Questions about: lighting - страница 7

I use separate detectors from lamps, and here's how I wire them. First, I use the type of sensor which has its own neutral (rather than the type which has no neutral and sits in a "switch loop". ) This is very important
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
Just looking the fixture itself, and giving the probability of other points of failure. .
I have a suspended ceiling in my bathroom with 6 halogen (MR160 12V 35W) spotlights, each light has its own transformer, which I believe is to covert the voltage from 240v to 12v. Some of the fitting do not work entirely (I have checked by moving the
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)
It sounds as if the light is being controlled by a single 3-way switch. The hot lead is run to the common and two switched hots are run to the traveller terminals. You could create a master switch by adding a single pole switch that interrupts the ho
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
Advancements in technology have made it easier to collect data in the home, in warehouses and on production floors, and across cities. As this data is collected and interpreted, decision makers can now make meaningful use of it. These strides are cre
Usually the two wires that go to the wall switch are used to break the load, (switch the power (COMMON) OFF and ON to the fan). The other wires in the ceiling box are the supply wires. You need to look at the wires and find the pair that are LIVE, th
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
