My SolStrip samples arrived last week. So far, they are testing well. Highest diode density of any strip or board around using the Samsung LM561C chips, 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.
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.
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.

- 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)
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.
