Bright 500 W Halogen Source

This OSRAM halogen bulb delivers 12800 lumens at 3200 K with a CRI of 100. The double-ended R7s design fits recessed single-contact sockets. Rated life is 400 hours. It produces a whiter light than traditional incandescent lamps.

Fits R7s Fixtures Directly

The lamp installs into any fixture with an R7s recessed single-contact base. No external ballast or driver is required. It operates on standard 120 V mains supply. The compact linear form leaves space inside tight housings.

Ideal for High-Output Worklights

Suits users needing maximum brightness from a single linear halogen lamp. Not suited for buyers who want longer service intervals or lower heat output. Not suited for fixtures that accept only single-ended bases. Not suited for dimming circuits unless the fixture specifies compatibility.
