QTX PAR36 30W Spotlight Bulb 6.4V Screw Fitting

The QTX PAR36 is a 30W spotlight bulb with a screw terminal fitting and a parabolic aluminised reflector that produces a focused narrow beam. The bulb operates at 6.4V DC, making it compatible with low-voltage PAR can fixtures commonly used in stage, theatre, event and architectural lighting installations. The sealed beam construction integrates the filament, reflector and front lens into a single replaceable unit.

Designed for PAR36 can fixtures, the bulb suits pinspot applications where a tight beam is needed to highlight specific areas on stage, illuminate performers, accent displays or create architectural wash effects. The 100-hour rated life is typical for tungsten halogen PAR lamps in professional entertainment use, where colour rendering and instant strike are prioritised over longevity. The screw terminal fitting provides a secure mechanical and electrical connection inside the PAR can housing.

The 30W power draw at 6.4V draws approximately 4.7A, so compatible power supplies and wiring must be rated to handle the current load across multiple fixtures. The PAR36 format produces a warmer colour temperature than LED equivalents, giving the incandescent glow still preferred for certain stage and theatre applications. The sealed beam design means the entire unit is replaced when the filament fails, rather than changing a separate reflector and lamp.

What voltage does this bulb require?

The bulb operates at 6.4V DC. It draws approximately 4.7A at 30W, so the power supply and fixture wiring must be rated to handle this current load. This is a low-voltage lamp, not mains voltage.

What fixtures is it compatible with?

The PAR36 format with screw terminal fitting is designed for low-voltage PAR can fixtures and pinspot housings used in stage, theatre and event lighting. Check your fixture's specification to confirm it accepts PAR36 bulbs at 6.4V.

How long does the bulb last?

Rated life is 100 hours. This is typical for tungsten halogen PAR lamps in professional entertainment use, where instant strike, warm colour rendering and dimmer compatibility take priority over lifespan. Plan for regular replacement in high-use installations.

Can it be dimmed?

Yes. As an incandescent tungsten halogen lamp, it responds smoothly to dimming via compatible low-voltage dimmers. Dimming also extends filament life but shifts the colour temperature towards warmer amber tones.
