500 W Halogen Lamp with P28s Base

This 500 watt halogen bulb operates on a 120 volt supply and uses a P28s medium prefocus base. It is intended as a direct replacement for fixtures requiring the 54648 part number. The T5 shape suits stage, studio and specialist lighting applications.

P28s Medium Prefocus Base and T5 Shape

The medium prefocus base ensures precise filament alignment in compatible sockets for consistent beam performance. A T5 tubular envelope allows the lamp to fit narrow housings where wider bulbs cannot be installed. Rated life is 2000 hours under normal operating conditions.

10000 Lumens at 3000 K with CRI 100

The lamp delivers 10000 lumens at a warm 3000 kelvin colour temperature. A colour rendering index of 100 provides accurate colour reproduction for critical viewing tasks. Buyers needing higher output or a different colour temperature should select an alternative model.

Questions about this item

What voltage and base type does the 54648 halogen bulb require?

The bulb runs on 120 volts and uses a P28s medium prefocus base.

What physical space does the T5 shape need in a fixture?

The T5 tubular envelope fits standard sockets that accept a P28s base; verify the fixture’s maximum length and diameter clearance before installing.

How do I install the P28s base correctly and avoid the common seating error?

Align the two prefocus pins with the socket slots, push straight in until the base seats fully, then give a slight clockwise turn to lock; forcing it at an angle bends the pins.
