I'm renovating a bit again and in one place I want to provide lighting via a LED strip mounted at the ceiling corner. That will be 3m of LED strips, and I'd like the place to be well lit, so I'm aiming for 1000lm/m or above. That then equates to slightly less than 15W/m or 45W altogether. The nearest power supply that I see is 60W. I want to tuck this power supply out of sight - and I have a place for that, but it is also at a ceiling corner - and will likely be covered with other stuff (it's a storage area), so I'm a bit worried about heat buildup.

Another worry I have is that very close to that place I intend to put my wifi router. How electromagnetically noisy are these power supplies? Is it likely to interfere with my wifi signal and should I make faraday cage to put around it? Or is that overthinking it?

So, to recap:

  • Do I need to worry about the LED strip power supply overheating?
  • Do I need to worry about EM interference with my nearby Wifi router?

    These are two very different questions (even though they both relate to your current project) and should be asked separately. – FreeMan Mar 04 '23 at 00:14
  • AFAIK the power supply will only provide what the lights draw. If you provide a 1000W PS, your lights will still only draw 45W, and the PS will only provide 45W. If you provide *less* than 45W your lights may be dim, or not work at all. – Huesmann Mar 04 '23 at 14:17
