A similar question came in recently. Here's the posting Re: Question?

Most of the web sites I looked at said it was 3.83 to 4 x 10^26. You might
find the following web sites interesting:

Dear Sir,
Do you know what the power of the surface of the sun is in watts/m^2? I
took the power at the earths atmosphere of 1350 W/m^2 and multiplied by
R^2 where R is the distance of the Earth to the Sun for increase in
intensity. The result seemed very high of 3 x 10^25 W/m^2. With a
average photon energy of blue light I calculated meters/photon. The
spacing was 10^-22 meters, I thought it should be about 10^-14 meters.
Thank you for your help.
