Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Westinghouse 300 W T3 Utility Halogen Bulb delivers a powerful, focused glow in a compact form. With 5,000 lumens from a 120V, 300-watt design, it’s built to illuminate large work areas, display spaces, and utility rooms with crisp, bright white light.

  • Bright white output: 5,000 lumens at a color temperature of 3050K provides clear visibility for detail-oriented tasks without harsh glare.
  • Compact, precise shape: T3 bulb shape with a 1.56" diameter and 3.07" length fits tight recessed fixtures and narrow luminaires.
  • Recessed Single Contact (RSC) base ensures compatibility with compatible housings and fixtures designed for utility lighting.
  • Dimmable: Easily adjust brightness with compatible dimmers to tailor ambiance or task lighting on demand.
  • Indoor use, versatile in commercial and residential settings: Perfect for workshops, garages, basements, utility rooms, and track or recessed lighting in stores or offices.
  • Reliable performance: Average rated life of 1,500 hours provides dependable service in busy spaces.
  • Compliance and packaging: California Title 20 compliant for energy standards; packaged as a single carded bulb for convenient replacement.

This utility halogen bulb shines where other lamps fall short: it delivers instant full brightness without warm-up delay, excellent beam quality for task accuracy, and a clear finish that minimizes color distortion in workspaces. Its robust 300W output makes it a strong candidate for high-need environments like craft rooms, workshop benches, and utility corridors, while its compact size ensures it fits fixtures with limited space.

Who benefits most: professionals and DIY enthusiasts who require bright, dependable lighting for detail-intensive tasks, as well as facilities managers looking for bright, economical indoor lighting in commercial or residential spaces. If you’re upgrading from lower-lumen bulbs or seeking a high-intensity option that remains compatible with standard 120V circuits, this Westinghouse halogen bulb is a practical, purpose-built choice.

Practical tips for best results:

  • Pair with a compatible dimmer to dial in the perfect level of brightness for your task or mood.
  • Use in fixtures with adequate ventilation, as halogen bulbs can generate noticeable heat during operation.
  • Schedule replacements around the 1,500-hour average to maintain consistent illumination in high-traffic areas.
