DIY LED U-Home 3Pcs DC3V-35V DC 3V 6V 12V 24V 35V Variable Voltage Regulator 5A PWM Speed Controller Switch Dimmer for DIY LED Panel Light Single Color LED Strip Light SMD5050/SMD5630/SMD3528

The media could not be loaded. These work great for small projects, I use them to make custom led lights. They are easy to modify

It's simple to connect and operates well with a steady output out of six of them I purchased I had one that did not work. But it's dependable enough that I would buy it again.

I bought this to dim a led backlight on a monitor, and everything should have worked. The power supply for the panel is rated at a max of 4A and 12V which are both with in the spec of the dimmer. I wired it up correctly, and was able to dim the backlight just as intended. Then I noticed the cap bulging and before I could pull the power, BOOM, the cap is no more (and all over my kitchen).

First one died within the 30 day return. The second died after a few weeks of use. Was using at a very low wattage as I was using it to dim my Christmas tree led lights. Worked nicely while it worked but cannot recommend it.
