The first part of a video where I swap the driver in one of my bench lights for one scavenged from another light.

In part two I de-pot and reverse engineer the driver to see what went wrong.

Fixing my bench light

One of my bench lights started intermittently blinking off and on, and before it got too bad I decided to swap the driver in it, since it was the most likely issue. If left longer the blinking would have got more frequent until the light was pulsing continuously. If attempting a repair on a similar light, ensure the power is turned off and check the integrity of the earth/ground connection in the light. In this style of light you can use a lower power driver with a higher power LED. I use a 20W driver with a 50W LED. My bench lights actually have a fairly easy life, since they are on a PIR sensor so that they turn on automatically when I approach the bench and turn off if I'm away from it for a few minutes. It's hard finding a good quality driver with proper electrical noise filtering that actually fits in one of these floodlight cases. I opened a few lights, found a couple of suitable drivers and then chose the one that looked better quality. The driver that failed is explored in another video. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- https://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

Would it take you a long time to build your own driver from scratch?

Nice job Big Clive. It's very satisifying to improve one's lighting. Simple fix and good results. High CRI units are the way to go.

I'd take a very simple approach of using a standard current regulated power supply. Designing something to compete with these mass produced modules would be expensive.

The tricky bit is finding REAL high CRI LEDs from online sellers. They like to drop CRI in as a sales-keyword.
