OK, so still waiting for a seneye USB power adapter to be shipped so I can get some actual tank readings from seneye light meter. I've tried it in the office connected to desktop and got the pics below and seneye seems to be working.
Hunting around for a laptop. The WiFi adapter would be the ultimate way to send data from tank to computer but that will be next Xmass.
First slide is of the light meter with the office light. It shows (I think) a plant reference (as thick line) and human eye reference (dashed line) against the actual light readings (white/grey line). So it seems to show PAR, LUX and Kelvin (right side in box) plus the actual light spectrum which seems pretty nifty. Er, if that makes sense?? This is all new here.
This is the reading (white/grey line) and PAR/LUX/K
from office light only.
This is office light plus torch.
This is of the LED
light from the mobile shining right onto the meter.
