Lumiled Luxeon SunPlus 35 - 12.5% blue purple strips

So with Lumiled Luxeons new SunPlus line of chips I'm wondering if anyone thinks a PCB strip with 100 x L1SP-PRP1003500000 (12.5% blue purple 5630) would be good? How many strips of 100 leds would cover a 4x4? Each strip would be 560mm long

Depends on how hard you want to drive them what light intensity you're aiming for.

Let's say you want to reach 800 µmol/s/m^2 average @ test current
typical photon flux per LED @ test current = 0.58 µmol/s
area = 4x4 ft^2 ~ 1.486 m^2
needed photon flux = 1.486 m^2 x 800 µmol/s/m^2 = 1188.8 µmol/s
# of LEDs needed = 1188.8 µmol/s / 0.58 µmol/s ~ 2050 LEDs
Optical losses are not included, obviously.

Thanks heaps for the technical breakdown I would be running these strips along side 3000k strips to try cover the spectrum fully.

I've got a quote for 560mm ALU PCBs with 100 chips on each board, I was thinking 3-6 560mm strips over a 4x4 in between 1120mm 3000k Samsung M series C strips. Whatre your thoughts on this?

600 of those running at 50% rated current would produce 667PPF and ~350watts of power to run. 1.86 umol/J

May I ask where you're getting the PCB's for these? I've been looking myself to find this for lumiled sunplus line.
