When measured with an infrared thermometer it read 169.9 degrees F.
90 degrees
It depends on the bulb
Yes.
1 Joule = 1 Watt.sec, ie 1 Watt for 1 second. A 75 Watt bulb dissipates 75 Joules every second, so the answer is 10/75 of a second = 0.1333 seconds
It is equivalent to a 75 watt incandescent bulb
The bulb's power, 75 watts, is the power it uses continuously all the time it is switched on. The energy it uses can be measured in watt-seconds (Joules) or in watt-hours. A 75 watt bulb uses 75 watt-hours each hour, which is 0.075 kilowatt-hour.

A 75 bulb will use more electricity.

A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.

Usually the 60-watt limit is used to prevent the lampshade overheating, so a 75-watt bulb should not be used. But if more brightness is required, try a low-energy bulb because a 15-watt one gives the same light as a 75-watt incandescent (old-style) bulb. Or a 20-watt would be even brighter.
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.
25 watts?
