Deep Dive: 28W Fluorescent Tube to LED
Upgrading a legacy 28-watt Fluorescent Tube fixture to LED provides a highly lucrative return on investment for commercial buildings and industrial facilities. The massive energy savings combine with virtually zero maintenance requirements to yield rapid paybacks.
1. Linear Retrofitting: legacy vs. LED
Replacing traditional linear fluorescents with LED tubes cuts power draw by over 50%. LEDs are also instant-on and operate hum-free.
3. Why Upgrade Commercial Facilities?
- Drastic Utility Bill Reduction: Cutting lighting power draw by over 50% immediately drops energy costs, especially for fixtures operating 12+ hours daily.
- Eliminate Maintenance Overhead: Commercial fixtures are often located on high ceilings or poles requiring ladder or lift rentals. With a 50,000+ hour lifespan, LEDs eliminate re-lamping calls for years.
- Rebate Eligibility: Many commercial LEDs are DLC listed, qualifying your business for utility company energy efficiency rebates.
- Instant Full Brightness: Unlike legacy lamps that require minutes to warm up or restrikes, LEDs turn on instantly at 100% brightness.
4. Selecting the Right Color Temperature
- 4000K (Cool White): Excellent for retail spaces, grocery stores, and general office areas.
- 5000K (Daylight): The standard for warehouses, high bay facilities, parking lots, and outdoor security areas.
5. Commercial Installation Options
Retrofitting commercial and industrial fixtures offers two main options:
- Ballast Bypass (Type B - Recommended): Disconnect or remove the existing ballast entirely and wire the line voltage (120–277V) directly to the socket. This removes the ballast as a failure point, maximizing fixture reliability and longevity. We strongly recommend having a licensed electrician perform this upgrade.
- Plug-and-Play (Type A): Direct replacement that works with the existing ballast. While easier to install initially, the ballast remains a point of failure that will eventually require replacement.
⚠️ CRITICAL SAFETY WARNING: Most high-output commercial LED retrofits require a ballast bypass (Type B) installation. Operating a Type B LED bulb connected to a live ballast will damage the bulb or create a safety hazard. Always check the bulb specifications and ensure the ballast is bypassed before installation.
