Deep Dive: 105W CFL (Compact Fluorescent) to LED

Replacing a legacy 105-watt CFL (Compact Fluorescent) (CFL) 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 CFL (Compact Fluorescent) Technology vs. LED

Energy-saving spiral or folded tube bulbs that use about 75% less energy than incandescent. Contains small amount of mercury requiring special disposal.

In contrast, Light Emitting Diode (LED) technology uses semiconductors to produce light directly from electricity, bypassing the inefficient heating or chemical arc processes of CFL (Compact Fluorescent). This results in the massive efficiency gain—dropping from 105W down to just 55W.

2. Why Upgrade to LED?

  • Instant ROI: With a savings of 48%, these lights pay for themselves typically within 6-12 months.
  • Zero Maintenance: CFL (Compact Fluorescent) bulbs typically last 8,000-15,000 hours, whereas LEDs last 50,000+ hours. That means no more ladders or lifts for 5-10 years.
  • Better Color Rendering: Old bulbs often fade or shift color. LEDs provide crisp, high CRI light which improves visibility and safety.

3. Selecting the Right Color Temperature

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

  • 3000K (Warm White): Best for residential or hospitality settings. matches halogen glow.
  • 4000K (Cool White): Ideal for offices and retail. Clean white without being harsh.
  • 5000K (Daylight): The standard for warehouses, garages, and outdoor security. Maximizes perceived brightness.

4. Installation Guide

For most 105W CFL (Compact Fluorescent) replacements, you have two main options:

  • Plug-and-Play (Type A): Works with your existing ballast. Easiest install, but eventually the ballast will fail.
  • Ballast Bypass (Type B - Recommended): Direct wire 120-277V to the socket. You remove the old ballast entirely. This is the most reliable long-term solution.
Pro Tip: Always double check your fixture's socket type. Most 105W units use E39 Mogul Base (large) or E26 Medium Base (standard household size).
