What's the difference between Type A, Type B, and Type A/B LED tubes?

Type A tubes run on the fixture's existing ballast (plug-and-play, no rewiring). Type B tubes bypass the ballast and wire directly to line voltage. Type A/B hybrids can be installed either way, giving you flexibility on a retrofit.

What is the difference between T8 and T5 LED tubes?

It is the diameter. T8 tubes are one inch across and are the standard fluorescent replacement, while T5 tubes are a slimmer 5/8 inch, often higher output, and common in newer high-efficiency fixtures. They are not interchangeable, so match the tube to your fixture.

Can I put LED tubes in my existing fluorescent fixtures?

Yes - that is exactly what they are designed for. Choose Type A to reuse the existing ballast with no rewiring, or Type B or Type A/B to bypass the ballast and wire the tube directly.

Do LED tubes need a ballast?

It depends on the type. Type A tubes use the existing ballast, Type B tubes remove it and wire directly to line voltage, and Type A/B tubes can work either way. Removing the ballast (Type B) eliminates a common failure point but usually requires an electrician.

What wattage LED tube replaces a 32W fluorescent?

A 32W fluorescent T8 is typically replaced by a 15 to 18W LED tube, depending on the lumen output you want. LED tubes generally use around half the wattage for comparable light.

What lengths and color temperatures are available?

LED tubes come in 2, 3, 4, and 8 foot lengths and color temperatures from about 3000K to 6500K - 3500K or 4000K is common for offices and 5000K for shops and task areas.

LED Tube Light Bulbs

LED tube lights are energy-saving replacements for traditional fluorescent tubes that drop into the troffers, strip fixtures, and direct/indirect fixtures already in offices, schools, retail, warehouses, garages, and more. They last far longer than fluorescent — typically 20,000 to 50,000 hours — and usually draw around half the wattage, making them one of the easiest, highest-return lighting upgrades you can make. This collection covers T8 and T5 LED tubes in 2, 3, 4, and 8 foot lengths, in ballast-compatible (Type A), direct-wire (Type B), and hybrid (Type A/B) versions.
