CONTRACTOR SELECT ESX1 SERIES LED
INTENDED USE:
The ESX offers a complete area lighting package providing everything needed to replace
150W to 400W HID area luminaires. Adjustable light output provides two light levels from
one product, allowing greater exibility while helping reduce inventory costs.
CONSTRUCTION:
The ESX LED area luminaire features a rugged die-cast aluminum main body housing that
uses heat-dissipating ns and ow-through venting to provide optimal thermal management
that both enhances LED efcacy and extends component life. The mounting arm is made of
extruded aluminum and its reversible function allows for mounting on round and square
poles. The luminaires optics are IP66 rated, and sealed against moisture and environmental
contaminants. The low-prole design results in a low EPA. ESX is rated for minimum 1.5 G
vibration load per ANSI C136.31.
ELECTRICAL:
Light engines consist of high-efcacy LEDs with LED lumen maintenance greater than
L87/60,000 hours. Color temperature (CCT) options of 4000K and 5000K with minimum CRI
of 70 are available. Electronic drivers are 0-10V, capable of continuous dimming, and ensure
system power factor >90% and THD <20%. All luminaires have 6kV surge protection. Driver
input voltages available in MVOLT (120-277V) and HVOLT (347-480V).
INSTALLATION:
ESX features an extruded aluminum arm that is reversible allowing it to mount on both round
and square poles. ESX1 can be mounted onto minimum 3.5" square and round poles. An
accessory wall mount bracket is also available.
LISTINGS:
UL listed to meet U.S. and Canadian standards. Suitable for wet locations. Rated for -40°C
minimum ambient.

UPA – REVERSIBLE ARM MOUNT:
The UPA reversible arm is designed to mount onto round and square poles. During
installation, the at end of the arm is placed against the at surface on square poles. When
using with round poles, the arm can be turned around so that the curved end is placed
against the curvature on round poles. ESX1 can be mounted onto minimum 3.5" square and
round poles.
