12vledpolarity
Hello all. Thanks for the forum.
I have some of these: G4 bi pin LED bulbs. Silicone coated dimmable 12 volt DC. They are 1.5 W.
Although not visible on this photo, the pins are marked "C" to the left and "P" to the right, when viewed with the pins lower most. Eveything else about them appears identical.
Could anyone confirm which poles they signify?
Or are these bulbs not polarity dependent?
I am a novice. I have a 24/12 volt solar system and I am designing a small set of chandliers.
Since the product you purchased has no background information, you can't be certain. However, the convention for these stacked-disk type capacitors is polarity mark points to negative lead. This is the same as is the convention with conventional electrolytic capacitors.
For example, the Eaton KR-5R5V474-R:
Has its datasheet show:
Similarly, for the Panasonic EEC-S0HD224H:
Has the same arrow convention considering the asymmetric leads with polarity indicated in its datasheet:
You can't draw in "comments", so here is an idea circuit that might get you going in the right direction. You can put as many LEDs in series as you need and you may have to play around with the resistor values. Two potential problems: the pot may not be linear and you have to turn the pot in the opposite direction from where you are now to dim.

It won't matter which pins you choose as the other side of the photo has 2 more diodes to make a full wave rectifier so it can operate on Vac or any polarity Vdc for the voltage rating given.
P and C could mean something to the factory for assembly process controls but is not useful to you.
