Keystone KT-LED31T8-72P2SO-8CSK-DX2 – Frequently Asked Questions

1) Do I have to remove the fluorescent ballast to install this 31W LED sign tube?
Yes. Wiring method is single plus double ended, meaning it wires direct to line voltage at one or both ends. The existing fluorescent ballast comes out and the sockets are wired to 120-277V line power. Input voltage range is 120-277V, so it works on either leg of a typical commercial service without changing lamps.
2) How do I set the color temperature on this color select sign tube?
Color is selectable between 4000K, 5000K and 6500K on the tube itself, chosen at install rather than ordered as separate part numbers. One stocked item covers all three, which is why a property manager with mixed cabinet signs can standardize on a single lamp and still match 6500K daylight channel letters next to 4000K neutral panels. CRI is greater than 80.
3) Can I put this LED sign tube on a dimmer or an occupancy control?
No. The tube is non-dimmable and has no wireless control capability. Feed it switched line voltage only. Putting it on a dimming circuit or a 0-10V driver is not a supported installation.
4) Will a 360 degree beam angle LED tube light a double-faced sign cabinet evenly?
Beam angle is 360 degrees and the housing is frosted plastic, so output wraps the full circumference instead of throwing in one direction. That is what you want in a double-faced or back-lit cabinet where the lamp sits between two faces. For single-faced channel letters a directional sign tube puts more of the light where it counts.
5) Can I buy this Keystone sign tube for a job in California or Vermont?
There is no sale restriction flagged for California or Vermont on the KT-LED31T8-72P2SO-8CSK-DX2. It is not DLC or DLC Premium listed and not Energy Star qualified, so if your project is chasing a utility rebate that requires a DLC listing, this lamp will not qualify for it.
