    First thing to do is check the 24 strip is dimmable (I think some are only on or off) then I would just phone aten to get an idea of what total wattage of LED's are advisable in a m/h of your size I think it would be daft to fit them if they are constantly going to be dimmed right down or how this would affect the life of them and the dimmer/the power used/any risk of overheating/the cable size needed at 12v to the converter etc. I recon I must sound a right eyore but when I do a project its sometimes useful to have any drawbacks considered at the start so good luck with it all.

    i find leds are best mounted facing away from your eyes so the light is reflected

    I have similar system, spoken to @Wissel on another forum, but I do have a thread here about my system. I went with LiFePO4 too as I’m a full timer, it is definitely recommended.

    Yes. Ironically it's the better ones with switch mode control that probably won't be. You can feed them 10-24V and the light will be constant but the current decreases as the voltage rises, which comes as a shock to see it for the first time. This mainly applies to the bog standard bulb replacement modules.

    The aluminium LED cases in mine are installed in the ceiling but I could only use ones that have roughly 8mm depth. So that is why I’m having a problem. It’s not directly facing towards my eyes but I could slightly see the spots and it’s pretty annoying. I was wondering if there is any diffuser material that I can put in between the LED strip and the plastic cover that would help and does not catch fire?

    How long is the strip you need?
