Check your manual, mine has a list of bulbs. Then search for an LED alternative.
If you have the flourescent tube type you can convert these by using LED ribbon. I did all of mine for ~$100. I added 3 strips, the two outer ones connected through the original switch in the light fixture, the third one I added a second switch. Now I can have 1, 2, 3, or 0 lights on in each fixture so I can adjust the amount of light I want. At night I can get by with 1 row lite if I'm just watching TV. Turn on more while cooking etc.
