If you are interested in building the larger Quantum Board QB288, all you have to do is the following 21S8P series two modules connected in series for 126Vf 1699mA

1. Use 3 segments of 21 diodes with a Vf 63v @ 200mA
2. Wire 8 strings in parallel 63Vf @ 175mA
3. Make two of these modules and wire together in parallel, l negative to negative, positive to positive, and connect negative to -LED and positive to +LED to a HLG-320H-C1400B driver and you have a QB288 Killer too.
easy

_DSC5511.jpg Well be interested to see how these strips on their own grow are ladies.
I'm looking something for side lighting to run around the back and two side walls in my 5ftx2.5 or there abouts ft flower cab. Currently have 4xqb's in there and running at 400w. Grow style sog and scrog.
Pic below whats the opinion on doing this.

I think you will find quantum boards elsewhere this is not a thread on quantum boards in case you have not noticed flexible strips not side lighting if you need side lighting perhaps you need better lighting with penetration

This is a thread on DIY Samsung strips not quantum boards go sell quantum boards elsewhere no selling here allowed build your own not buy quantum boards. Stop trolling with your quantum boards having sales issues need more advertising. Not interested in quantum boards thank you

Is known what voltage binning is used in these strips? There are three, A1, AZ and AY and the difference is about 10mV between each bin.
With 336 LED's for instance, each next bin would add ~3,36v or ~4,7w@1,4A.
9,4w difference between A1 and AY is a lot.
Do you know the voltage bin?

My SolStrip samples have arrived. So far, they are testing well. Highest diode density of any LM561 strip or board around, 1.25 cm2 per diode. But the real value is their flexibility in DIY builds, allowing me to choose the density and arrangement that I need for the space I want to light.

SolStrip 1.0.png

Specs:

Size: 400 mm x 30 mm (15.75” x 1.2”)
Power: 48 watts, constant current, no resistors
Output: 9000 lumens

LEDs: 96 diodes Samsung LM561C top bin
CRI: 80 (S6 bin), 90 (S3 bin)
LED Color Temperature: 3000°K, 4000°K, 5000°K (2700°K and 5700°K tba)
Efficacy: 161 – 212 lm/w

Power Consumption: 36.8 to 48.4 W
Operating Current (If): 2000 mA
Operating Voltage (Vf): 18.4 to 24.2 Vdc

Luminous Flux: 7200 – 9000 lm based on Samsung spec
$10 lux meter test: 8980 lm2 @ 12”

PCB: Aluminum on 2 oz. of RA copper core
PCB thickness: 1.6mm
Thermal conductivity coefficient: 1.5
Mounting Options: M3 screw holes, thermal tape
Electrical Connectors: 2 x 18-20 AWG push-in 2061-2-2P

Application Environment:
• Lumen Maintenance: L70 = 7 Years
• Min. Ambient Operation Temp: -40˚C
• Max. Board Temp. (at tc): + 85˚C
• Max. Board Temp. for life rating: + 65˚C
• Max. Current Rating: 2.8 Amps

Compare to:
- Samsung H Series H22D x 2
- Samsung H Series HB562D x 4
- HLG Quantum 288 chip board (3 Q-Strips)
- Photon Fantom 240 chip Sunboard (3 Q-Strips)
- Cutter Sol-Skin 594 chip board (6 Q-Strips)

Three to five of these fit nicely in a half-size commercial baking sheet. I'm working on a DIY design based on the baking sheets - best aluminum sheet value out there, and the 1 inch rim makes an effective reflector for redirecting stray photons.

SolStrip 1.1.png

Cheap-o lux meter gives 8980 lux at 12" on one strip at 24v, 2A. Almost 19,000 lux at 12" on the 3-strip sheet at 24v, 6A.

SolStrip 1.2.png

The Mean Well HLG-***-24 line will work well with these strips in builds - just pick the wattage you need, 48w per strip.

Will test these 4000k 90 cri samples before placing a full order. If they check out they should be very competitive to existing Samsung rigid PCB options. The manufacturer provided proof of chip authenticity down to the chip lot number, so I'm pretty sure these are the real deal.

A big fat "like"! Looks like the estonians but with samsung diodes.
But if you place an order ask him for the AY voltage bin. A1 is the "badest", 20mV gap between A1 and AY, with 96 diodes this quickly adds up to 1,92v more.
 
Did I miss class one day? Where did you order these from if you don't mind me asking Baudelaire. I searched Alibaba for SolStrip and got zip...

What was the price @Baudelaire ?
When it says operating current, is that just what the other data is based on? You could in theory run them at considerably lower amperes?
These were custom designed and fabricated, you won't find them on Alibaba. Minimum order amounts are in the hundreds, I'm trying to get a sense of interest here and then go back to the manufacturer to get volume discounts. But early indications are that in sufficient quantity pricing will be sub-$20 per strip. For those interested I've started a SolStrip thread HERE, please use it or DMs for pre-order questions, I don't want this thread to get derailed.

Looks like the estonians but with samsung diodes.
But if you place an order ask him for the AY voltage bin.
I have the Estonian strips and like them, I used them to model the SolStrip design. The SolStrips are 2x as powerful and about 15% more efficient.

I am sorting out the voltage bins with the manufacturer, who seems genuinely bewildered by my fixation on chip generations, efficacy, bin lots, and color rendering indices....

I am glad to hear that happier you started a thread about your design. But anyone is welcome to do as you like on my threads no respect is your behaviour enjoy.
