Cheapest idea that keeps running across my mind is building my own out of the V series strips. Nice copper pcbs but limited to 2835 diodes. Far red strip would be $5 in materials and Deep/photo like $7.50 but for the deep/far reds you have to order 1000 diodes, so enough to do 31 2ft strips. I may go this route for a few far red strips but the deep/far red diodes are to expensive to build just a few. Other option I was considering last night was mixing in some 2700k 90cri strip that are $1.50 after tariff and look to have plenty of red in the spectrum.
Is Kingbrite (through Alibaba) a viable option for you? They sell 560mm supplemental strips. They have 660nm or 730nm, and also strips with both wavelengths. They have 11 diodes wired in series. The Cree XP-E2 would likely be my choice.
Which 2700k strips?
Could you up some links to this? Ive also been looking into 2835 footprint
SI-B9W111560WW ... Not recommending this to anyone as I have not tried it just saying it could be a cheap option to mix in with the 4k H strips to make it more suitable for flower.
Not sure what the rules are for linking to other forums but if you google the part # for the purple sunplus 2835's you should be able to find it. L1SP-PRP0002800000Could you up some links to this? Ive also been looking into 2835 footprint
Ive had a a few good impressions of 27k90cri for white base.
I know the sunplus range, seems quite nice, what pcbs do you use? Im.looking for 2-3 channels pcbs that could be worked at home. And whats you smd solder technique? Ive seen people talking about friying pans, grill ovens hot air/hair dryers.
From what ive seen there are other alternatives than osram in the 3535 range that will work fine when you use them at twice the count/half the power. Also, uv is hard to find decent in 2835.
The sunplus 2835 would go on the V series strips.. No clue about custom PCB's. I'm going to give it a shot with 2 heat plates from one of those hair straighteners. If that doesnt work I'll prob break down and buy a little heat gun.
SI-B8U15156CWW is currently the cheapest 2 footer but could also do it with the 1ft strips if you want something smaller
I did the frying pan method with lower temp lead liquid solder. Worked like a charm
On star/smaller pcb right? Not a strip? What kind of led's were you working with if you dont mind me asking?
Nice, thank you! Still using them or have you moved on to something different?
Moved along since them. I replaced them with small cobs, then got a bigger space. The cycle continues
