Please do NOT use my photo as a reference, these pictures were taken when I was learning how to use it. It is a learning process to those who are not familiar with working with this kind of stuff, and you have to be very careful. Please do NOT work with these while it is plugged it please. I am very pleased with how these turned out! I bought two of them and I am joyful to know that my led strips work fantastically! It is very easy to screw down the wires, there is no need to put it together, you just screw down the wires and you are good to go!I would like to add that I really like how they come with an orange plastic flap that keeps the wires and the screws protected, it is an admirable safety measure that made me feel more at ease when I first started using them. I was terrified at first! 🤣The labeling above the screws are also a good help identifying what each purpose of the screws are, like which one is for the positive wires, which one is for the the positive wires, so on and so forth. I still have some things to learn but this was a nice start and I would recommend this to anyone who is in need of a power supply like this!

Used to power a string of LEDs around my projector screen. Amazing! Good valve for how strong this power supply is. Nice and quiet too!

The power supply works great and added it to a single ESP32 controller with WLED (v0.14.0) in a 5 multi-strip configuration (325 leds total). Everything works great now but had to troubleshoot to get it there.Having 2 output nodes, I originally split the power from the power supply with one going to the controller and the other to the LED strips. Running 1 strip was fine but when I reached 3 strips or higher, I would get random flicker on the last 1-2 strips. (Last being defined as the last segment in WLED). Everything was fine if 1 strip was powered at a time. I resolved this by only running power from 1 node pair from the power supply to both the ESP32 controller and the LED lights. Power being split between all 6 devices (controller + 5 strips) from the power supply. LED power did not go through the controller, only data. That resolved the flickering issue, and all 5 strips now work perfectly. I'm not an electrician and don't know the root cause other than assuming that a power fluctuation occurred that was enough to create interference.

Purchased 5V 150W version to drive WS2812 LED light strip. With only 180 LEDs = 60W max was seeing voltage drops to under 4V as LEDs go from dim to bright. After realizing the hidden switch was set to 220V and correctly setting to 110V it is now regulating the voltage fine. it's a little hard to tell where the switch is set without opening it but you can actually get to the switch with a small screwdriver poked through the holes in the case. However this is the ventilated, non-fan version.Continuing to test. May revise rating up or down based on how this holds up. I plan to ultimately drive 140W of LEDs which is still well under the 80% rule but I'm already seeing this getting warm under 60W load. Not sure about longevity. Would benefit from a fan I'm sure but for my application I need a nearly silent power supply.

Ran it from 0 to 5 amps to see if the voltage would vary. It didn't. I needed to know because I wanted to power an Arduino via the 5V in which goes directly to the chips on the Arduino.

BTF makes a lot of great products for LED projects. I have never had an issue with anything I've purchased from them and I have a few hundred feet of different leds and several drivers now including this one, all have performed great. Even outdoors in less than ideal conditions(not recommended)

Used for my lights and this power supply remains constant even in the Texas heat of winter.

This product is perfect to power WS2812 strips. I've used it for roughly 3 months, powered on nonstop, and it's so good I bought several more for future projects. When I had a slight issue with one, customer service fixed my issue almost immediately and went above and beyond!
