Lights

Hi everyone,
I want to add some nighttime lighting to my scenes and I followed the tutorial on the website, but I still have some problems.
I made a small 2'' x 2'' square on the ceiling as you can see in the first image. I then created a new material and applied the "100W incandescent" material to it (colored in yellow).
I rendered the scene with the Reinhard and obtained the second image.
Then, I rendered the scene with the Reinhard method again but I set the power of the light to 25W instead of 100W (third image). As you can see, both images are nearly identical, even if the light has a different power. Why?
I then redid the renders but this time with the Camera method. The fourth image is with a 100W light the fifth one is with a 25W light. There's a small difference, but they are very dark compared to the others.
Is there a way to set the lights correctly and obtain a clear image like the ones rendered with the Reinhard method?
