I want to make the brightness adjustable on a Milwaukee 28volt worklight that uses li-ion batteries. Any ideas for this odd ball voltage? Thanks:o

Seldom a problem using a higher voltage rating device.

LOL Isn't that the light in the new 700 dollar combo kit? I would shake to start modding that!

Yeah, that's the one. LOL is right!

To be honest with you, that doesn't seem like the kind of question you'd get a satisfactory answer for in this forum. You see, around here, we usually deal with HVAC (High Voltage Alternating Current) - i.e. wiring meant for 120 or 240 volts, with applications generally found inside the walls of homes and businesses. You are dealing with LVDC (Low Voltage Direct Current), which is a completely different issue - for example, low voltage is not lethal, it is meant for portable applications, etc.

A good example of why you may actually find better advice elsewhere is that there may be a solution out there to your question that involves using semiconductiors (transistors, resistors, etc.) to build a logic circuit to control the brightness; but that is not the kind of info commonly found here (that kind of info is more like "science fair" stuff than the kind of work an average electrician does). You're probably better off checking a forum that deals with "Radio Shack"-type issues, if you get my drift (i.e. "Hobbyist Electronics" as opposed to "Electrical Wiring").

Whatever you decide, good luck.

PalmMP3,
Moishe, Thanks for setting me straight. Wasn't sure where to go.

No problem. That's what we're here for. ;)

Good luck!
