s $150 driver And the cheapest way to have spectrum control is each channel has its own driver connected to a timer like he would just a regular light so for timers let’s say just $10 each and your set or once I have It in production I’ll be the cheapest way and I have a spectrum meter where I could have the light set with able to geometer and I can post the spectrum it produces CCT temperature the CRI and even the luxe along with PP HD on here for people because I even plan to do it myself There’s a bunch of the spectrum graphs with the channels at that say blue 50% red 80% white 60% see how much lux it is and the spectrum it will produce because I want this to be not just for cannabis butter lettuce as well people that Grow vertically lettuce or you know micro greens the light can be closer to the vegetables and with eight of the boards without a heat sink Cuz it won’t need 1 & 480 HLG driver more square feet can be lit and I’m also having a bunch of research that I’ll be posting from universities as lettuce with the 730 NM light and the white LEDs produces more Darren harvest as in weight

This video makes it seem involved but not impossible.Thanks. It sounds like it might be a little bit more involved of a project than I can dive into at this point.

Did something similar seven years ago ...

It can be done ,but I’m not sure if it’s worth the time ,money and effort .
Moreover one has to have the necessary skills to :
- Design a SMD circuit .
- Etch metal core pcb.
- Apply solder paste with stencil.
- Carefully align and place the devices in their solder pads.
- Reflow solder the devices ,following
the manufacturers solder scheme.
And quite few more ,actually ...
Only for the brave,I should add ...

It’s coming along pretty good but I got to say it’s not for sale because I got flagged for advertising which I got a pay for but other than that I got to say it’s just a project of mine To avoid my posts from getting deleted but thanks man yeah the board looks a little rugged in the picture but I should have a reflow oven coming in pretty soon and this is the first one I made anyway so I’m gonna have some hiccups you know but either than thatThe spectrum it goes office is pretty good. Lately I’ve been seeing what kind of Kalvin it can make.

Nice early attempt. Lot of residue, and alignment issues. But its early days. What paste and soldering method did you use?
T3 solder past and I used my stove top and put the bord in a baking pan until my reflow oven arrives. Like I said I’ve been trying to do everything myself to cut cost and make it as cheap as possible.
I’m using a Lighting passport spectro meter that uses Bluetooth to connect on my phone with the app how come you say it doesn’t look right. Here’s one of the sun I took

Will be better when your oven arrives. Then you can try match your paste manufacturers cycle, closer than using stove top. Very exciting stuff.
Thanks man you’re one of the few that actually hasn’t criticized or thought I wasn’t bullshitting about actually doing this.

just the peaks on the graph, where is the 400nm pump coming from?, then the 3 little peaks from 550nm to 620nm where are they coming from?. no k samsung white 301b has them? and they are obviously not from the monos?.
The 400 is from the 380uvb idk y it’s closer to 400 then 380
