If they do not have a ballast, then yes. If you can see the wiring look for components other that resistors. If you see caps, chips, inductors, or diodes you cannot dim it. I cannot offer more without more details on the lamp. Consult the packaging.
No, a single pole switch is not designed to function as a dimmer. Dimmer switches are specifically designed to control the amount of electrical current flowing to a light fixture, allowing for adjustable brightness levels. Using a single pole switch as a dimmer may cause damage to the switch, light fixture, or both.
No, the dimmer switch needs its own individual circuit power supply to feed the fixtures connected to it. The black of the second dimmer switch can not be connected to the red wire of the first dimmer switch. Now if you are talking about using a common "hot" to feed two dimmer switches then this can be done. The neutrals will be common also. So what you should have is two black wires connected together with the incoming "hot". Two neutrals connected together with the incoming white. The red from each dimmer is then connected to its own individual fixture load.
A dimmer reduces the voltage supplied to a light fixture, which in turn decreases the intensity of the light. It does not directly reduce the amperage, but the decrease in voltage will result in a lower current flowing through the circuit.
A rheostat is an extremely ancient form of variable resistor that was used very largely to vary voltage. As you mention replacing a light switch, presumably you want to install a dimmer? If so, lighting dimmers are solid state and are a simple replacement for a standard switch. NOTE - you cannot use a conventional dimmer on anything but standard incandescent lamps. They will not work on low volt, fluorescent or halogen lamps (or HID). Make sure that the circuit breaker is turned off before starting work on changing the switch out. Just for the sake of convention the top wire on your conventional switch should be the hot one. Connect this same wire to the top wire that is on your new dimmer switch. Make sure that the dimmer switch is in the off position before turning the breaker back on.
No, not directly. You can buy Halogen bulbs that are made to be used in a standard light socket. They are for sale at the standard outlets. I have a number of these in my house, and I use these in some of my light sockets. Just for you information I have one in my lap as I am typing this it is a Philips Master 120 Volts 60 Watt bulb. The only condition is that you have to get a specific bulb for dimmer circuits, a standard halogen does not work with dimmers. The bulbs have ceramic insulator protecting a balast circuit, the dimmer bulbs have a rather large ceramic end, that is sometimes enclosed inside the standard light globe. All the standard bulb manufacturers should sell these. You just cannot use Halogen bulbs in enclosed lights unless they are made for this purpose, as is the dimmer variant I wrote about.
To replace a standard light switch with a dimmer switch, first turn off the power to the switch at the circuit breaker. Remove the cover plate and unscrew the switch from the wall. Disconnect the wires from the old switch and connect them to the dimmer switch according to the manufacturer's instructions. Screw the dimmer switch into place, replace the cover plate, and turn the power back on to test the dimmer switch.
something in a circuit
I'm not sure what you mean by turning a dimmer switch "up".-- When the dimming action of the device is turned 'up', the bulbbecomes more dim, that is, less bright.-- The dimmer may have an arrow printed on its control, labeled 'brighter'.In that case, when you turn the control in the direction of the arrow,the light becomes brighter, i.e. less dim.
No it's series circuit.
To wire a dimmer switch correctly, first turn off the power to the circuit. Remove the old switch and connect the dimmer's wires to the corresponding wires in the wall box. Follow the dimmer switch's instructions for specific wiring details. Secure the dimmer switch in place and restore power to the circuit to test the dimmer's functionality.
Yes, you can install a dimmer switch on a 3-way lighting circuit by replacing one of the existing switches with a compatible dimmer switch designed for 3-way circuits.
To wire a dimmer switch, first turn off the power to the circuit. Remove the existing switch and disconnect the wires. Connect the dimmer switch wires to the corresponding wires in the wall box, following the manufacturer's instructions. Secure the dimmer switch in place and restore power to the circuit to test the dimmer switch.
That is the dash light dimmer control switch.. Rheostat = Dimmer. Bright to dim.
To properly install a dimmer switch in your home, first turn off the power to the circuit at the breaker box. Remove the existing switch and disconnect the wires. Connect the wires to the new dimmer switch according to the manufacturer's instructions. Secure the dimmer switch in place and restore power to the circuit. Test the dimmer switch to ensure it is working properly.
Do nothing. But in a parallel circuit, all the bulbs will get dimmer.
To install a dimmer in place of a light switch, first turn off the power to the switch at the circuit breaker. Remove the existing switch and disconnect the wires.
