led ballast bypass

These LED tubes are approximately 45.78–47.75 inches long. T5 tubes use miniature bi-pin G5 bases, while T8 tubes use medium bi-pin G13 bases.

Some T5 tubes offer 4 selectable color temperatures (3500K, 4000K, 5000K, 6500K). Some T8 tubes offer 5 selectable CCT options (3000K, 3500K, 4000K, 5000K, 6500K).

Many of these tubes support both installation approaches: plug-and-play use with compatible electronic ballasts (ballast-compatible) and direct-wire ballast bypass installations. Models differ, and some are specifically designed for single-end or dual-end powered ballast bypass configurations, so confirm the required wiring for the exact model before installation.

Many models support a wide input range (120–277V). For dual-end powered installations, shunted lamp holders may be acceptable; for single-end powered ballast-bypass installations, non-shunted (isolated) lamp holders are required. Check the specific tube’s installation instructions to confirm holder type and wiring.

These tubes are UL listed or UL classified, and many are DLC listed. Several models are rated for damp locations and are suitable for indoor and certain outdoor covered applications. Refer to the specific product listing for exact certifications and ratings.

Typical lifetime is listed at around 50,000 hours. Most listings include a 5-year limited warranty (often stated as a 5 YEAR WARRANTY). Check the product’s warranty terms for full coverage details.

T8 tubes include a three-way wattage switch that lets you choose between 12W, 15W, and 18W. Each setting provides a corresponding lumen output: approximately 1,620 lm (12W), 1,950 lm (15W), and 2,250 lm (18W).

Many T5 LED tubes are 24W replacements for 54W fluorescent T5HO tubes. The product descriptions state energy savings of up to about 55% compared with the higher-wattage fluorescent equivalents.

Listings report a color rendering index around CRI 83. Light-appearance options depend on the model and include values such as 3000K, 3500K, 4000K, 5000K and 6500K, with selectable Kelvin options on some tubes.
