Key Features & Benefits
130 LM/W High Efficacy
Industry-leading efficacy means more light per watt. A 40W retrofit produces 5,200 lumens—equivalent to a 100W fluorescent tube. Maximum energy savings without compromising illumination.
Direct Retrofit Installation
Designed for direct replacement of existing fluorescent strips. Same mounting brackets, same electrical connections. No fixture modification required. Typical installation: 15-20 minutes per fixture.
Universal Voltage Input
AC120-277V input works with most commercial electrical systems. No need to verify line voltage before installation. Suitable for 120V, 208V, 240V, and 277V circuits.
Long 50,000 Hour Lifespan
Quality LED chips and drivers ensure reliable operation. 50,000+ hour rated life means 10+ years of maintenance-free service at 12 hours daily operation. No lamp changes, no ballast replacements.
Quality Light Output
Available in 3500K, 4000K, and 5000K color temperatures. CRI >80 ensures accurate color rendering. Flicker-free driver protects eye health.

Frequently Asked Questions
Can I install these myself?
Basic electrical knowledge required. If comfortable working with household wiring, installation is straightforward. Otherwise, hire a licensed electrician. Most installations take 15-20 minutes per fixture.
Do I need to remove the ballast?
Yes, for most installations. Direct wire bypass eliminates ballast losses and ensures full LED efficiency. Some electronic ballasts may be compatible—check product specifications.
What’s the difference between retrofit and new fixtures?
Retrofit LED strips install into existing fluorescent fixtures, saving labor and material costs. New fixtures replace the entire housing. Choose retrofit when existing fixtures are in good condition; choose new fixtures for renovations or new construction.
Are these dimmable?
Standard models are non-dimmable. 0-10V dimmable versions available upon request. Specify dimming requirements when ordering.
