This was a real beast to get apart. I thought the screws on the front were going to release everything, but there are a significant number of plastic sections that clip tightly together.

I cobbled together a simple mains driver to show the LEDs in one module glowing at low level so we could count them and see the internal construction.

Once again, I ordered one, but two turned up! I don't know if this is an ordering glitch or some weird promotional stunt.

Huge 30W ceramic core LED light (with schematic)

One correction to make. I said and wrote 220uF for the main capacitor instead of the actual value of 22uF. (I was already thinking about the parallel 220nF capacitor when I did that.) Just like the other lights made by Sansi, this was a beast to get apart. Lots of plastic bits tightly clipped together. But once it was apart I could see the logic behind their assembly process. The main feature of this lamp is the custom ceramic core LED modules to help take the heat away from the LED chips. There is a bit of redundancy built in as three parallel sections of 12 LEDs are used per module. The buck driver is a classic type found in many LED lights. Each module has a voltage of about 36V at about 160mA. I bought this from a UK-eBay shop, but they appear to have eBay shops in other countries too:- The price has gone up significantly since I bought this one. https://www.ebay.co.uk/sch/i.html?_ssn=sansi_eu01 If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty. #ElectronicsCreators
