Thanks for the excellent reply!
According to the spec sheet, the typical voltage is 2.0v and maximum is 3.0v @ 20mA.
I put an LED on an LED testing multimeter, it said 1.85v but it only puts out 10mA so I misunderstood before (voltage drop changes regards amperage, now learnt)

Many thanks for your reply.
50mA is the maximum. I was aiming for the brightest, but for the sake of reliability, I'm flexible, especially if there isn't a vast difference in brightness.
I've read you need plenty of voltage overhead, is 0.9V enough for decent reliabilty?
You say that each...
1080ma to watts
The voltage drop is 1.85v (super bright red) so I'm guessing it should be fine as each row would equal 12v with a suitable resistor?
Would wiring so many in series and then linking each row in parallel and supplying the lot with 12v be ok?
string 9 leds series
I am planning to use a 12 volt regulated supply and two circuit boards, each having 54 LED's.
Each board will have 6 LED's across the width and 9 LED's in length. (simple rectangle shape)
This is where I get stuck.
I've heard LED's can vary from batch to batch so...
