LED T8 Tubes
Installation instructions for LT8-48XX-PRO2 and LT8-48XX-PRO3 Series
WARNING: These products may represent a possible shock or fire hazard if improperly installed or attached in any way. Products
must be installed in accordance with these instructions, current electrical codes and/or the current National Electric Code (NEC).
WARNING: Risk of fire or electric shock. Install these kits only in luminaires that have the constructionfeatures and
dimensions shown in the photographs and/or illustrations on the following pages.
READ THESE INSTRUCTIONS. SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.
WARNING: To reduce the risk of fire and reduce the risk of electrical shock, do not remove the retrofit LED tube
lamp enclosure (cover and/or caps). No user-serviceable part inside. Refer servicing to qualified service personnel.
Make sure you have all the kit components before beginning any installation:
This product is sold in cases of six retrofit kits. Each retrofit kit includes the following components: LED T8 Tube Lamp (1 pc),
T8 non-shunted lampholder (1 pc, also known as ”tombstone” or bi-pin socket), installation instructions (1 pc)
and installation labels (one label is to be used for each modified fixture).
Note: You will need 18-gauge solid copper type (not included) to complete the installation.
The end retrofit luminaire has been modified and can no longer operate the originally intended lamp.
LUMINAIRE CONVERSION RETROFIT KIT FOR USE ONLY WITH FLUORESCENT LUMINAIRES.
Models LT8-48XX-PRO2 and PRO3 Series are suitable for dry or damp location.
Do not make or alter any open holes in a wiring enclosure nor in any electrical components during kit installation!
WARNING: Risk of fire or electric shock. Retrofit kit installation requires knowledge of fluorescent lighting luminaires
electrical systems. If not qualified, do not attempt installation. Contact a qualified electrician.
WARNING: Risk of fire or electric shock. The electrical input range of this product is 100-277V AC., 60 Hz (18W -22W).
The installer must determine whether power supply is in the range of 100-277V AC at the luminaire before installation.
WARNING: Risk of fire or electric shock. Luminaires wiring, ballast(s), or other electrical parts may be damaged when
drilling for installation of reflector kit hardware. Check for enclosed wiring and components.
WARNING: Risk of fire or electric shock. Do not use this retrofit kit in luminaires employing shunted bi-pin lampholders.
Note: Shunted lampholders (also known as “tombstones” or bi-pin sockets) are found only in fluorescent luminaires with
Instant-Start ballasts. Instant-Start ballasts can be identified by the words “Instant Start” or “I.S.” or the designation “IS”
within the lamp marking on the ballast, for example F40T12-IS. For more information, contact the LED luminaire retrofit kit
manufacturer.
Note: For luminaires with starters, the starters must be disconnected from the circuit. Please do not remove the starter(s) from
the luminaire, since it would create an opening in the luminaire.
THIS PRODUCT MUST BE INSTALLED IN ACCORDANCE WITH THE APPLICABLE INSTALLATION CODE BY A PERSON
FAMILIAR WITH THE CONSTRUCTION AND OPERATION OF THE PRODUCT AND THE HAZARDS INVOLVED.
THE RETROFIT ASSEMBLY IS ACCEPTED AS A COMPONENT OF A FLUORESCENT LUMINAIRE WHERE THE SUITABILITY
OF THE COMBINATION SHALL BE DETERMINED BY UL OR AUTHORITIES HAVING JURISDICTION.
WARNING: To prevent wiring damage or abrasion, do not expose wiring to edges of sheet metal or other sharp objects.
Each lampholder (also known as “tombstone” or bi-pin socket) shall be installed only in the intended manner and location.
CAUTION - To reduce risk of fire, electric shock or injury to persons:
1. Make sure that the electrical power to the fixture is disconnected prior to any installation or retrofit.
2. Read all instructions regarding ballast bypass and non-shunted T8 socket (”tombstone”) before beginning retrofit.
3. Do not use these products in luminaires located where elevated ambient temperatures exist.
4. Caution: Risk of Electric Shock. Models LT8-48XX-PRO2 and PRO3 Series are suitable for dry or damp location.
5. Caution: Risk of Electric Shock. Do not use where directly exposed to water!
5. Not for use with dimmers.
6. This device is not intended for use with emergency exit fixtures or emergency exit lights.
7. Do not install in a raceway or luminaire marked for through branch wiring.
8. Do not use in conjunction with any type of ballast or driver. LED T8 Tubes are designed
for 100-277V AC, 60Hz input only.
9. Do not use detergents, abrasive brushes or pads to clean the polycarbonate cover.

