If you get a moderately powerful >300W xenon arc lamp and build a parabolic reflector, you could just shine it at the tree. Probably more expensive and a bit more dangerous due to the tremendous heat generated.

Some arc lamps like this lamp have a reflector built in. The two types used are parabolic and elliptical. You could collimate the elliptical to get the beam you want.

There are a lot of spectrum grow lamps as well that you could look into.
