Leviton 377 – Frequently Asked Questions

1) Will the Leviton 377 lampholder fit a standard T8 linear fluorescent lamp?
The Leviton 377 is a medium bi-pin lampholder built to seat and retain T8 bi-pin fluorescent lamps in linear fixtures. If the lamp in your fixture is a T8 with two pins on each end, this is the socket type it drops into. It will not accept single-pin (slimline) or recessed double contact (HO) lamps, which use a different holder entirely.
2) Can I use the Leviton 377 as a direct replacement socket when I re-lamp an older T8 fixture?
Replacement is one of its stated uses. The 377 is a standard-profile lampholder meant to mount into existing or new fluorescent fixture channels, so it works for swapping out a cracked or burned socket during fixture maintenance as well as for new fixture builds. Match the mounting style in your channel (the bracket or slot the old holder sat in) before you pull the old one.
3) Is the Leviton 377 lampholder plastic or metal, and does that matter in a warehouse fixture?
Thermoplastic body, not metal. For a maintenance crew that means a lighter socket that resists cracking and corrosion, which is why it holds up in damp or dusty commercial and industrial channels where a metal holder can corrode at the contacts. The trade-off is the usual one for plastic sockets: keep it away from direct high-heat contact points in the fixture.
4) What color is the Leviton 377 lampholder? I need the sockets to match across a bank of fixtures.
Black. If you are standardizing sockets across a run of office or retail fixtures where the holder is visible at the end of an open channel, ordering all 377s keeps the appearance consistent instead of mixing black and white holders down a corridor.
5) Is the Leviton 377 suitable for commercial and industrial fixtures, or is it a residential part?
Commercial and industrial linear fluorescent fixtures are exactly what it is built for, along with office, warehouse and retail lighting and renovation or new construction work. It is a Leviton wiring device, not a light-duty residential socket.
6) How do I order the Leviton 377 lampholder, and is there more than one version?
One model only, the 377, so there are no finish, color or base options to specify. Order by the Leviton 377 part number and you get the black thermoplastic medium bi-pin T8 holder.
7) Where can I get the full technical data on the Leviton 377 lampholder for a submittal?
Leviton publishes a technical information sheet for the 377, and ZenSupply carries it as a downloadable PDF alongside the product record. That is the document to attach when a spec reviewer wants manufacturer data on the socket rather than the fixture.
