I've been trying to get a material to glow without effecting its surroundings
with a 'blinding' light, but in order to get the glowing part of the scene to
look how I want it to, the rest of the scene is illuminated far too greatly.
In the scene below, I would like some reflection of the light in the water, but
it's a bit overpowering as it is now, and the ramp beneath the light is also
illuminated much more brightly than desired.

Any suggestions on maintaining a similar look for the light fixture while
diminishing its effect on the surrounding scene would be appreciated.
