Light block placement should be reversed

I really like the light block when building, especially how it's invisible so you don't have to see it. However, there is one problem that I have with the light block. Increasing the light level is a real pain on the finger after placed.

I think that instead of placing the light block and increasing the light level it should be the opposite. The light block should be at full light when placed and decrease as needed. This means that players could really light up places where they don't want mobs to spawn. It would also save everyone's fingers from overheating and blowing up :).

I hope you consider my suggestion.
