Frequently Asked Questions
QWhat is a 4ft T8 LED tube?
A 4ft T8 LED tube (1200mm) is the most common commercial LED lighting product, replacing the 32W F32T8 fluorescent tube. Cornea Lighting's 4ft T8 LED tubes range from 9W to 22W, delivering 1,100 to 2,800 lumens. They are available in Type A (ballast-compatible), Type B (direct-wire), and Type A+B (dual-mode) configurations, with DLC QPL, UL, ETL, and CE certifications.
QWhat is the difference between Type A and Type B 4ft T8 LED tubes?
Type A 4ft T8 LED tubes work with existing fluorescent ballasts — no rewiring required. Type B tubes bypass the ballast and wire directly to 120–277V line voltage. Type B is more efficient (no ballast energy loss), more reliable (no ballast failure), and preferred for large commercial retrofits. Type A is faster to install but depends on ballast compatibility.
QDo 4ft T8 LED tubes qualify for utility rebates?
Yes. All Cornea Lighting 4ft T8 LED tubes are DLC QPL listed, qualifying for utility rebate programs across the US and Canada. Rebates typically range from $5–$25 per tube depending on the utility provider. Rebate eligibility can reduce project payback period from 3 years to under 18 months.
QWhat CCT options are available for 4ft T8 LED tubes?
Cornea Lighting offers 4ft T8 LED tubes in 3000K (warm white, for hospitality and retail), 4000K (cool white, for offices and schools), and 5000K (daylight, for warehouses and industrial). CRI 90+ is available in 4000K for retail display and healthcare applications.
QWhat is the minimum order quantity for 4ft T8 LED tubes?
MOQ for 4ft T8 LED tubes is 100 pieces for wholesale orders. OEM/private label orders (custom branding, custom CCT, custom packaging) start at 500 pieces. Sample orders (1–10 pcs) are available for project specification and testing.
QWhat is the lifespan of a 4ft T8 LED tube?
Cornea Lighting 4ft T8 LED tubes are rated at L70 ≥ 50,000 hours — meaning they maintain at least 70% of initial lumen output after 50,000 hours of operation. This is 2.5× longer than standard fluorescent tubes (20,000 hours), significantly reducing maintenance costs.
