primarily direct illumination is preferred.

effect and conceals the lamp at all viewing angles.
Highly-reflective textured matte white paint for increased
efficiency.
Die-cast aluminum end caps secure the shielding and
provide a high-end look.
Optional decorative brackets add a distinct touch to
the environment.
Shielding/electrical module hinges onto trunk and
snaps securely into place.
Entire system can be installed without the use of tools.
All parts painted after fabrication to facilitate installation,
increase efficiency, and inhibit corrosion.
