Type A vs Type B vs Hybrid LED Tubes: Which One Should You Buy?
By Shaun Dravidson
Fluorescent tubes have lit offices, stores, and warehouses for decades. Now LED tubes are replacing them because they use less power, last longer, and contain no mercury. When you start shopping, though, you see labels like Type A, Type B, and Type A+B. If you pick the wrong one, you could end up with flickering lights, extra labor, or a return. This guide explains each type in simple words so you can choose with confidence.
What Do Type A, Type B, and Hybrid Mean?
These labels come from UL, the group that tests electrical products for safety. They have nothing to do with brightness or quality. They only tell you how the LED tube gets its power inside an old fluorescent fixture. A Type A tube uses the ballast that is already there. A Type B tube skips the ballast and runs on building power. A hybrid tube can do both. Once you understand that, the rest is easy.
Type A LED Tubes: The Easiest Swap
Type A tubes are often called plug and play. You remove the fluorescent tube, push the LED tube into the same sockets, and turn the lights back on. There is no rewiring, and in most cases you do not need an electrician. That makes Type A a smart choice for leased spaces, busy stores, and offices that cannot shut down for wiring work.
The downside is the ballast. It stays in the fixture, keeps using a little power, and keeps getting older. When it fails, your new LED tube goes dark too, and you have to buy and install a new ballast. Type A tubes also only work with certain ballasts, so each tube comes with a compatibility list. Most will not run on old magnetic T12 ballasts.
Before you order, take a photo of your ballast label and check it against the tube's list. That one step prevents most problems.
Type B LED Tubes: Remove the Ballast for Good
Type B tubes are also called ballast bypass or direct wire tubes. An electrician removes the ballast and connects building power straight to the sockets. The driver that runs the LEDs is built into the tube.
With no ballast, there is one less part to fail and nothing to replace later. You also save a little energy. For large buildings, this usually makes Type B the lowest-cost option over time.
The tradeoff is more work at the start. A licensed electrician should do the job, and the wiring must match the tube. Some tubes are single-ended (power at one end) and others are double-ended (power at both ends). The fixture should also get a "modified for LED" sticker so nobody puts a fluorescent tube back in later.
Hybrid LED Tubes: Flexible and Future-Ready
Hybrid tubes, also called Type A+B, work on a compatible ballast or on direct power. You can install them today with no rewiring, just like Type A. Later, when a ballast fails, your electrician bypasses it, and the same tube keeps working.
Hybrids cost a bit more per tube. They are a great fit for buildings with mixed fixtures, unknown ballasts, or budgets that need to be spread over time.
The Real Cost Is the Ballast, Not the Energy
Many guides say Type B saves more energy than Type A. That is true, but the difference is small. The bigger cost with Type A is the aging ballast.
Picture 100 four-foot tubes in 50 fixtures, running 3,000 hours a year at $0.13 per kWh. Add a few ballast failures each year, and Type A can cost around $430 more per year than Type B. Bypassing all 50 fixtures might cost $1,000 to $1,250 in labor, which pays for itself in about 2.5 to 3 years. Your numbers will vary, but on larger jobs, removing the ballast pays off.
So, Which LED Tube Should You Buy?
● Choose Type A if your ballasts are fairly new, the job is small, or you cannot rewire right now.
● Choose Type B if your ballasts are old, flickering, or magnetic, or you are upgrading a large space you plan to keep.
● Choose Hybrid if you are not sure what ballasts you have, or you want to swap now and rewire later.
A Few Things to Check Before You Order
If you choose Type B, ask your electrician to check the sockets. There are two kinds, shunted and non-shunted, and single-ended Type B tubes need non-shunted sockets to work safely.
If you have older T12 fixtures, LED T8 tubes fit the same sockets. Most T12 fixtures use magnetic ballasts, though, so Type B or a hybrid is usually the better pick. For 8 ft tubes, check the base type (FA8 or R17d) before you buy.
Why Now Is the Right Time to Switch
Fluorescent tubes are being phased out across the US. More than a dozen states and Washington, D.C., now restrict their sale, and Illinois will stop selling linear fluorescent tubes on January 1, 2027. Tubes already in your ceiling can stay, but replacements will get harder to find and cost more.
Frequently Asked Questions
Can I switch to LED tubes without rewiring?
Yes. Type A and hybrid tubes work with your existing ballast, as long as it is on the tube's compatibility list.
Is it safe to bypass a ballast myself?
Bypassing a ballast means working with building power, so a licensed electrician should do it.
What happens if I put a Type B tube in a fixture that still has a ballast?
It will not light, and it can be damaged. Only hybrid tubes work both ways.
Which LED tube is best for a warehouse?
For large warehouses you plan to keep, Type B is usually the best value because it removes ballast failures for good.
Final Thoughts
No single LED tube is best for every building. Type A is the fastest, Type B costs the least over time, and hybrids let you decide later. Match your choice to your ballasts, your budget, and how long you plan to stay.
