Photoflood lamp for studio use

This OSRAM BBA lamp is a 250W incandescent photoflood bulb rated for 118V operation. It produces a 3400K colour temperature suited to photographic and printing applications. The frosted envelope softens the output for even illumination. It is not intended for general home lighting.

E26 medium screw fitting

The lamp uses a standard E26 medium screw base that fits common photographic sockets and enlarger heads. No special adapter or ballast is required for the listed voltage. The 250W draw means the fixture and wiring must handle the corresponding current. It frees the user from proprietary lamp holders.

Six-lamp pack for consistent output

The supplier provides six identical lamps in one package so a studio can maintain matched colour temperature across multiple heads. Having spares on hand avoids interruptions during long print or shoot sessions. No additional accessories or software are included with the lamps.

Questions about this item

How long does the 250W filament last before it fails under continuous studio use?

Incandescent photoflood lamps like this 250W model are rated for short life; expect roughly 26 hours of continuous burning before the filament burns out.

How much heat does the 250W frosted envelope add to a small set after an hour?

Nearly all 250 watts become heat; a single lamp raises ambient temperature quickly in a confined space, so allow generous ventilation or active cooling during long sessions.

Will the E26 medium screw base fit my existing light stand or enlarger socket?

Yes, the lamp uses a standard E26 medium screw base compatible with most photographic enlargers, photoflood reflectors and printer exposure units.
