Yes, the base type is the important part. Go to www.donsbulbs.com to determine exactly what type base your bulbs are. My fixtures were mostly the 1141 bulds, which use the BA15s base. Some of the LED panels I bought included BA15s adapters, others didn't. For those that didn't, I broke the glass out of the 1141 bulbs and soldered the wires form one of the un-used adapters into the bulb's base, then filled the base with silicone. It was actually pretty easy if you can solder at all. Another option would be to simply hardwire them into the fixture.
