HALO VT 100-Watt Incandescent Vapor Tight Flood Light

This vapor tight incandescent flood light adds a durable bulb guard and weather-resistant construction. It’s suitable for barns, workshops, sheds, and livestock areas where rugged exterior lighting is needed. Installation supports ceiling or wall mounting through accessible 1/2 in. conduit openings.
Best for: buyers who favor simple incandescent illumination and need a rugged, guard-protected outdoor fixture. Choose this if you prefer a traditional bulb setup and straightforward mounting in exposed outdoor spaces.

Buying Guide: Vapor Tight Barn Lighting Essentials
What weather rating do I need? Look for IP65 or higher for outdoor use and areas with high moisture. IP65 means protection against water jets and dust ingress.
LED vs incandescent: LED fixtures save energy and have longer lifespans, reducing maintenance in large barns or workshops. Incandescent options are simpler but less efficient.
Wattage and brightness: For wide barn spaces, aim for higher lumen output (6000–8000 lm) with a 4000K–5000K color temperature for clear, natural-looking light. For smaller nooks, 3000K warm white can be preferable for comfort.
Color temperature: 4000K is versatile for work areas; 5000K–6500K suits tasks requiring high contrast. Dimmable drivers add flexibility but confirm compatibility with your dimmers.
Durability and mounting: Consider fixtures with rugged housings and easy mounting options (ceiling or wall). A bulb guard is beneficial in high-traffic or livestock areas to prevent damage.
