Replacement or New Construction; A Solution for Every Need
LED provides a superior alternative to traditional sources for replacement of existing fixtures or for new construction.
• Over 5x longer life; virtually maintenance free.
• 70-90% reduction in energy consumption.
• Superior lumen maintenance over life.
• Clean white light for improved aesthetic
and visibility.
• Superior luminous uniformity and glare control.
• Qualifies for many available utility rebate programs.
• Contains no mercury.

This Application Guide includes a reference to determine the appropriate Everline WPL13 model to replace an existing metal halide, high pressure sodium, or
compact fluorescent wall pack or to determine the mounting height and spacing range for new construction applications.
The following pages also illustrate the annual savings that can result from replacement of existing, non-LED wall packs with the WPL13. Additional savings
opportunities exist in regions with higher electric rates and rebate programs.

Explaining Equivalence
70 W Metal Halide Wall Pack
≈15 ft
≈1.5 Mt. Ht.
“How can an LED wall pack delivering 904 lumens be considered equivalent to an HID wall pack using
a 5,000 lumen 70-watt metal halide lamp?”
Let’s use the 70W metal halide wall pack as an example.
≈15 ft
≈1.5 Mt. Ht.
This guide illustrates LED / HID equivalence in application using lighting calculations to compare the
WPL13 to representative non-LED wall packs. This “real world” approach considers all factors
including light losses, optical efficiency, and optical directionality.

Light Loss Factor: A 70W coated metal halide lamp produces 5,000 lm initially and mean lumens
over life of around 2,800 lm. Although that’s a 0.53 Light Loss Factor (LLF), most engineers use
around a 0.72 LLF for HID. We now have only 3,600 lm from the metal halide lamp (5,000 x .72). A
LLF of 0.9 is commonly used for LED due to its superior lumen maintenance and longer life.
More light directed toward wall
(mostly absorbed)
PLAN VIEW: Isofootcandle line
Optical Directionality: Not every lumen exiting the fixture beneficially contributes footcandles to the
task (the ground in this case). HID and CFL lamps are difficult to control with precision. Lumens
directed to the wall are mostly absorbed. Lumens directed at high angles are wasted as stray light or
uplight. Excessive lumens directly below wastefully produce a non-uniform hot spot. Fortunately, LED
sources are much easier to control, allowing more effective use of fewer lumens.
That’s why this Application Guide is based on actual lighting calculations.
Outdoor lighting requirements commonly call for a minimum illuminance of 0.5 fc. The diagrams to the
right illustrate the calculated ground illuminance pattern of the a typical 70W metal halide cutoff wall
pack and the WPL13-10L, both at a 10’ mounting height. In both cases, the 0.5 fc line is about 1.5
mounting heights in front and to each side of the fixture, resulting in the same fixture count and
spacing.

Light Loss Factor: 0.72

Optical Efficiency: The 3,600 metal halide lamp lumens also suffer fixture optical losses. The 70W
metal halide fixture depicted in the guide is pretty typical at a 68% optical efficiency. So, we now have
only about 2,450 lm exiting the 70W metal halide fixture vs. 904 lm existing the WPL13-10L.

PLAN VIEW: Isofootcandle line
Hence, both fixtures are equivalent from the most “real world” way of looking at things… application.
