Detecting GFP colonies

I have tried GFP under the TDH promoter and got very bright fluorescence in
colonies.  This is a strong promoter, so this may be the explanation.  Also,
remember that you have to use long wave UV so a transilluminator is not 
optimal (I forget the best excitation wavelength but it is closer to blue 
than to UV.)
