DPR Lighting Guidelines:

This document was developed as a holistic Lighting Standards Package and is shared with designers to assist in park lighting planning with a special focus on a Lighting Management Plan using the IDA and IES Principles along with addressing DPR’s needs.

Key Elements to determine:

- Lighting Management Plan (below)

- Standard Locations: ie. front doors, parking lots, walking tracks, trails

- Standard Fixtures: Pole Lights, Bollards, Wall Packs, pool decks, parking lots, etc.

- Footcandles, Kelvin, Lumens, Shielding, Dimming/Timers

Lighting Management Plan that reflects IDA and IES: “Five Principles for Responsible Outdoor Lighting.”

- Useful: All Light should have a clear purpose

- Targeted: Light should be directed only to where needed

- reduce light trespass and glare

- Low Light Levels: Light should be no brighter than necessary

- Controlled: Light should be used only when it is has a clear purpose

- Color: Use Warmer Color Lights (2200K preferred, max 2700K)

Best Practices are to install fully shielded fixtures with zero uplight with timers for cut-off times, and/or motion sensors or dimmers to reduce lighting at night when a facility or area is not in use.

Lighting at DPR’s outdoor courts and athletic fields should follow IDA’s Criteria for Community-Friendly Outdoor Sports Lighting. Sports lighting should mitigate light pollution into the community and glare into neighboring properties. Sports lighting should use the lowest luminaire Color Correlated Temperature (CCT) possible (max 5700K), while ensuring safe play is met for recreational and/or high school level sports lighting.

DPR LIGHTING STANDARDS:

This guideline is to be used for specific tasks and locations based on learned experiences and real world needs of DPR. Below are specific standard light fixtures and/or recommended Foot Candle (FC) for a variety of scenarios. BUG rating shall not exceed B1-U0-G1. The preferred luminaire shall have a nominal correlated color temperature (CCT) of 2,200K (maximum 2700K. Park light fixtures should be no more than 3500 lumens per fixture at full power. The color rendering index (CRI) shall be a minimum 70 but preferred above CRI 80. All fixtures should have 7-pin photocontrol receptacles that enable dimming based on site needs (astronomical or occupancy photocell control and timers). Black is the standard fixture color.

Area and Path Lighting: (standard or equivalent will be considered)

Option 1 (preferred):

Invue Arbor Pole Mount (ARB) for area lighting (10-14’ pole)

Option 2 (VE Option):

Invue LXS Luxescape (LXS) for area lighting (10-14’ pole)

Localized Path, Trail and Plaza Lighting:

Option 1 (preferred):

Invue Arbor Bollard (ARB)

Option 2 (VE Option):

McGraw-Edison (BRT6)

Parking Lot Lighting (Area and Site):

Option 1 (preferred):

Invue LuxeScape Arm Mount (LXS)

Option 2 (VE Option):

Invue Icon (ICS/ICM) for area lighting

Facility Perimeter Lighting:

Option 1 (preferred):

Invue ClearCurve (CCW)

Option 2 (VE Option):

Invue Entri Series (CCW)

Athletic Field and Court Lighting:

Option 1 (preferred):

Musco TLC LED (Total Light Control): 4000-5700K LED Fixture with Musco App Control.

Note: Athletic Field Lighting is typically mounted on 40’-60’ poles for recreational sports

Location of Lights and Recommended Light Levels (*from IES):

- Building Perimeter*: Average 1.5 FC (min. 0.75FC - max. 3.0FC)

- Front Doors: max. 5.0FC

- Pathways/Safety*: Average 1.0 FC (min. 0.5FC – max. 2.0FC)

- Very Urban Pathways/Safety*: Average 1.5 FC (min. 0.75FC - max. 3.0FC)

- Trails: Average 0.5FC (min 0.25FC – max. 1.5FC)

- Parking Lots*: Average 1.5 FC (min. 0.75FC - max. 3.0FC)

- Pool Decks Security (during seasonal uncovered pool only): Average 1.0 FC (min.

0.5FC – max. 1.5FC)

All of the above lighting levels are shown at 100% when facilities are in active use.

These lights should be dimmed to no more than 50% of maximum or turned off completely when facilities are not in active use. When safe passage is required during seasonal shorter days the fixtures may be dimmed to no more than 50% of maximum.

Illumination for specific sports should conform to the recommendations for play in IES RP-6-20 Lighting Sports and Recreational Areas and in IDA-Criteria for Community- Friendly Outdoor Sports Lighting. Most DPR Courts and fields will be lit for Class IV levels of play, but some designs may require Class II or III levels of lighting.

Class IV Lighting Examples:

- Basketball Courts: 20FC

- Tennis Courts: 30FC

- Athletic Fields: 20FC

- Baseball: infield: 30FC / outfield: 20FC

- Volleyball: 20FC
