LED Tube Light Bulbs

Q: 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.

Q: 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.

Q: 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.

Q: 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.

Q: 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.

Q: 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 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.
