Replacing a 100W Halogen Infrared Reflective (HIR) bulb is one of the most effective ways to reduce energy costs. Modern LED replacements use only 20W to produce the same 2,800 lumens.

100W Halogen Infrared Reflective (HIR) → 18–22W LED
2,800 lumens · Uses 80% less energy
Estimated annual savings: $42.05/year (3 hrs/day at $0.13/kWh)
💡 Lumie's Tip: Halogen IR bulbs are already more efficient than standard halogens, so the LED jump is smaller — but still worth it for lifespan.

Deep Dive: 100W Halogen Infrared Reflective (HIR) to LED

Replacing a legacy 100-watt Halogen Infrared Reflective (HIR) (HIR) bulb with LED is more than just swapping a light source; it's a significant upgrade to your facility's efficiency and light quality.

1. Understanding Halogen Infrared Reflective (HIR) Technology vs. LED

Advanced halogen with infrared-reflective coating that redirects heat back to filament, improving efficiency by 30% over standard halogen.

In contrast, Light Emitting Diode (LED) technology uses semiconductors to produce light directly from electricity, bypassing the inefficient heating or chemical arc processes of Halogen Infrared Reflective (HIR). This results in the massive efficiency gain—dropping from 100W down to just 20W.

2. Why Upgrade to LED?

3. Selecting the Right Color Temperature

When choosing your replacement, you will see options like 3000K, 4000K, or 5000K. Here is a quick guide:

4. Installation Guide

For most 100W Halogen Infrared Reflective (HIR) replacements, you have two main options:

Pro Tip: Always double check your fixture's socket type. Most 100W units use E39 Mogul Base (large) or E26 Medium Base (standard household size).
