Powering 20m (4x5m) White LED strip from single Shelly RGBW2

    Hi,

    Does anyone out there have experience of powering 20m of LED strip from a single Shelly RGBW2?

    I have 4 x 5m white 24V LED strips that I want to power from the Shelly. Each strip is 11.2W/m (56W per Shelly channel). The Shelly specs state it can handle 90W per channel at 24V, so it would appear I am well within spec, but I have read lots of stories about Shelly devices overheating. I'll be using a 320W 24V PSU.

    I was wondering if anyone out there has already done something similar and what their experience was.

    I have found good success with powering >15m of 24 V LEDs from one end with no additional gear.

    The RGBW2 is fed from quite a chunky transformer, and I will never need to crank the LEDs up to full power. Still it's very encouraging so far.

    Our RGBW2s are mostly in a power cupboard / room where they can easily dissipate heat. Only a couple are fitted behind a light switch (because the installing electrician messed up). I can see that they might struggle to dissipate heat. Those two in particular will be working at way below their rated output because they just provide light to a small room each.
