Status of PG&E Rebates
Current rebates cover 20-25% of fixture costs New rebates expected to be announced in Oct. Rebates will likely decline, could be eliminated Timing of change TBD, certainly 2014
Timing is becoming important

Spec Issues: Other cities practices
Lighting level CCT CRI BUG
Los AngelesMinimum lumens per RP-8 4,000 ± 275K Min of 65
100w: Cutoff or using TM-15: B1 U1 G1
San Jose
New Construction: Luminance per RP-8-05
Retrofit: current lighting levels, equal or greater (generally RP-8-64) 4,200 ± 300K Min of 70
No cut-off; G2 per TM-15, Addendum A
HaywardCurrent levels (equal or greater) 4,000 K +/- 300K Min of 65
Cutoff or TM-15:B3 U1 G2
Oakland Luminance RP-8-83 4,000 K +/- 300K Not specified Not Specified
Sunnyvale Lumens based RP-8-05TBD
(6,000 K +/- 500) Min of 70 B1 U1 G1; B2 U1 G2

Application Considerations
Applications include: road type, pole heights, spacing, conflict
Different applications require different light levels Different applications result in different footcandles on
ground for same lumens Determining right fixture requires:
Light level target Application Mapping light levels to fixtures for given application
Fixture selection based on lumens Lab verified product spec values

Next Generation Streetlight Initiative
Next Steps: Application & light level
1. Cities know application & levels If similar to SVL, use SVL analysis Possibly use SEAD tool for determining lumen requirements Do photometric analysis for exception cases
2. Don’t know application Sample & extrapolate (some inventory still likely required
but less extensive) Contract inventory to include application specifics
3. Don’t know light level Adopt RP-8 as guideline Use existing light level
May need photometric analysis13
Next Generation Streetlight Initiative
Procurement Options: Fixture selection
1. Agency: comprehensive inventory & analysis by Agency to select fixtures in procurement
2. Vendor: Provide typical scenarios and lighting level requirements to vendor
3. Vendor: Objectives based (RP8, savings, improve quality, etc.)
