LRS-350-12

Review: Rock Solid Power for My xLights Christmas Display! - The go-to power supply for serious Christmas light enthusiasts If you're in the xLights/pixel light community, you already know Mean Well is the name to trust – and the LRS-350-12 delivers exactly what you need. My setup: I'm running a Kulp32 board and using FOUR of these power supplies to power my house Christmas display. They've been absolutely bulletproof through the entire season – rain, cold temperatures, hours of run time every night – zero issues. Why these work so well: Clean, stable 12V power keeps my pixels running flawlessly 29 amps gives me plenty of juice for multiple pixel strings Compact size makes mounting in my enclosure easy They run cool even during long evening shows No flickering, no weird pixel behavior, just reliable power For the xLights crowd: You know how frustrating power issues can be when you've spent hours sequencing your show. These just work. Set it and forget it. I don't worry about my display mid-season anymore. Quality build, reputable brand, and priced right when you're buying multiples like I did. Already planning to grab more for next year's expansion! If you're building a pixel display, don't cheap out on power supplies – grab these.
Review: Bulletproof 12V Power – Runs Cool and Never Quits! - I’ve been using this MEAN WELL LRS-350-12 power supply for about six months now to run a big LED strip setup in my garage workshop, and it’s been rock solid. I’m pulling close to 25-26 amps continuously (around 300W) with multiple COB strips and some fans, and this thing doesn’t even get warm— the built-in fan kicks in quietly when needed and keeps everything cool. Hooked it up to a terminal block, adjusted the voltage trim pot to exactly 12.0V, and it’s held steady ever since, no ripple or droop even under full load. The build quality is typical Mean Well—thick metal case, good screw terminals that grip wires tightly, and all the protections you want (overvoltage, overload, short circuit). I originally bought it because my cheaper no-name supply kept shutting down and overheating on the same load. This one just works, day in and day out. Super reliable, quiet, and efficient. If you’re powering LEDs, a 3D printer farm, CNC router, or any project that needs a solid 12V chunk of power, you can’t go wrong with this Mean Well unit. Already planning to grab another for my next bench.
