We have to change the lights in my tabletennis club. We are going to put up around 50 panels in 3 strings Each panel is 40w and 24vdc. I was wondering what the best and most cost-effective way to do this might be.

One of the things I was looking to do was to get a single driver for several panels. Maybe a 200w driver for 5 panels? But would it then be better to do it in series with 120v or in parallel. And should the driver be constant power, or?

I will appreciate any and all help!

    Ah gotcha. Yeah as an American sparky, we don’t see those external drivers much. Most LED lay-ins are dimmable right out of the box.

    Outlets themselves are usually less than $1 apiece, but if you wanted to you could just cut the plug off and wire them directly to your hot and neutral.

    I don’t know what would be most economical for you to be honest.

      Ah, outlets are around 15usd for the cheapest here and look like this:

      And then we need the box, which is also around 15usd.

      So maybe 1.500usd, which is quite a bit of money for us.

      The thing is, regulations don’t allow us to simply daisy chain mains voltage without one of those outlets for each link - except maybe if the driver had daisy chaining in it, but I can’t seem to find one.

      This is why I was hoping to maybe find a driver that would at least let us daisy chain 5 or 6 panels, since I’m allowed to do just about anything I want with DC, it is hardly regulated.
