Wireless Outdoor Lighting Controls Software

LightingGale is a web based or standalone outdoor wireless control system/ software package. It is used to configure, monitor, and collect data from outdoor lighting fixtures. The outdoor wireless control system constantly monitors the luminaire's sensors, schedules on and off periods, and saves energy while reducing operating costs for a significant ROI. Data for lighting management is collected from wireless sensors that replaces photocells on outdoor lighting fixtures. A gateway is used to concentrate the wireless sensor data and sends it to the LightingGale software. The wireless lighting fixture sensors manage data such as: Voltage, Current, Frequency, Power, Power Factor, Energy, and various status states of the outdoor lighting fixture (on, off, dim level). Other items gathered are possible fault conditions, such as: LED oscillating, LED Driver Fault, LED fail, photocell fail, etc. The outdoor wireless control system allows the administrator to set the LED Fixture’s state manually or automatically and to create scheduling schemes.

Wireless Lighting Controls System Overview

The wireless lighting control system has three main components:

  • A management system (LightingGale) either as a cloud based or standalone,
  • Gateways to concentrate the data from the geographically dispersed sensors, and
  • Wireless lighting fixture based sensors.

The LightingGale system supports compliance with the ASHRAE/IES 90.1-2010 energy standard, and California’s Title 24-2013 energy code.

Outdoor Lighting Controls Management System

The LightingGale wireless lighting control system is a browser-based application. It allows users to see the status of lighting fixtures, generate reports, and schedule the on-off, or dimming state of a fixture. It also provides:

  • The energy usage of the lighting system,
  • Viewing trends on from the data collected (e.g. graphical representation of various data items or settings),
  • Interacting with dashboards and alarms (Normal, Low or Critical conditions) of the lighting system or
  • Managing the fixtures in any remote site from any location.

Wireless Lighting Controls Gateway

A group of wireless sensors communicates their data to the Gateway via a Zigbee mesh network. The distributed gateways sends data via GPRS (cellular phone radio), or an Ethernet connection. In the GPRS case, a wireless telecom carrier SIM card is used by the modem to communicate with the cellular provider. From there, data is sent over the Internet to the centralized lighting control management system. The detail data received through the network are updated in the management system’s centralized database.

Sensors for Outdoor Wireless Control

The LightingGale software can be configured to work with several wireless lighting controls/ sensors. The sensor provides a replacement of the photocell functions, and adds comprehensive data about occupancy, fixture health and status. Through the lighting management system, dynamic schedules can be set from anywhere an authorized users has access to the system.

The wireless lighting control sensor is an integrated device located on the luminaries to which data is transmitted and received. An RF module in the sensor communicates with the Gateway concentrating up to 1000 individual sensors. Several models of wireless lighting fixture sensor are available:

Would you like to tell us a little more about your needs for Outdoor Wireless Controls System?

What timeframe would you need the product by?

Which of the following applications are you interested in?

DLC Listed?

The DesignLights Consortium™ (DLC) is a collaboration of utilities and energy efficiency organizations to accelerate energy efficiency measures in commercial buildings. The rebate process that many utilities use requires DLC qualified products to be installed and substantial energy savings realized. As part of the lighting rebate process, the DLC List is the first step in examining outdoor lighting and other projects for rebate eligibility. The DLC list requires LED fixture manufacturers submit test results from certified labs on the luminaires to be qualified, or 'listed' by the DLC. The reports submitted for the DLC qualification process include the LM-79 report that quantifies the LED fixtures performance, as well as, the LM-80 report that examines the actual LED light engine and uses TM-21 methods to project LED lifetimes. By submitting these reports and undergoing the DLC Qualification Process, assures that the Manufacturer of LED lighting products, have met certain minimum specifications for performance, as well as reassurance to the buyer.

DLC List - Specifications for Outdoor and other LED Lighting

For people procuring LED light fixtures, being on the DLC Qualified Product List, assures that the LED outdoor lighting manufacturer specifications have been reviewed and meet minimum performance parameters. The main DLC Qualified Product List performance specifications include:
  • Minimum light output (lumens) from the LED fixture based on lighting application type
  • Zonal Lumens - How the light output is distributed from the fixture to its lighting task
  • Minimum luminous efficiency - How many watts of energy does it take to produce light in lumens per watt
  • Correlated Color Temperature (CCT) - A measure of how the light appears from warm colors like incandescent at a 1,600K CCT to noon bright white at 5,000K CCT.
  • Color Rendering Index - An indication of how color appears under reflected light of the LED fixture. Typical HID metal halide ratings are in the CRI 60 range, incandescent light by definition is a CRI of 100.
  • Lumen Maintenance (L-70) is a projected value of when an LED light source will produce 70% of its original light output. It is listed in hours and the accepted value for the end-of-life for an LED fixture. An L-70 lifetime rating is temperature dependent and is usually listed at 25° C. An L-70 lifetime of 50,000 hours at 12 hours per day of LED fixture use is 11.4 years of outdoor lighting fixture use.
  • Warranty - The DLC requires some more tea of five years

DLC List and Rebates for LED Outdoor Lighting

LED lighting rebates are most often offered by Electric Utilities, and sometimes by State grant making organizations. Rebates are highly variable, and have many different requirements to be eligible for rebates. But in general, a product that is qualified on the DLC List is a good indication that rebates for outdoor lighting can be obtained. A good first source for finding rebate information is the DSIRE (Database of State Incentives for Renewables & Efficiency). Outdoor lighting rebates are generally of two types, qualified product rebates and performance based programs. Qualified product rebates are most often a rebate of a fixed amount per fixture replaced, while the performance based programs are based on the kilowatt hours or peak kilowatts of load electricity saved.

Rebate Process for LED Outdoor Lighting

Determination of which option is optimal in obtaining outdoor lighting rebates will require a modest amount lighting design and economic analysis. In overview, the rebate process involves:
  • Inventorying existing HID lighting fixtures,
  • Determine what lighting levels are required for the outdoor lighting application,
  • Selecting LED fixture will meet these lighting requirements at the lowest possible energy use
  • Compiling a spreadsheet of existing lighting fixtures compared to the proposed fixtures
Most utilities will require a spreadsheet that lists what HID fixture is being replaced with what DLC Listed product. The spreadsheet will often articulate the savings per fixture count, application type (e.g. garage lighting), and the total kilowatt hours saved and the load reduction in kilowatts. Based on this information the utility can quickly qualify the LED lighting installation for rebates, and give a general indication of the rebate amounts and levels. After the project is installed, most often certifications are required by the property owner that the installation has been completed, and in some cases, a site inspection will take place. The Utility or other rebate grantor will then mail a check to the property owner for the agreed rebate amount.
