My transformer is 150 watts; what is the wattage of these?
1885370
Wattage is 20 watts at 120 volts d.c. By my calculations 20 watts divided by 10 lights (leaves 2 watts per lamp). You can connect more than 10 (or less than 10) to match any size transformer that is 12 volts d.c. output. Make sure your polarity is correct with LED lights or they won't work. For a 150 watt transformer you could operate around 75 lights in series. For 5 lights you would need a 10 watt, 12 volt transformer. The 150 watt transformer should work any number of lights under 75, as long as you have 12vdc output.

This unit I purchased is the US distributed version which is 120 volts at 150 watts.

Wattage should be negligible. At .1 amp input and .3 amp output, I doubt this is going to challenge even the smallest of transformers.

andrew,just look for suitable electrical transformer with 100 watts and 6o hz

The output listed on the transformer/ballast is 20-40 watts. UV bulbs are not rated as much by wattage, but rather by their output/sterilization abilities.

I haven't measured the actual power, but the add says 15A. If you use a transformer from 220 that would be 7.5A, plus whatever winding loss you have. Or, approximately 1650 W, either way.

.55 amps (not .625)- Info from the spec sheet included with the transformer. Cheers -

These are 12VDC and draw about 0.25A at full brightness. A 30W transformer should be sufficient.

It depends on how many lights you have on the transformer already. The lights all together will only use 80 watts. 10 watts each. If you dont have any other lights on the transformer you have plenty of power! The light is bright but seeing that the lens is convex the light is diffused and doesnt resemble the light from the 20 watt halogen.

The 1863watt appliance is under 2000watt. But that's under normal operation. Instant wattage could be much higher especially when turning on the appliance. It is recommended to have the transformer at least 50% higher than the wattage of the normal operation load. So you should have at least 2500watt transformer. Or 3000watt one to be safe.

These are 12 volt not 120 volt! With that said you could use a 12 volt DC transformer or a 12 volt battery

IF they are 12V 4 watt? Then Yes, just remember to add up all the watts (each lights wattage) and be sure the total does not exceed the transformer wattage.

No transformer, just straight 110 feed to the fixtures. I've had them up for a while now, and no issues, though they do get very warm/hot when on.

the above numbers you have are the same as those on my transformer. Hope this helps you.

They are dimmable, but they run at 12 volts. If your transformer is a 12 volt unit designed for MR16 lights, then it will work.

Put an ammeter on it, I bet you have it overloaded. You may think you have 100w load, but if you have a short anywhere in the distribution, you will overload the transformer. Do not use it until you sort this out.

Yes 11w are fine. Multiply wattage by number of lights to determine if transformer has enough power. In this case, the 120 watt transformer will support 10 11w bulbs (10*11=110 watts).