NON-SHUNTED SOCKET INSTALLATION AND FIXTURE MODIFICATION - To replace fluorescent lamps
with LED T8 Tubes, the wiring must be retrofit according to the following instuctions. To ensure a
complete and safe installation of the LED Tubes, strictly follow this installation guide.
DANGER - RISK OF SHOCK! DISCONNECT POWER BEFORE INSTALLATION.
Note: The “live end” of the LED T8 Tube is marked with red sticker/label. See Figure 1.
I. GUIDELINE FOR RETROFIT OF INDUCTIVE AND ELECTRONIC FLUORESCENT FIXTURES:
1.
2.
3.
4.
5.
Determine which end of the luminaire will receive AC power. This will be the “live end”. The opposite end will be the “dead end”.
Be sure power is shut off at source! Remove lens or diffuser, where applicable.
Remove the fluorescent lamps and properly dipose of them since they contain mercury.
Open the ballast cover to expose the fluorescent ballast.
Cut the wires on either side of the starter (if applicable) and the ballast as shown in Figure 2, refering to INDUCTIVE or
ELECTRONIC example, depending on the luminaire type. Do not remove the starter and ballast. They must remain in place
since their removal could create openings in the luminaire housing.
6. Using 18-gauge solid copper wires, connect to branch circuit (L = Line and N + Neutral) as shown in Figure 3.
7. Using 18-gauge solid copper wire, connect ground wire (from AC supply) to ground screw or if already attached,
confirm the connection is solid.
8. Replace the ballast cover.
9. IMPORTANT: Install the fixture modification label “This luminaire has been modified and can no longer operate the
originally intended lamp” inside the fixture in an easily visible location to anyone changing lamps, possibly on the
cover over the wiring channel. See Figure 4.
10. Install the LED tubes, rotating pins in the “tombstone” sockets until fully seated. Replace the lens/diffuser, where applicable.
11. After the LED tubes are installed and lens/diffuser is in place, restore the power at the circuit breaker and turn the lights on.

NOTE: LED lamp pins at the “live end” are connected to power. The other end is not connected to any
electrical power and that bi-pin (tombstone) socket serves as means of mechanical support only.
THE END RETROFIT LUMINAIRE HAS BEEN MODIFIED AND CAN NO LONGER OPERATE THE ORIGINAL INTENDED LAMP(S).

NON-SHUNTED SOCKET INSTALLATION AND FIXTURE MODIFICATION (continued from previous page)
5. Remove the end cap of the luminaire’s housing and remove the existing sockets (also known as a “tombstones”) from the live
end for each LED T8 Tube by lifting or unseating them from mounting slots. See Figure 3.
7. Cut one black and one white 18-gauge solid copper wire (not included) to approximately 12” length and strip ends to 3/8”.
Cut one more or each color wire, making sure you have enough wire to reach from the end of the luminaire to the supply wires
(approximately 30”).
8. For a two light luminaire, attach 12” black and white wires between sockets and longer lengths to one socket, providing
lead wires to reach supply wires. See Figure 5.
9. Push the new sockets into the mounting slots until they are flush. See Figure 6.
10. Replace the luminaire’s end cap with the new sockets securely mounted to the live end of the luminaire. See Figure 7.
11. Attach lead wires from new sockets to supply wires, making sure to match polarity (connect black to black and white to white),
using appropriate UL Listed wire nuts. See Figure 8.
12. Cut back any remaining wires from the socket(s) at the “dead end” and cap off with a UL Listed wire nut. Leave this socket
in place to hold the LED T8 Tubes. See Figure 9.
13. Replace ballast cover.
14. Attach warning sticker to ballast cover in a conspicous spot for reference: “This fixture has been modified - the ballast has
been removed. Do not install fluorescent lamps in this fixture!!”
15. Replace any lenses that were removed.
16. Turn back on power supply.
