Overview

The GY-9.5 is a high-temperature ceramic GY-9.5 lampholder socket for 500 W / 650 W (T18 / T26) lamps theatrical lamps used in KUPO Fresnel and Prism Convex fixtures. It is a service part for the hottest part of the fixture, where the lampholder has to keep electrical contact and physical shape through repeated lamp changes and long tungsten operating hours.

Why It Matters

The smaller Fresnel range still runs hot enough to punish the wrong socket material. A proper GY-9.5 ceramic holder keeps the 500 W / 650 W fixture serviceable and electrically dependable.

Key Features

• GY-9.5 ceramic socket matches the lamp base used in the specified wattage range.
• High-temperature ceramic construction holds up in the socket cavity where polymer materials would soften or deform.
• Replacement-part format supports fixture service without replacing the full Fresnel or Prism Convex body.
• Clear split from the sister socket helps crews stock the correct part for 500 W / 650 W or 1000 W / 1200 W lamp families.
