Ushio P28s porcelain socket

The Ushio P28s socket accepts medium prefocus lamps with a P28s base such as BTL, BTR, BTN, BTH, BTM, BTP, EGG, EGK, EGJ, EGM, EGF, EGE, EGC, FMC, FMD/DNT and FME/DNV types. It is built for stage, studio, film and store-display installations where reliable lamp retention matters. Buyers needing a different base format or an integrated lead set will not be served by this model.

Thermal management and rating

The holder uses a porcelain body that provides inherent heat resistance and the supplier notes exceptional thermal management properties for the product line. It is rated for 250 V and 10 A, giving a clear electrical limit for normal operation. No active cooling or noise figures are supplied.

Build and connection style

The socket ships without leads so the installer must supply and terminate wiring to suit the project. Its porcelain construction resists cracking under thermal cycling and the prefocus design keeps lamps seated during vibration. The medium P28s interface suits the listed lamp codes but will not accept smaller or larger bases.

Questions about this item

How do I mount the P28s porcelain socket without leads?

The socket accepts P28s base bulbs such as BTL, BTR, BTN, BTH, BTM, BTP, EGG, EGK, EGJ, EGM, EGF, EGE, EGC, FMC, FMD/DNT, FME/DNV; secure the porcelain body to the fixture and insert the lamp until the prefocus collar locks.

What maintenance does the Ushio P28s socket require over time?

Inspect the porcelain for cracks and the contacts for oxidation; replace the socket if the prefocus alignment shifts or the ceramic shows heat damage.

What is the first limit reached when the socket runs continuously at 250V 10A?

The 10A rating is the governing limit; sustained current above that will overheat the contacts before the 250V insulation rating becomes a concern.
