Collection: Espen

Espen offers Type A, Type B, and Type C LED tubes. Type A works directly with your existing fluorescent ballast for a plug-and-play install. Type B bypasses the ballast and wires directly to line voltage for maximum efficiency and longevity. Type C uses an external driver for the best dimming performance and longest lifespan. Espen's comprehensive lineup ensures there is a solution for every retrofit scenario.

Yes. Espen's Type A tubes are designed to work directly with compatible existing fluorescent ballasts, making installation as simple as swapping out the old tube. For facilities looking to eliminate ballast maintenance costs entirely, Espen's Type B tubes allow you to bypass the ballast and wire directly to line voltage, future-proofing the fixture for decades of LED-only operation.

A ballast bypass (Type B retrofit) involves removing or disabling the existing fluorescent ballast and rewiring the fixture to run line voltage directly to the lamp sockets. This eliminates the ballast as a point of failure, reduces energy consumption (no ballast power draw), and extends the life of the LED tube. It is the preferred method for large-scale commercial retrofits where long-term maintenance savings are a priority.

Yes, many Espen LED products are DLC (DesignLights Consortium) listed, making them eligible for utility rebate programs across North America. DLC listing confirms the product meets rigorous energy efficiency and performance standards. Always verify the specific model on the DLC Qualified Products List before purchasing to confirm rebate eligibility for your utility program.

Espen backs their LED products with strong limited warranties, typically 5 years on LED tubes and retrofit kits. This reflects their commitment to quality engineering and long-term reliability. Warranty terms may vary by product line, so always check the specific product documentation for details on your model.

Yes, Espen's pre-assembled retrofit kits are specifically designed for quick installation into existing fluorescent troffers and strip fixtures. The kits include the LED board, driver, and mounting hardware needed to convert a standard 2x4 or 2x2 troffer into a high-efficiency LED fixture without replacing the entire housing. This approach saves significant labor and material costs compared to full fixture replacement.

Shunted sockets have the two contacts internally connected (shorted together), while non-shunted sockets keep them separate. This distinction is critical for Type B ballast bypass retrofits: most Type B LED tubes require non-shunted sockets. Using a Type B tube in a shunted socket can cause the lamp to fail or create a safety hazard. Always verify your socket type before performing a ballast bypass retrofit.

Switching from fluorescent to Espen LED tubes typically delivers energy savings of 40-60% depending on the existing system. A standard 32W T8 fluorescent system (including ballast draw) can be replaced with a 15-18W LED tube delivering equal or greater light output. Over a 50,000-hour lifespan, the energy and maintenance savings add up to a compelling return on investment, often paying back the retrofit cost within 1-3 years.

Many Espen LED tubes and retrofit kits are compatible with emergency battery backup drivers. For Type C systems using an external driver, emergency-rated driver options are often available. For Type B ballast bypass installations, a separate emergency battery pack can be wired into the circuit. Always consult the product spec sheet to confirm emergency compatibility for your specific Espen model.

Yes, in addition to their linear tube and troffer retrofit solutions, Espen offers LED products suited for high-bay and industrial applications. Their high-efficacy drivers and retrofit components are engineered for demanding commercial environments. For ceiling heights above 15 feet, pair Espen's high-output LED solutions with appropriate optics to ensure proper foot-candle levels at the work surface.
