Step 2: SSL Luminaire Testing
Independent testing laboratories
Uses absolute photometryrather than relative photometry (IES LM 79 08)photometry (IES LM-79-08) Must measure luminaire as a
complete system
Benchmark products for each application are also tested to LM-79

GATEWAY Demonstration Program
• Purpose: demonstrate new SSL products in real-world applications that save energy, match or improve illumination and are cost-illumination, and are costeffective
• Demos generate critical Central Park, NY Photo: Ryan Pylegfield experience providing:– Feedback to manufacturers– Data for utility incentivesy– Market readiness of specific
applications to users– Advancement in lighting

• Integral occupancy sensor dims fixture to 10% power
Before (HPS)
• 55% installed wattage reduction in high state; 95% reduction in low
• ~80% kWh energy savings• 80% kWh energy savings expected, incl. dimming
• Initial minimum horizontal illuminance increased 21%; average decreased 53%
• ~8 year simple payback (for
After (LED & Sensor)
• ~8 year simple payback (for retrofit), ~5 year for new
• 1:1 replacement

• Some sensor failures and tweaking needed
Nike and TJ Maxx parking lots
• LED full-cutoff luminaires, t l 30’ ltwo per pole, 30’ pole height, 110’ x 150’ spacing
• Shut down to low levelShut down to low level (35%) output when no cars or pedestrians detected
• PIR occupancy sensors mounted on each luminaire, “looking” downlooking down
• Occupancy sensors have detection area of only 60’

Problems encountered along the way….
• Few lamps survived Round 1 testing (color, output, flicker, etc.)• Product performance claims often inflated• Some lamps incompatible with electronic transformers (flicker,
loading too low)• Most lamps behaved oddly when dimmed• MR16 LED Lamps in enclosed fixtures starting failing at 9000 hours
