Legacy CFL Technology – But LEDs Are the Future 

While CFLs were an energy-saving upgrade from incandescent bulbs, LED technology now provides even greater efficiency, longer lifespan, and superior lighting quality. 

Why Upgrade to LED? 

✔ Up to 86% Energy Savings – Lower electricity costs with higher efficiency. 

✔ Longer Lifespan – LEDs last 5-10 times longer, reducing replacements. 

✔ Instant-On Performance – No flickering or warm-up time, just full brightness immediately. 

✔ Mercury-Free Lighting – A safer and eco-friendly alternative. 

✔ No More Ballast Failures – Many LED retrofits bypass the ballast, eliminating maintenance costs. 

LED Retrofit Options – A Smarter Lighting Choice 

Upgrading is simple with three LED retrofit options: 

🔹 Plug & Play LED (Type A) – Works with existing CFL ballasts for an easy, no-rewire swap. 

🔹 Ballast Bypass LED (Type B) – Connects directly to line voltage, eliminating the need for a ballast. 

🔹 Hybrid LED (Type A+B) – Works with or without a ballast, providing long-term flexibility.
