Usually lamps have a maximum wattage, which tells the highest wattage light bulb that can be safely used. Any light bulb of a wattage lower than the maximum will use less energy, and so will be safe to use in the lamp. If you have a lamp with a maximum of 150 watts, you can lose all of the lower wattage light bulbs in that lamp.
Good luck with your project!
