Samsung F Strip Build

iPerculate said:

@CaliWorthington I would highly recommend the F strips, 144 diodes on the 2 foot double row strips. May only be a couple week lead time but you never know with the shut down status.

The H influx L09 strips with LM301B strips are also pretty nice but more expensive. They have some 1 and 2 foot strips in that family in stock.

Some pics from topping them today, poor girls.

So that's the LT-564B huh. 168 lm/w (typical not max) compared to 126 lm/w on the $5 strips. That is pretty significant I guess.

I just ordered some bigger drivers, to run my strips at higher current in flowering. I see that the F strips go up to 1.8 amps max, 1.1 amps typical. An HLG-480 can run 6 F strips at 1.66 amps, or 9 strips at 1.1 amps. I see you're running yours at 1.1 amps.

LT-564B is correct. Maxing out my HLG-320 driver on 6 strips gets me 1.3A on each. At that level they are bright as shit and still run pretty cool on heatsinks.

SL-B8V4N90LAWW is an example of H influx L09 series.

Nice. I checked your first post on page 1 and saw you were using an HLG-320, so I edited my post before you posted. Anyway, I'll have the drivers to run $5 strips or F strips at 1.1+ amps now.

Nice. I would always try to lean towards running more strips at lower wattage if you can.

Just a heads up......
future electronics currently has stock of eb gen 3 , 4ft , 2700 , 90 cri.
Increments of 20. Just got 20% off as well. Came out a little over 9$ a piece. 8$ shipping. Damn, waiting soooo long for these 90 cri, finally.
They also have some other kelvin and sizes in 90 cri.

Happy hunting!

Nice, hope the build goes well. I scooped up some 90 cri 4000k 2ft's a couple days ago. Missed the 20% but came out to 130 to my door for the 20.

Yeah beats the prices at digikey without a discount so I got 20 and some drivers for them, thanks for the heads up.

@TreeFarmerCharlie How did it go trying to drill and tap between the fins on heatsinks? Do you have any pics more pics of the build you could post?

It didn’t work as well as I had planned, because there was no way to snug the T-Nuts down once I slid them into the rail because the screws were too short. If I were to do it over then I would still go with T-Nuts, but I would drill through the heatsinks & countersink the flat side of the heatsinks, and then screw them from the flat side with a countersunk screw before mounting the strips. You could also thread all the way through and use long enough set screws that would be able to hit the rail to hold them in place. My issue was the only set screws I could find locally were Barry long enough to hold the heatsink to the T-Nut, so I used a glue that dries clear (and can be removed) to prevent the strips from shifting.

Looking at the specs, the H series are a little more efficient than the F series. F series strips have higher luminous flux, which I think means they're brighter in the human visual spectrum. That doesn't matter to plants, though. I'm tempted to go with H L09 strips for my next build.

The plants seem to be loving the new lights so far. Top picture is with the old lights, and bottom pic is after being under the new lights for 2 days. The nodes are growing much closer together and I’m getting a lot more leaves.

The SL-B8V7N90L1WW are showing as being obsolete suddenly on Digikey Canada. Maybe I missed that before.

and Heatsink USA has started to ship civil orders as of today.

I didn't realize H-series have less diodes. That explains why F-series have higher luminous flux. I would go for F-series after all.

Has anyone received their order from future elec? Or received confirmation its being delivered? In particular the 90 cri.
They screwed up my order and cancelled it and then sold out of the strips. Now im reading on another forum they may not have had the 90 cri to begin with. May have been an labeling error. I have not seen confirmation of this yet.

Also note the eb3 at future seem to be different from the Eb3 Slim line at digikey. Different datasheets and different specs. The slim line is .5 inch wide whereas the eb3 series is almost an inch wide. Keep that in mind when shopping for heatsinks.

I've not tried ordering strips from them yet, but I got my MW driver from them last week and they were great with keeping me updated. They wound up being out of stock on the driver and I got calls over the 10 days they were waiting on stock to let me know what was going on.

They do have responsive customer service. I was just unlucky with some technical website issue. It happens.
Another member confirmed he received some 90 cri from them. Hopefully they get more stock.

Yea, I got mine in like 4 days from placing the order.

Hello peoples, I have made lights for a 2x2 and a 4x2 using EB Gen 2 560mm strips following the plans at https://ledgardener.com/diy-led-strip-build-designs-samsung-bridgelux/ and a little while back I went to buy 24 of them for a 4x4 light but they were sold out at Digikey and Arrow, then I read this thread, got excited and now I have 24 of the $5 LM301A strips. I don't trust in my ability to design lighting circuits so I waited until the EB Gen 2's were back in stock and followed the Ledgardener.com plans and built a light for a 4x4.

I don't really want to waste the $5 strips so if anyone can help with a wiring design and driver selection for another 4x4 using the $5 strips I would really appreciate it. Was originally thinking all the strips driven at half nominal power (700ma) because I scrog with the EB lights practically a few inches from the canopy and it's been working really well for me, and also for temperature control.

I just got a HLG 320H 48B for €15.50 and €45 shipping . Shopping was that much because it was from Italy to UK. It arrived today. I thought there was something dodge but it looks to be all ok. Happy with that. Now to wait for my heatsinks 2moro

I now have my HLG320H48B driver and some sexy looking heatsinks that maybe a little over kill, but will make my light nice and sturdy and very easy on the eyes. 3000k 3500k 4000k L09 strips that I will mount. I know there are better strips out there but are they going to make my electric bill that much more? The difference in the new and old,, how much are we talking? It surely can't be that drastic considering I'm only running 320w with them.. now say if I was lighting a whole room, that's when it would benefit getting the best strips surely?

Here are the heatsinks anyway.
