Installation Guide (Without Ballast, Single or Double Ended)

STEP 1: Power Off

a. Turn off the power by locating the circuit breaker that controls the existing fluorescent fixture and switch it off.

STEP 2: Remove Old Tube and Ballast

a. Carefully remove the old T8 fluorescent tube by gently twisting it and sliding it out of the tombstone sockets.

b. Remove the fixture cover, locate the ballast, then disconnect the ballast wires as indicated with an "X". Safely dispose of the ballast for cleaner wiring as well as reduce fire risk.

STEP 3: Wiring

Single-Ended Wiring

Determine if the wiring for the T8 will be single-ended or double-ended:

Single-Ended:

a. Before tube installation, check if the tombstones are shunted. Replace them with new non-shunted ones.

b. Place one end of the T8 (marked L and N) into the tombstone that is powered.

c. Place the other end of the T8 into the tombstone that is not powered.

Note: If the socket lamp holders are shunted, replace them with new non-shunted ones.

Double-Ended Wiring

Double-Ended:

a. Wire the Live (L) to one end of the tombstone.

b. Wire the Neutral (N) to the opposite end of the other tombstone.

c. Place the T8 tube into both ends of the tombstone socket, then twist the tube to secure it into place.

STEP 4: Finalizing Installation

a. If installing multiple T8 tubes in one fixture, follow Step 3 but run the wires for the additional lights in parallel. Refer to the wiring diagram below for assistance.

b. Turn on the circuit breaker to test the light.

Note: Do NOT power the T8 tubes if the ballast has not been removed. Failure to remove the ballast will damage the tubes and cause a fire hazard.
