250W T3 Halogen Bulb by Satco

The S3184 from Satco is a 250-watt T3 double-ended halogen bulb designed as a replacement lamp for fixtures that use an R7s base. It produces 4,500 lumens of 2900K light. Key features include a 100 CRI (Color Rendering Index), a 360-degree beam, and dimmable operation.

Key Features and Benefits of This Halogen Bulb

The 4,500-lumen output delivers strong, bright light from a compact 3.13-inch lamp. A 100 CRI means colors look true, which is useful where accuracy matters. The 2900K tone is warm white, and the lamp is listed as dimmable so output can be adjusted.

Where to Use the S3184 Halogen Bulb

This bulb fits fixtures designed for T3 double-ended R7s lamps that need high output and a wide 360-degree spread. It has a damp-location safety rating, so it is not listed for wet locations. Rated life is 1,500 hours, so it suits fixtures that are easy to relamp.

Installation and Compatibility Checks

Confirm your fixture has an R7s base and is rated for 250 watts at 120V, since halogen lamps run hot. The overall length is 3.13 inches, so check the lamp fits. If you use a dimmer, confirm it is rated for halogen loads of this wattage.

Additional Buying Context

The page lists RoHS compliance only, and warranty terms and quantity per package are not stated. Halogen lamps use more energy than LED options, so consider an LED lamp with the same base if lower running costs matter more than this output and color quality.
