    You mean that you only use one cable down the spine and connect both at the top?
    Yeah I think you can do that without problems...

    120 looks much nicer I think? less 'green' ?

    Yes Alex, that is exactly what I meant. Thanks.

    I should be getting my 24v 5050 60/m tomorrow. So I will post some images of those for comparison.

    As long as I have not blown myself up by then!

    I saw the green too. Dunno if it was just a problem with white balance or the cam has a problem with the brightness and then sucks at white balancing.

    Is that just a trick of the camera then? I think 120 is a good way to go with the Pi camera view by the looks of it. Although you can adjust white balance settings for the Pi so maybe that would yield a better picture?

    The RaspiCam adjusts itself by default. You can override this I think...
    I am not absolutely sure but I will go for 120 for now...
    You're right, the pic of the RaspiCam looks a bit better with 120 thought I am not absolutely sure if it was just a settings problem.
    But the green is in all 240 pics so...

    Yeah, looking at 120@33% seems a perfect balance.

    Update: Should be fitting my 5050 60/m LEDs later. I have tested the wiring with some 3528 and through Octoprint's custom buttons, it all works great. I did note that the 5050 60/m actually draws less power than the 3528 120/m but actually produces more lumens/m is that correct? From what I have read the 5050 is 24v 14.4Watts/m 60LED/m, the 3528 tape I have is 24v 9.6Watts/m 60LED/m (I assume 120LED/m is double-ish) though the 5050 produces around 1000 lumens. Is this correct?

    Sorry I have no exact information about the differences.
    But yeah if you double the LEDs then the power and current doubles...

    Update: I have fitted the LEDs! I have set these to 60 (out of 255) so roughly 24%. Plenty bright enough although the camera settings could do with a little tuning!

    OK, the LED shining through the blue acrylic is awesome. A dim shine through the blue frame would add quite a touch of coolness in addition to the scene lighting for the time lapses...
