Hi All,

I was hoping someone can help me out. I have a ten year old path light that died. I was hoping to fix it. The leds look like they can be removed. Any idea what to replace them with? There are a total of 4. Thanks!

Nick

Those LEDs look like a midpower LED soldered to a carrier board, and then the whole thing covered with a glob of encapsulant. As the LEDs are on carrier boards, plenty of options assuming you can get the old LEDs and boards off the fixture. Just make sure you get the proper voltage alternative parts - those midpower packages are available in a range of voltages, the most common being 3V, 6V, and 24V nominal. Drive current is also pretty low for those packages, typically under 200mA for the 3V versions and correspondingly lower for the higher voltage parts.

Thanks. I'll have to do more research. I think I can get the leds off, I'm just not sure what to replace them with. I'll have to see if I can figure out the voltage and drive current.

What are the lamps rated at (watts)? That's a start. Do they run on 12v? LED power class will be spec'ed power per lamp divided by four.

I've just opened up one 12v 4W low-voltage garden spot, obtained at a huge discount (I use solar, but not wired, outside). Quite interesting driver is inside.

If you can get access to LED terminals of a working unit, measure LED forward voltage. Spec'ed power divided by voltage will give you total current for all LEDs; divide by four for current per LED. That will narrow things down.
