Well, I know I can buy bulbs that will screw into the lamp; I just don’t want to kill the lamp.
you are right to fear what goes into the lamp. LED’s typically require less than 10% of the wattage for a comparable lumen output from an incandescent lamp. This would not be a problem except that it is possible that the wiring and any electronic controls may not be able to keep from burning out using 1000% more power than it was designed for. There is a huge selection of LED lamps to choose from, you should look on line and get what you need and stay within specs of the fixture.
