Deep Dive: 25W Incandescent to LED
Replacing a legacy 25-watt Incandescent (Inc) 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 Incandescent Technology vs. LED
Traditional light bulbs that produce light by heating a tungsten filament. Very inefficient - only 2-3% of energy becomes light.
In contrast, Light Emitting Diode (LED) technology uses semiconductors to produce light directly from electricity, bypassing the inefficient heating or chemical arc processes of Incandescent. This results in the massive efficiency gain—dropping from 25W down to just 3W.
2. Why Upgrade to LED?
- Instant ROI: With a savings of 88%, these lights pay for themselves typically within 6-12 months.
- Zero Maintenance: Incandescent bulbs typically last 750-1,000 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 25W Incandescent 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 25W units use E39 Mogul Base (large) or E26 Medium Base (standard household size).
