Do you have a question about the Lithonia Lighting TDD LED 2 and is the answer not in the manual?

This document describes the Lithonia Lighting Dusk to Dawn LED Area Light, model TDD LED 2, an outdoor lighting fixture designed for low-maintenance, energy-efficient illumination.

Function Description:

The TDD LED 2 is a dusk-to-dawn LED area light, meaning it is equipped with a photocontrol sensor that automatically turns the light on at low light levels (dusk) and off when sufficient ambient light is detected (dawn). This automated operation makes it suitable for continuous outdoor illumination without manual intervention. The fixture is intended for general outdoor area lighting applications, providing consistent light output.

Important Technical Specifications:

The manual provides a fixture packing list that details the components included with the device:

1 Housing Assembly
1 Photocontrol
2 1" Bolts (contained in parts packs)
3 2" Wood Screws (contained in parts packs)
1 Cover Plate (contained in parts packs)
3 Wire Nuts (contained in parts packs)
1 Diffuser (contained in parts packs)

Mounting hardware is included for wood surfaces. However, waterproof supply fittings, conduit, and silicone sealant are required but must be purchased separately. The fixture is designed for use with UL-listed conduit connectors, conduit, and junction boxes suitable for wet locations and properly installed and grounded. The LED light provides low-maintenance service, eliminating the need for bulb changes. The device operates on standard line voltage, which should be verified against the luminaire label information. It is not suitable for use with dimmers, motion sensors, or other remote devices.

Usage Features:

The installation process involves several steps to ensure proper functionality and safety:

Component Check: Users must first remove and check all fixture components and parts packs, ensuring all parts are present. Small parts should be accounted for, and packing material should be destroyed to prevent hazards, especially to children.
Power Disconnection: Before any installation or servicing, power must be turned OFF at the circuit breaker box. Relying solely on a wall switch is insufficient.
Photocontrol Installation: The photocontrol is installed by aligning an arrow on its top with an arrow on the receptacle, then pushing down and twisting clockwise until it clicks. For optimal performance, the photocontrol's arrow should face north after installation. If adjustment is needed, the screw in the center of the white photocontrol receptacle can be loosened, the receptacle rotated to face north, and the screw re-tightened. A stop mechanism prevents the receptacle from turning completely around. If difficulty is encountered, turning in the opposite direction is suggested. It is crucial to keep the photocontrol or a shorting cap installed to prevent water ingress into the receptacle.
Fixture Mounting: The fixture is designed for mounting to structurally sound wood surfaces. Optional mounting arms are available separately. Installation involves marking pilot holes (3/16" diameter) using a template from the box. Two 2" screws are partially installed in the bottom holes, leaving about 3/8" space. A third 2" screw is threaded into the top pre-drilled hole and then backed out to facilitate installation. The fixture housing is then placed on the two bottom screws, the third screw is installed, and all bottom screws are tightened to secure the fixture.
Wiring: Power must be turned off before wiring. A knockout on the bottom of the cover plate is removed to feed house supply wires through. The fixture is intended for use with UL-listed conduit connectors, conduit, and junction boxes suitable for wet locations and properly installed and grounded.
Grounding: The copper house supply ground wire is connected to the green fixture ground wire using a wire nut. If the house wiring lacks a ground wire, local electrical codes should be consulted for approved grounding methods. Wire nuts should be twisted clockwise until tight for proper connection.
Supply Wire Connection: Black fixture wire is connected to black power supply wire, and white fixture wire (neutral) is connected to white supply wire using wire nuts.
Cover Plate Securement: The cover plate is secured to the housing with two 1" bolts.
Diffuser Installation (Optional): If desired, the decorative diffuser is installed by aligning its keyholes with the three screw heads around the fixture's bottom, pushing up, and rotating counter-clockwise to secure it.
Power Activation and Testing: Electricity is turned on at the fuse or circuit breaker box to verify successful installation. Testing should be done at night or by blocking the photocontrol.
Moisture Seal: Silicone caulking (not included) is applied for a moisture seal.

Maintenance Features:

The TDD LED 2 is designed for low-maintenance service, as it uses LEDs and does not require bulb changes.

Cleaning: Surfaces should be cleaned with mild soap and water. Abrasive materials such as scouring pads, powders, steel wool, or abrasive paper should not be used.
Troubleshooting Guide: A comprehensive troubleshooting guide is provided for diagnosing and correcting issues if the fixture fails to operate properly.
- Basic Checks: Verify that power is on at the switch and breaker, the fixture is wired properly, and the line voltage is correct.
- Photocontrol Test: To test the photocontrol, cover it (light should turn on) or shine a flashlight into it (light should turn off).
- Cycling On/Off: If the fixture cycles on and off, it indicates light reflecting from surrounding surfaces is entering the photocontrol. Repositioning the fixture or eliminating reflective surfaces can correct this.
Technical Support: For further technical assistance, users can contact Technical Support at (800) 279-8041.
No User Serviceable Parts: The manual explicitly states that there are no user-serviceable parts inside the fixture, implying that any internal issues requiring repair should be handled by qualified personnel or through warranty service.
