OUTDOOR LIGHTING APPLICATION:
- Street lighting
- Roadway lighting
- Parks and Community
Facilities
- Parking lots
- City Landscaping
- Residential and
Commercial Buildings
- Pedestrian and
Bicycling Pathways
SLIDE 5
PURPOSE OF OUTDOOR LIGHTING:
- Provide a safe and secure
environment at night.
- Extend the use of parks and
walkways into the night.
- To enhance historic/notable
features
- To enhance travel on the roads
and at intersections.

Uncovered parking lots and drives 1.6 W/m² Walkways less than 3 meters wide 3.3 W/linear meter Walkways 3 meters wide or greater 2.2 W/m² Outdoor Stairways 10.8 W/m² Main entries 98 W/linear meter of door width Other doors 66 W/linear meter of door width Open sales areas (including vehicle sales lots) 5.4 W/m² Building Facades
- 2.2 W/m² for each illuminated wall or surface
(or)
- 16.4 W/linear meter for each illuminated wall or surface
length
Entrances and gatehouse inspection stations at guarded facilities 13.5 W/m² Drive-up windows at fast food restaurants 400 W per drive-through
Lighting Power Densities for exterior areas not listed in Table 502.05 (1) should be no greater than those values given in ASHRAE 90.1-2007 Table 9.4.5or equivalent as approved by DEWA.

Guidelines for Specifying LED Lighting Solution for Projects :
- A LED luminaire consists of the following:
- LED modules, ballast or driver where applicable,
- Heat-sink for thermal management,
- Fixture and optics assembly
- LED lighting type should be identified in the projects.
- Self-ballasted type. (direct connection to supply mains)
- Non-self-ballasted (required separate driver for supply mains connection)
- LED
modules replacement/upgrading possibility within the luminaire without replacing the whole luminaire/fixture.
- Adequate ingress protection (IP) rating of the LED luminaire should be prescribed
for the intended application under specific environmental conditions. (IEC 60529)
- Optics (lens, diffuser or reflector) considering that Well-designed optics will reduce
- ptical losses and help improve the luminaire efficacy.
- Type of driver to power and control LED lighting (IEC 62384)
SLIDE 9
- LED lighting should have well-designed thermal management provisions to ensure
LED junction temperature be maintained within design limit.
- Maximum allowable ambient temperature for the LED lighting should be considered,
so that it can operate without affecting its life or colour stability. (30-45 deg C)
- Life and lumen maintenance, change in light output of a light source over
- perational life, relative to initially measured light output
- L70 = time to 70% of original light output at XX% of operational hours
- L50 = time to 50% of original light output at XX% of operational hours
