I own the adorama de-shadow box, which came with two lamps. One just dropped off the table and now doesn't work. Before I purchase an additional bulb, is there something else I should try first? I tried to remove the bulb, but can't. Is it a screw or push-type. I don't want it snapping off in my hand! Thank you for any guidance.- Julian
Actually, it is the push-in-and-turn type with two little lock terminals on the end. It is definitely not a screw in type with threads.
