I replaced some halogen bulbs in my recessed cans with some LED retrofit kits I also replaced the dimmer with a new digital LED dimmer. When I dim the lights down to a low-ish setting, I can wait about 45 mins and eventually the lights will be off. I
Are these the the type of motion sensors which use the neutral wire? A motion sensor needs power to work. Ideally it gets always-hot, and neutral, and then provides a switched-hot to the target bulb. Such a unit should work fine, I use them widely
The Tospo is a cheap Chinese ballast. To find ballasts, start with what bulbs will fit in the fixture (all the better if you have a bulb already). Then search for ballasts meant to drive that bulb (which also fit in your fixture)
This symptom is impossible without silicon electronics being involved in the delivery of power. Passive wires and windings are not capable of causing this. Common problems are common, and my first take is usually correct - a series connected old-styl
Some are. You can also get transformers designed to mount into a 1/2” knockout in a junction box. The transformer proper sits outside the box
Some LED's just won't dim, or dim well. If it didn't say dimmable on the package, it probably isn't. G9's are typically 120v, so they shouldn't need a driver unless you bought something that is low voltage (12 or 24v)
I've recently installed smart (ZigBee) LED bulbs in my kitchen. These lights are on a dimmer switch, and even when I have the dimmer all the way up, the bulbs flicker when their internal dimming is set to anything other than 100% brightness. I was to
I don't know if it's really useful to compare a 120V LED bulb to the stuff you can cobble together from radio shack. First of all the commercial bulbs include a significant amount of circuitry to adjust the voltage, compensate for dimmers, etc. Most

I originally posted this in the LED forum, but perhaps this is better suited here as I am asking about handling current and not overloading a power supply. I posted previously (in the LED forum) about driving LED strips (5050 60 led/ M) from an Ardui
