Professional Halogen Lamp for Studio Lighting

The OSRAM BTN is a 750 watt tungsten halogen lamp that operates on 120 volts. It produces 17000 lumens at a colour temperature of 3200K with a colour rendering index of 100. The T7 envelope uses a C-13d filament and fits a P28s medium prefocus base. This lamp is intended for professional studio, stage and film fixtures requiring precise colour accuracy.

Thermal Output and Electrical Draw

At 750 watts the lamp generates significant heat during its 500 hour rated life. The halogen cycle maintains consistent output and colour stability throughout normal use. Fixtures must provide adequate ventilation to manage the thermal load from the single-ended T7 envelope. Power draw remains constant at the rated wattage when supplied with 120 volts.

Base and Filament Design Enable Precise Focus

The P28s medium prefocus base positions the C-13d filament accurately within compatible optical systems. This mechanical alignment ensures repeatable beam patterns for follow-spots and profile fixtures. No additional accessories or software are included with the lamp. The base and filament geometry are the only factors that affect optical performance.

Questions about this item

How do I install the P28s base without damaging the prefocus alignment?

Align the pins with the socket slots and push straight in until the base seats firmly; twisting the bulb during insertion can bend the prefocus pins and prevent proper filament positioning.

What maintenance or replacement will the 500-hour rated lamp need?

Replace the entire bulb after approximately 500 hours of operation; halogen capsules cannot be serviced and the filament will eventually fail.

At what point does the 750-watt heat output become the limiting factor during sustained use?

The 750-watt power draw generates significant heat immediately, so adequate fixture ventilation is the first limit reached during continuous operation.
