The change in energy would be negative because it is going from a higher energy state to a lower energy state. It is important to remember that only the change in energy can be negative, not energy itself.
The energy in a hydrogen atom depends on the energy of the electron. When you move from a higher state to a lower state, it decreases energy and the atom emits photons. The photon energy will always be positive.
When atoms are going from a higher energy level to a lower energy level you would use the equation E(photon)=-deltaE, which always makes energy of the photon positive. When you have a negative change in energy it means light is emitted and the energy of the light emitted is always a positive number.
