What types of projects use T8 LED tube retrofits?

T8 LED tube retrofits are used across commercial offices, warehouses, schools, hospitals, retail stores, government buildings, and industrial facilities. The most common applications involve replacing fluorescent T8 or T12 tubes in troffer fixtures, strip lights, and high-bay fixtures.

How much energy can a T8 LED retrofit save?

A typical T8 LED retrofit saves 40–60% in lighting energy costs. Replacing a 32W fluorescent T8 with an 18W LED T8 reduces energy consumption by 44%. For a 1,000-fixture warehouse running 10 hours/day, this translates to approximately $15,000–20,000 in annual energy savings.

What is the typical payback period for LED tube retrofits?

With factory-direct pricing and utility rebates, the typical payback period for T8 LED tube retrofits is 1–2 years. Without rebates, payback is typically 2–3 years. DLC-listed tubes qualify for utility rebates of $1–5 per tube, significantly improving ROI.

Do you provide project support for large-scale LED retrofits?

Yes. We provide full project support including fixture audits, product specification, sample testing, phased delivery scheduling, and post-installation technical support. Our team has supported projects ranging from 500 to 500,000+ fixtures.
