I basically have 8 of them individual RStrips (complete with the heat sink) so twice as many as your fitting holds, in a custom configuration to fit into a 2x2 between the loft beams so it will be interesting to see how they compare. My main concern is that I didn't receive a dimmable driver so only have the limited inbuilt adjustment rather than an external potentiometer or full PWM control.
Just seen you have a grow diary for that Wedding Gelato (Minty fecks off to read that...)
