First post, read through a couple of different threads trying to find an answer but did not find quite what I was looking for.
Was installing a new set of under cabinet LED lights this evening and all was going well. When I tested, I found one of the light bars was considerably dimmer than the other. Initially I chalked it up to a bad light bar but my wife persisted in berating my work and convinced me to prove that my wiring was good.
The wiring was fairly straight forward, there is a junction box in front of the light bars to accommodate a two wire plug, instead of plugging the light bar directly into an outlet. As a quick test, I took one of the other brighter light bars and plugged it into the same junction box, the light bar was as bright as expected. Still not convinced, my wife asked that I check plugging directly into the wall with the included wire. Surprised, the previously dim light bar lit up to full strength.
Perplexed, I busted out my volt meter and checked voltage at the non switched/dimmed outlet, it read 120V as expected. I then checked the junction box and was surprised to find that the voltage was reading 109V. I toggled the on/off switch and adjusted the dimming level, each time it read a max of 109V with a low of about 57V.
So... My question and/or reason for discussion is simple, is it expected to have loss of voltage simply by introducing a dimming switch, even when adjusted at "high", or do I just have a really shotty switch?
In either case, how would I identify a quality dimmable switch that is rated and/or capable of outputting 120V in it's fully on state?
