Introduction
Howard Lighting Products delivers exceptional value in our decorative, outdoor, commercial grade
luminaires and poles. Providing energy efficient light sources and excellent service has been a
hallmark of the company since inception.
Now we bring you the next generation in energy efficiency, value and service, with the introduction of
our sustainable LED solutions.
This solid state lighting system delivers extremely long life, high quality light, energy savings and
reduced maintenance costs as well as several other benefits compared to current HID systems.
This simple system, easily installed, has been designed to deliver maximum performance in a large
number of Howard luminaires for both new products as well as a retrofit in an existing fixture.
Quality of Light
High Brightness LED’s provide excellent color rendering (83+ CRI) which make people and
objects appear more natural.
A bright white, 3500k color temperature helps create a more comfortable outdoor setting than
typical HID systems.
LED systems achieve full brightness (no warm up time like HID) immediately after being powered on.
Instant restart after a power outage, eliminates the long wait typical of HID lamps needing to cool
down before restarting.

Making the change
Green Technology
No Mercury or other hazardous materials are used in the
manufacturing of our LED system making it environmentally safe
and recyclable.
LED technology performs comparably to HID sources using less
power therefore reducing CO˝ emissions.
Energy Savings
Higher sustained efficacy (lumens per watt)
Lower driver (ballast) power consumption.
Depending on the fixture and system, an LED light source can
reduce energy consumption by 30% to 50% while delivering equal or
greater lumens to the target area.
Reduced Maintenance
LED systems are designed to last for more than 50,000 hours at
70% initial lumens.
No costly lamp replacements during the design life of the product.

Change
The chart illustrates how lumen depreciation and life affect the total cost of
the lighting system. HID sources lose light output quickly during their rated
life compared to LED. During the 50,000+ hour design life of the LED,
there will be 3 or more lamp changes for the HID.

When using non-refractive fixtures, the tilted LED unit is designed to
be used for both Type III and Type V distributions. The unit will open
up after it clears the neck of the diffuser and the individual panels will
be positioned at the optimal angle to increase downward efficiency
and reduce wasted up light.

For refractive lens fixtures, the vertical unit is specified to maximize the
output of the optically designed lens. The position of the LED boards on
the heat sink has been carefully calculated relative to the geometry of the
cut prisms to ensure that the light distribution is uniform and maximum
spacing between poles is achieved.
