Can tinted films make cheap lights visually pleasing?

    I believe that you are trying to shift   the color spectrum for your 
favor, however I think that would require energy, the laws of physics would 
dictate that without any energy change taking place, there could not be 
different wavelengths? This based on the idea that all chemicals give out a 
spectral signal, and that there is no way to make one chemical shine in a 
different specturm, you can block out certain frequencies, however the bulb's 
phosphors would have to make different leaps to higher frequency (similar to 
how water will evaporate, i.e. the highest energy particles move into the 
air, and only the lesser energy molecules are left in the dish, hence making 
the water cooler, i.e. evaporation). In this sense though, energy is going 
the other way, into the phosphors, making them leap to a higher quantum 
state, and eventually fall back down (that is what light is, the energy given 
off from electrons jumping to the next rings of the moleclue) Chemistry 
people? Am I far off base?  I know chemistry always brings out the flames, so 
lemme just say I'm trying to throw stuff out for discussion. I guess Ivo is 
the groups authority on lighting as I've seen, Ivo, any comments? Thanks, Bill
