Since the wavelength of the light is 1850 nm, you can find energy per photon by using the equations E=hv and c=vλ to get the equation E=hc/λ. Plug in the wavelength, constants, and solve to get energy per photon. Since the answer is energy per photon and the bulb emits 11J of energy, divide 11J by # of J/photon in order to get the number of photons generated and emitted.
