I got so into experimenting with LED lighting and modifying light fixtures that when I was offered a product to test, I couldn't resist and decided to try a factory-made LED driver. If you're interested, read on to see how the idea developed.

In my previous review, I wrote about an ammeter with a display. This time I decided to take a look at a voltmeter bought from the same seller.

I’d been wanting to pick up a small ammeter and voltmeter, in a form factor suitable for mounting in a panel or plastic enclosure. I chose them, ordered, paid, and received them—in other words, nothing unusual so far. Now it’s time to take a closer look at what arrived. First, the ammeter.

It all started when I got tired of replacing bulbs in small light fixtures. I decided to get to the bottom of the problem—maybe not forever, but at least for a long time. Read on to see how it turned out.

I've published several LED reviews, so it's time to write about what you can use to power them. This review covers three components (links and prices included), all of which are needed for one purpose: building an LED driver.
