Eau de toilette vs. cologne

[VinceFX]

Can somebody tell me difference between an eau de toilette and a true cologne? There must be some difference because the trumpers catalogue seems to reference them individually in some instances but I just don't see the difference.

Any info is greatly appreciated.

Thanks,
Vince
