How many amps does a single light fixture (single light bulb) draw?
831914
Since Watts = Amps x Volts, a single 20 watt bulb on a 12 volt circuit would draw 1.66666 amps. (Amps = watts/volts = 20/12 = 1.66666)

ROC 1 ANSWERED YOUR QUESTION BUT NOT SURE WHY YOU WERE ASKING IT??? these lights function off of a LOW VOLTAGE 12V TRANSFORMER putting out 60 watts matched to power the three 3 - 20 watt xenon bulbs in the hockey pucks.... no additional lights can be powered by this transformer with 20 watt xenon bulbs in them... On the amperage question each transformer only draws about .5 amps (ROC1'S ANSWER 1.6666 X 3 = 4.99998) so no problem installing a lot of 3 light kits on one 15 amp circuit..

This is a more complex problem than it would seem. I tend to use overkill when sizing wire to a given load. In addition, a friend replaced all of my fixtures original quartz halogen bulbs with LED's that draw less current. And generally speaking, it is not just the load in amperes, but the length of the wire run in feet that determines the wire gauge needed. I would suggest that you employ someone with knowledge in electronics to size and determine your layout. This is especially true if your layout is complex and heavily loaded. I wish I could be of more help, but I have to hire an electrician. Good luck!

According to ge tech specks... The lights draw 1.8 amps on low beam and 3.6 amps on high beams.

I don't the answer but I can tell you it puts out more light than a 50 watt 12 volt bulb that draws 5 amps...hope this helps, buy the way the 3 I bought are still working in my engine room on my fish boat...

"Wattage" is normally shown as "Max" wattage when in operation. If this product is listed as .8 watts (120vac x .067ma) then the "idle" current should be significantly less, probably about .020 amps/20ma or 120*.02= 2.4 watts. It could easily be less, depending on the circuit design. When the lights are not on, the unit is 1)determining if it is light or dark (dusk to dawn sensing) and 2)if there is "motion" in the vicinity. The energy used during this "idle" process is extremely low.

I am not an electrician or EE, but I don't think the bulb can determine what voltage it will draw ----- that is determined by the system supplying the electricity to the bulb. If the system is putting out 12.0 volts, the bulb(s) see 12 volts. Or, 11.5, or 13.0 or whatever the voltage of the system may be. The bulb will not alter that voltage. The bulb CAN determine how much current it draws --- which would, in this case, I think, be rated in milliamps. There may be a way to measure resistance across the terminals of the bulb and calculate the amperage it will draw at a specified voltage --- again, I must defer to a qualified electrician.

I don't recall a limit stated on the adapter itself. But most candelabra bulbs are low wattage - maybe 40 watts max - and there will be a wattage limit written inside the light fixture itself. The light fixture wattage limit is for avoiding heat buildup in the fixture. I used CFLs and put in either 60 watt equivalent or 75 watt equivalent CFLs, which I think are 13-18 watts of actual power consumption. So much less heat than the specification in the fixture.

I believe 200. We put 4 of these on the sign at the entrance of our subdivision, powered by solar charged battery system. They draw only .25 amps each at 12 vdc and fully illuminate our sign

5w 13 light's = 65 watts 110v .6 amps would be how much 13 light's would pull on a single circuit

I don't know what kind of light you have in mind, but the typical household light switch for lighting circuits is rated at equal, if not less amps, usually 15-20 amps. Unless you are using it for some higher output lamp, it should work fine. Remember, watts divided by volts equals amps. For instance, if you are operating a 75 watt bulb under a 120 volt circuit, you would determine the amps as 75/120 = .625 amps. If you are operating more than one bulb, be sure to add up all of the bulb wattages before you do the math. This switch is rated at 20 amps, so don't go over the rated amperage. The screw portion of the switch is right at 7/16 in. Be careful and good luck.

The 10 ft. Section is 1 amp. I tied mine into a single light fixture in my basement and it worked great. I wouldn't recommend laying tile without one of these under it.

it is just a switch. As long as you are not going over 15 amps, it will work with anything. If you are turning on something over 15 amps. the you will need a heaver duty switch that is made for higher amperage. In a household environment, a single light is rarely over 15 amps. You can tell by the size of the wire on the light. if it is 14 gauge, it is 15 amps. If it is 12 gauge or larger, then you will need a heavy duty switch.

This bulb has a single contact on the bottom for + and the side connects to the -. It also draws 1.44 watts so around .11 amps. It is a 12 volt bulb also. I surmise that it should work, but I cannot find the specs on your particular bulb.

Update on my previous answer since I now have a new meter to measure all DC current draw on my vessel. With all 5 lights on, they draw 1.1 amps of DC power...That is a very low current draw!! I am adding 2 more this winter.

1 in a package. They draw .05 amps compared with 1 amp for the original bulb

It all depends on how many amps the light strip draws. 1 amp would drain it in 12 hours, but you don't want to deplete it totally if you want it to last. I use mine as an emergency power supply for emergency radio equipment.

The model #980A draws about 38 Watts or .31 Amps (1/3 of one ampere) or less than a 40W light bulb. The model #980A requires very little power and is very cost effective for its intended uses.
