Who makes/sells a reasonably priced red led strip?

[UpstateRecGrower]

Thinking about building a bloom light with all these 4000k Samsung strips I have, wanna add some red for flower, doesn’t seem like there’s many options? It’s for a big space so I’d like to find a reasonably priced option, if I only needed a couple strips I wouldn’t care..

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.

I'm not sure how much shipping would cost you, but this may be worth looking into as a decently priced option. You can buy just the strips or strips with drivers. You may want to look into getting the drivers stateside. In case you ever need to RMA them, it'll be less of a hassle with a more local supplier.

Which 2700k strips?

Could 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.

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-PRP0002800000

He did it with the 2.5% purple since it was the cheapest way to add red. The deep red diodes are like 50 cents a pop and make that option a waste of money since you need 32, but the far red diodes can be found for 17 cents a piece with a little searching and are a viable option in my opinion.

How a $7.50 v strip with 32 far reds would compare to $7.50 worth of cree or Osram 3535's on star pcbs is what will prob help me make my final choice on far reds to try. Obviously a lot less soldering but this is a hobby so not a deal breaker

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.

I keep on thinking about getting local picknplace/smd quotes but it just gets put further down in the cue of all things to do.

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.

Whats V-series strip?

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?

Surface mounting led emitters the easy way

I haven't seen a tutorial on this here, so here it is. I was extremely nervous about screwing this up and put it off for a while, but it was really simple. I had 100% success with 40 leds. The only tools needed are a multimeter, tweezers, stovetop, and frying pan. A thermometer is good to have...

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

 

[Rocket Soul]

Thx a lot BB but i still dont get the process: thats a strips with leds on it, you wanna de solder it and add other leds? Im liking everything about this but i dont quite get what you wanna do. Seems a lot more advanced than what i thought of. Also, re frying pan soldering, you need a really long pan, and fairly even heat if i understand correctly.

Edit: doh. Reload the thread before i write.
