Thank you, DR ArnoldBrockman! I finally bit the bullet and dragged out the big ladder. That was an ordeal unto itself, but the bulb is now replaced and the ladder back in place. I've been recuperating for the past hour. The first time I tried it, about two hours, I pulled something in my left leg and as soon as I got off the smaller ladder, I fell straight to the floor. I'm glad I didn't fall off the ladder; that might have been dangerous.
