High Mount Brake Light Question

Hey guys, quick question. My third brake light went out behind the rear windshield. I couldn't find a number on it like 1156 etc. It just has a P21W on it. So I took that to AutoZone to get a replacement bulb and couldn't find any replacement light that looked correct. Even the one they pulled up on the computer didn't match the factory bulb. So the employee found me an 1156 bulb that does fit but it says it is 26.9W whereas the factory bulb is 21W. Is this OK? I don't want to cause any electrical problems in the vehicle. I did happen to find a bulb Googling around that is a 7506 but no store really seems to carry that one. So the question is, am I ok using a 26.9W 1156 bulb as opposed to a 21W bulb that was factory installed? Thanks everyone.
