Quickstart Guide

Single-Ended Installation (Non-Shunted Compatible Only)
Double-Ended Installation (Non-Shunted & Shunted Compatible)

Installation Guide (Single-Ended, Without Ballast)

STEP 1
a . Turn off the power: Locate the circuit breaker that controls the existing fluorescent fixture and switch it off.b. Carefully remove the old T8 fluorescent tube by gently twisting it and sliding it out of the socket.Note: If the socket lamp holders are shunted, replace them with new non-shunted ones.

STEP 2
a . For single lamp installation, properly install the lamp with L and N markings into wired lamp holder end (Figure 1).
b. For multiple lamp installation, ensure a link between a separate neutral wire from primary source lamp holder’s “Neutral OUT” and connect it to the “Neutral IN” terminal on the adjacent tube (Figure 2).

STEP 3
a. Turn on the circuit breaker and test light.Single-Ended Wiring DiagramInstallation Guide (Double-Ended, Without Ballast)

STEP 1
a . Turn off the power: Locate the circuit breaker that controls the existing fluorescent fixture and switch it off.b. Carefully remove the old T8 fluorescent tube by gently twisting it and sliding it out of the socket.c. Open and remove the wiring compartment cover of the ballast. Verify the Live and Neutral wires from the breaker box to the ballast and use a voltmeter to confirm the power is off.

STEP 2
a . Check if the fixture has non-shunted or shunted G13 bi-pin lamp holders:

• Refer to Wiring Diagram A in Step 3 if holders are NON-SHUNTED.
• Refer to Wiring Diagram A in Step 3 if holders are SHUNTED.

STEP 3
Wiring Diagram A (NON-SHUNTED ONLY)
a. Disconnect any wires connected to the ballast as indicated by an “X” on the wiring diagram. Safely dispose of the ballast and fluorescent lamps, following local government regulations.
b. Connect one wire to L (Live) and the other to N (Neutral). Repeat this step for the socket on opposite side.
c. Connect wires of (L) to the BLACK wire of your power supply and connect wires of (N) to the WHITE wire of your power supply.
WARNING: DO NOT CONTACT OPPOSITE SOCKET WIRES, THIS WILL CAUSE THE LAMP TO SHORT CIRCUIT.Wiring Diagram A: Non-Shunted Double-Ended Wiring

STEP 3
Wiring Diagram B (SHUNTED ONLY)
a. Disconnect any wires connected to the ballast as indicated by an “X” on the wiring diagram. Safely dispose of the ballast and fluorescent lamps, following local government regulations.
b. Connect one wire to the shunted socket . Repeat this step for the socket on the opposite end.
c. Connect the BLACK wire from your power supply to the first socket. This will be your L (Live) connection.
d. Connect the WHITE wire from your supply to the opposite socket. This will be your N (Neutral) connection.
WARNING: DO NOT CONTACT OPPOSITE SOCKET WIRES, THIS WILL CAUSE THE LAMP TO SHORT CIRCUIT.Wiring Diagram B: Shunted Double-Ended WiringSTEP 4
a. Turn on the circuit breaker and test light.

Light Distribution Angle

Lighting distribution angle refers to the spread of light emitted from a light source. It is an important factor to consider when selecting a fixture or bulb, as it affects the way it will illuminate an area. There are two main types of lighting distribution angles:
A symmetric lighting distribution emits light evenly in all directions, creating a cone-shaped pattern that provides a pool of light. This type of lighting is ideal for general lighting and illuminating large areas. Common applications for symmetric lighting include general area illumination, security lighting, and perimeter lighting. Symmetric lighting is also used to a certain degree in up-lighting.
An asymmetric lighting distribution angle, also known as beam angle, creates a pattern that focuses light in a specific direction. This type of lighting is ideal for task lighting as it reduces glare and light spill in other areas. Common applications include task lighting in spaces such as landscape settings, retail stores, museums, and much more.
It is important to note that the lighting distribution angle can also be affected by other factors such as the reflector design of the light source, the type of lens used, and the distance between the light source and the surface being illuminated.
