The light spot on the black background was made with the GRADIENT TOOL directly on the background layer, using the radial gradient from gray to transparant.
The shadows behind the text was made with the layerstyle tool that you will find at the bottom of the layers tab (see the picture in my previous reply).
The light effect on the text was made by adding a mask to the text layer (see the picture in the previous reply. You find the ADD MASK button also at the bottom of the layers tab. Then by applying a linear black to white gradient to the mask (make sure you select the mask first!), the light effect can be simulated. Just play with the place, direction and the length of the gradient and see that you can make it exactly as you like.
