Your 12V LED strip is running hot, the colour's drifting, and the brightness isn't where you set it. That's a driver problem, not a strip problem. This Mean Well PWM-40-12 delivers a steady 12V at 3.34A — 40W of constant-voltage output that keeps your strip's colour temperature and brightness locked in. Dimming works by adjusting the PWM duty cycle, so you get a clean fade instead of a choppy strobe. Compact enough to tuck behind a kitchen bench or inside a shopfront valance. No guesswork on the wiring — it's a plug-in-and-go driver for 12V LED strip runs up to 40W. If your current supply is undersized or buzzing, this is the fix
