CFL Efficiency Meets Its Match in LED

Though CFLs were once a major step forward, LED technology now leads in sustainability, longevity, and performance.

Why Switch to LED?

✔ Save Up to 86% on Energy Costs – Significantly reduce overhead lighting expenses.
✔ Longer Lifespan – LEDs outlast CFLs by up to 10 times, minimizing labor costs.
✔ Instant-On, No Flickering – Ready when you are, with no warm-up period.
✔ No Mercury – Easier to handle and dispose of compared to CFLs.
✔ No Ballast Required (Type B) – Simplifies installation and eliminates common failure points.

Compatible LED Retrofit Options

Upgrading your 2G11 base fixtures is easy with flexible retrofit LED designs:

🔹 Plug & Play LED (Type A) – Works directly with existing ballasts.
🔹 Ballast Bypass LED (Type B) – Hardwires directly to line voltage, removing the ballast entirely.
🔹 Hybrid LED (Type A+B) – Future-proof solution that works with or without a ballast.
