There are special contactor that are made to switch lighting loads. These relays and not wattage rated but amperage rated. Use the following formula with the voltage that you are going to use to find the size of contactor that you need. I = W/E, Amps = Watts/Volts.
It depends on the voltage and whether the lamps are actually 40 watts or 40 watt equivalent. Watts / volts = amps
Depends if ballast is in fixture and switch is on. Several watts if new ballast and perhaps 15 watts for old ballasts....
the most economical is the incandescent bulb because the power of bulb is low only while the fluorescent lamp is low and additional the power of ballast from 10%-20% power consumed.but the fluorescent lamp is 5 times brightly the incandescent bulb.
Watts are calculated by multiplying the voltage by the amperage. To calculate the wattage you need both these numbers
The typical wattage for closet lights depends on the person. Some want their closet lights to not be very bright, so they will choose something that has 20-30 watts. Some other people prefer something a little brighter, so they will choose 50 watts.
Electric lights that use from 0.02 watts to 50,000 watts have been manufactured. The CFLs, fluorescent tubes, and incandescent bulbs in your house probably operate in the range of 20-100 watts.
It depends on the voltage and whether the lamps are actually 40 watts or 40 watt equivalent. Watts / volts = amps
Lamps with five flexable lights that provide great lighting and come with shades and four way switches. The information below is telling you how brite the light will be if you used the same number watts in the lamp. Using 15 watt bulbs Using 30 watt bulbs Using 40 watt bulbs Using 60 watt bulb Switch 1: 30 watts Switch 1: 60 watts Switch 1: 80 watts Switch 1: 120 watts Switch 2: 45 watts Switch 2: 90 watts Switch 2: 120 watts Switch 2: 180 watts Switch 3: 75 watts Switch 3: 150 watts Switch 3: 200 watts Switch 3: 300 watts Switch 4: 0 watts Switch 4: 0 watts Switch 4: 0 watts Switch 4: 0 watts
Remember that dimmers are for incandescent lights only unless you invest BIG BUCKS on dimmable fluorescent lights and fluorescent dimmers. Make sure that the switch that you replace with the dimmer does not control a plug-in outlet unless it is a lamp. You could do harm to an appliance not designed for such use. Otherwise,just add up the wattage of all the bulbs on the dimmer and buy one of the next size rating. So if you have two 60 watt bulbs, two 75 watt bulbs-- that's 270 watts total.Find a dimmer rated for 300 watts or more.
3 watts to 125 watts.
If it is a 120volt light, then it is watts / volts. 32 watts / 120 = .2667 amps. <<>> fluorescent lights usually have a power factor around 0.6 so a 32 watt bulb would take around 32/(120 x 0.6) amps or 0.44 amps.
Watts are a unit of power. So 40 watts of power to an LED are the same as 40 watts of power to a fluorescent. Sometimes LEDs are rated in equivalent watts which is an attempt to relate watts to brightness or lumens. You need to compare lumens and the "temperature" of the bulbs in Kelvin to get the comparison I think you are looking for.
Depends if ballast is in fixture and switch is on. Several watts if new ballast and perhaps 15 watts for old ballasts....
When using lighting for making films there are two types of lighting that can be used, hot lights and cool lights. Hot Lights are named such because they run at 500-800 watts and are hot. The down side to using these is they can be a fire hazard. However, they are a great source for continuous light. Cool lights are fluorescent and don't get hot. They provide a more natural day light appearance. The run at a much lower wattage.
That depends on two things: 1. the capacity of the relay that is inside the timer. 2. the current use (watts) of the lights that you are using.
A 55 watt fluorescent light only pulls 0.4 amps. Lights can be installed on a 15 amp breaker using 14/2 wire. A maximum of 1440 watts is all that is allowed on a 15 amp circuit.
the unit which are measured for power of lights are watts....
