Need help finding Lm301 H or B led strips

My cobs are getting old and would like to replace them with led strips preferably ones with the highest lumens per watt “lm301”. I’ve tried looking for them on mouser and arrow but get lost in the 100s of pages. Would like to keep the strips at 3500k 2 foot long. Already have an idea for drivers and other hardwire just need help finding led strips

Growdaddyleds.com cheap 96 diode strips even sell some cheaper ones with lm 561c diodes 12 packs best deal. You can find some killer deals on arrow like super cheap discontinued real Samsung strips if you feel like looking up part #'s all night but you can get some good deals.

You can also buy your own diode and have custom strips built by a few different companys, Adura is in California they're the company who makes sinkpad anyways all different shapes and sizes, but there is minimum orders it would be cool to do a group build

Are you going to repurpose your drivers?

The Q-series suggested be @MedicinalMyA$$ is a really good deal, less than half the usual price.

Another good choice is the newer Samsung H-inFlux series where you can get a lot more diodes per strip and minimize how many heatsinks you need.
I recommend:
L06 - FV 24v - 88 diodes- 560x24mm
L09 (double row) - .fV 46v - 128 diodes - 561x41mm

Scroll down a little and click ''Show more specs'' to open table with each model and available CCT with parts numbers that can be searched at Octopart and electronics vendors like Digikey and Arrow.

Not sure if I can repurpose the driver, Its powering CXB3590 cobs at 36 volts atm. Guess it depends on the strip

You can use the Samsung Engine Calculator to find the diodes used and part numbers of their strips. Then use those part numbers to search at Octopart and it will list prices and links.

I think maybe the only ones that use the diodes you want are the H-Influx and Q-Series strips.

These Samsung Q-Series 560mm LM301B 3000K are only $2.50 at the moment.

Engine calculator is way above my head. About the only thing i can match up now is driver/voltage/amperage to the strip . Havent the slightest clue if i need ceramic, array, flux code etc. However I am looking for 3000k-3500k latest gen leds wattage around 400-500 watt

STill a bit higher than a commercial bar with driver ive been looking at. Kingbrite x55 480watt full spectrum contains 1344 Lm301H diodes for $320.

Which driver is it?

If it's a Constant Current driver (serial wiring) it's possible to match many different strips to it.

However, if it's a Constant Voltage driver (parallel wiring), you'll have to find 36V strips, I don't think Samsung makes any of those but I bought some from Cutter Electronics (AUS) a couple of years ago.

If you buy the bare strips you can mount them on aluminum angle iron
You can run em at least 30 watts each I have a few diy fixtures I used those strips, I'll take pics later

The only one I still use at the moment is 10 strips mounted on a triple qb heatsink with 10, 3w 660nm monos on the same channel works out great with a lrs350 24vdc power supply not so efficient but cheap as fuck

This is exactly what I have in mind. What are the temps on the strips? How do you attach the strips to the aluminum, tape or cpu paste? Cobs I’m running now are very hot with passive cooling however they have lasted 7 years. IDE imagine strips would last even longer since heat is spread out

I couldn't tell ya on temps, cool to the touch like barely warm, if you buy 1.5" aluminum 90° angle bar cut 4' lengths it'll hold 3 strips @ 90 watts a lot cooler than the heatsinks they sell on their site. I always use thermal tape with those
