About 150 watts.
The total wattage of the light fixture with 3 60-watt bulbs is 180 watts (3 bulbs x 60 watts per bulb).
If the exit fixture uses a LED lamp it will have a 1 to 3 watt rating. If it is a incandescent bulb, each lamp will draw about 25 watts each.
Yes, it is only pulling 18 watts.
The fixture manufacturer goes on the side of safety. A 75 watt bulb puts out both more light and heat than a 60 watt bulb. It can make the fixture burn out sooner. For even more light, why don't you go with a florescent and get a 27 watt bulb that gives off the same amount of light as a 100 watt bulb? That will give off far less heat and be far better for your fixture?
As long as the fixture in the confined space is approved for confined space and the wattage rating of the fixture is not below 60 watts then there should be no problem using a 60 watt bulb in this situation.
The recommended wattage for 25 watt light bulbs in this fixture is 25 watts.
The recommended wattage for a 150 watt light bulb in this fixture is 150 watts.
The total wattage of the light fixture with 3 60-watt bulbs is 180 watts (3 bulbs x 60 watts per bulb).
Under two conditions it can. One the fixture that the lamp goes into has to be rated at 250 watts. This is highly unlikely in a home lighting fixture. The other is that the lamp has to be an incandescent lamp.
The recommended wattage for a 25-watt light bulb in this fixture is 25 watts.
Look at the wattage capacity of the fixture. Some fixtures are limited to 65 watts, some can take much more. If you use a larger bulb than what the fixture was designed for you create a fire risk. If you need to use a larger bulb but the fixture is limited to 65 watts, you need to change the fixture.
If the exit fixture uses a LED lamp it will have a 1 to 3 watt rating. If it is a incandescent bulb, each lamp will draw about 25 watts each.
There are 1000 milli-watts in one watt.

1 mega watt is 1,000,000 watts
