to accommodate the fixture’s dimensions.
Depending on the lamp intensity and the focal
length, one to four fixtures can be mounted on a
cross-arm or bullhorn. There are also directional
bullhorn mounts which can achieve a 360-degree
illumination pattern. Composite poles can be
configured with a single “cap” mount at the top
that can receive a bullhorn or “T-Bar” – not to be
confused with a T-bar lift. Using a T at the top ac-commodates
U-bracket mountings.
Keep in mind that bullhorn mounts can be
attached to most chairlift towers, eliminating
independent light poles for some areas. When
mounting lights to towers, make sure the fixtures
are capable of handling vibration. Bulbs that have
filaments can be damaged by excessive shaking or
vibration. Mounting hardware is also susceptible
to metal fatigue if there is too much vibration.
In most cases, it is unlikely a snow sports venue
will require the design solution for Hurricane Ma-ria.
However, it is helpful to know that composite
utility poles offer a high-integrity, cost-effective
alternative to wood and metal. If new lighting
infrastructure is in upcoming plans, composite
poles may be the ultimate way to go.
Composite poles are extremely rugged with
low lifetime maintenance costs, ideal for
locations with harsh or extreme weather
