Product versatility is all about the right product for the application. LLT offers up to four lumen packages with appropriate output ranges
for general ambient lighting in many types of architectural conditions. Lower lumen packages may be applied to low ceilings, corridors or
low ambient light locations. Medium and high lumen packages trend towards standard general lighting. Very high lumen packages may be
selected for high ceilings, high light level needs, retail or health care.

ENERGY CODE COMPLIANCE
CONTROLS INTEGRATION
LIGHTING EFFICACY
As of October, 2013, each state must adopt, at minimum, the national energy code ASHRAE 90.1-2010. The code is aimed
squarely at energy reduction and has a direct impact on lighting. States may choose to exceed the national requirement.
Saving energy through lighting control is a primary strategy for lighting design and code compliance.
LLT is compatible with a full range of controls including, but not limited to:
(LUMENS PER WATT)
Among other things, ASHRAE 90.1-2010 will reduce the amount of power that commercial installations can use for
lighting; that is the watts per square foot, or Lighting Power Density, is reduced compared to prior national standards.
It is also noteworthy that Daylight Harvesting requirements are expanded and applied to smaller spaces than prior versions
of the national code.
OCCUPANCY & VACANCY SENSORS
ASHRAE 90.1-2010 must be applied both to new construction as well as modifications or additions of 10% or more.
Therefore, the code will apply to a wide range of applications including retrofit.

ASHRAE 90.1-2010 POWER DENSITY HIGHLIGHTS
ASHRAE 90.1-2010 requires alterations of 10% or more of a space to
comply with LPD requirements.
Occupancy Sensors automate lights to turn both on and off.
Vacancy Sensors automate the lights off function only and
require a manual on function.
