Choice of Luminaires
Unless it is essential to have light aimed above
the horizontal (as for building facades, landscapes, and central
business districts, for example), luminaires with minimal uplight
should be used for lighting projects.
When emitting light above the horizontal is absolutely necessary
and in accordance with Texas Health and Safety Code,
(see appendix), the designer should strive to keep the
above-horizontal light as low as practical to accomplish the intended
effect. This can be achieved by using lower wattage luminaires,
by shielding, or by luminaire design.
