JMWaaBong Switch Mode Power Supply 400W 12V 33A Constant Voltage LED Driver 12VDC Rainproof Outdoor 110V AC to DC 12 Volt Transformer Converter (FX400-H1V12)

hello there boys and girls what we're looking at here today is a simple circuit for an LED lamp that I want to make so I bought these components on light in the box very inexpensive and we're looking at here is a little transformer it's going to convert the AC power to DC and I've got a quick clip on here to a g4 plug so it's going to power this LED lamp no more about that later so what I've done is I just connected a extension cord hooked up a little light switch to it just so I can experiment turning it on and off and made a simple circuit like I said I'm gonna make a lamp out of this and I want to be able to plug it into a regular power cord using AC 120 volt egde so what we're looking at as far as the transformer cut this from light in the box it's a really cool important place from China it has all kinds of LED lights and circuits and what this is is a constant current power supply
