The 12v power supply for LED strip lights has numerous strengths to present to a wide range of customers. It's highly energy-efficient above all else, lowering overall power consumption by increasing conversion efficiency. Second, because it makes voltage stable, there's no flicker which extends the service life of LED strips--even those old models that don't offer this feature. Also, the power supply is small and has a minimal profile, thus it can be easily hidden behind walls or in closets to reduce clutter in tight quarters. It's first and foremost a matter of safety; the built-in protections prevent electrical hazards (meaning fewer fires). So for potential customers, that's lower costs, more convenience and comfort all round. Their own lighting layout becomes a solid investment--a way to guarantee its safe operation next year and beyond!
