Rider's first foray into LED strip lighting: Samsung H Series GEN3

Scrogdawg said:
I might be confused Rider. My mind is thinking 8 of the Samsung LED strips you have together makes one panel????

That's the configuration at present, but since each strip is on its own Al u-channel I can split them up and play with coverage patterns or add and remove strips to work with different drivers.
 
I mounted the four double row F Series boards on two 45" Al u-channels for ease of testing, but left room to be able to cut them in half later.

It's deceptive because the camera adapts to the amount of light, but I can tell you that one glance at them and you have 288 white spots burned into your retinas. LOL

Do they mount to the Al with a double sided foam adhesive strip or the likes? If you loose a diode do you loose the whole strip? Can you replace individual diodes?

Fuck, I can't believe how ignorant I really am to LED's. It's a little embarrassing to say the least.
 
The MTBF is crazy high so it's not something that concerns me. And yes, you could replace a single LED. It's really not that hard even without the specialized equipment. The soldering specs are on the unit data sheet. The higher output LED strips, boards, and COBS that we're interested in are designed with series/parallel configurations on the PCB. This'll give you better insight than I could create.

What the above doesn't tell you is that if a single LED fails open then that string is eliminated from the circuit and all hell is going to break loose if you're running close to the design max. LEDs perform best when driven well below the max, i.e., more lm/W, less heat, less chance of catastrophic failure.

I used an adhesive heat sink tape to secure the strips to the heatsinks. You could use the two-part heat sink epoxy but that just seems too final to me.
 
I'm at odds with some LED guys that advocate running LEDs gently. I get that the LEDs are more efficient at lower driving currents, that they'll have a longer lifespan (typically 50,000 hours), that they'll run cooler, etc. And that's cool if you want to maximize longevity and count pennies per watt. But I'm not a guy designing lighting for a high-rise office building. I'm a guy wanting to wring every lumen I can out of these lights. I couldn't care less if they can go 50,000 hours before age-related failure if driven softly. I don't care if they die in half the time as long as they're burning as bright as the fricking sun before they die. 50,000 hours is 5.7 YEARS! Who the hell cares about making their LEDs last 5.7 years! I'll be on to the bigger better badder offerings the future holds way before those lights hit middle age.

That being said, the LED strip and driver combinations I'm going to be testing adhere to the less is more philosophy. But after testing I'm going to drive the bloody hell out of them... that is if I can ever get one of these f*cking Hawaiian Mutt seeds to germinate. I'm beginning to think there's a guy in Hawaii laughing his ass off over the seeds that he baked at 450F before gifting them to me. I'm beginning to feel like Fanleaf did with his 42 year old Acapulco Gold seeds. LOL

Keep in mind that the testing on the Samsung HB22D strips are 5000K, not 3500K. Maybe someone whose brain isn't fried can extrapolate those numbers to expected outputs with 3500K strips.

PAR output testing results will follow in a day or two.
 
So far it's easy to see that the double row Samsung F564B leds run hot, as expected, and aren't as efficient.
Given the desired output of 50 watts per foot square over a 1x4 space it looks like the HB22D system driven by a 185H-C1050 is the most cost effective of the bunch. I'd probably opt for the A version of that driver. I'm not ready to declare a winner yet because the proof is in the PAR. I'm also waiting on a couple of HLG-600H-48A constant voltage drivers to arrive for testing.

One drawback on the 44" led strips is that they barely fit inside a 4x4 tent.
 
With costs. Costs are in USD and are exclusive of shipping, taxes, and frame/finishing components. For reference, I bought 32' of 3/4"x3/4"x 1/8" aluminum u-channel for $32USD at a local metal yard. I'll let you draw your own conclusions here.

Damn! I hate to admit that I was wrong.
 
XD im just waiting for someone to come along and paraphrase everything as someone often does .
 
I just completed a test run by wiring two 564s in parallel, effectively duplicating a FB24B strip. I ran two of those psuedo-FB24B strips on a 320H-C2100B and they held right at 65C. Three of the FB24B strips wired in series and that driver are an excellent match for output and longevity, and pump out almost 300 watts. That puts about 37 watts per square foot over a 2x4 space. With the A version of that driver you could get a little more. Good bang for the buck, coming in at about $230US. With three of those systems over a 4x4 you'd be hitting about 56 watts and could dim it down and have headroom to spare. That's close to 900 watts at the price of 550 watts from an eight CXB3590 COB system with the same drivers, and you get a much more uniform distribution of light. The other driver option, if you'd prefer to wire in parallel, would be a HLG-320H-48A with three strips.

For future expansion on the same driver a HLG-600H-48A would let you start with three strips in parallel at 300 watts and add up to three more for a total of six strips in parallel running at 2.1A each for about 600W. Just remember to set the drive voltage and current using the built-in potentiometers!

The H Series strips are going in my shop.
 
The real deal would be to run four strips in parallel on a HLG-480H-48A. You could run them at 2.5A each for a total of about 475W, and that's still only 70% of the max amperage of the strips. See how quickly I can spend someone else's money? LOL

If anyone is thinking of going with a 480H-48A or 600H-48A constant voltage build and needs help in setting the driver for correct output per strip, hit me up. With a multimeter capable of measuring DC amps it's so easy even a pirate could do it.
