8 Best Dimmable LED Tubes of 2026
Eight dimmable LED tubes compared on length, brightness, and ballast type.
By Ethan Cole
Updated November 13, 2026
Dimmable LED tubes need the right dimmer, ballast, or driver, and the listing says which. This list covers eight LED tubes whose listings say they are dimmable. Compatibility varies by tube and dimmer, so check the maker’s notes before you buy.
See our best LED tube lights list for the rest. If you would rather replace the whole fixture, see our best LED shop lights and best 4 ft LED shop lights.
Note: switch the power off at the breaker and let a tube cool before you change it. Check the tube type against your fixture: a Type A tube is meant to work with the existing ballast, a Type B tube bypasses the ballast and needs the fixture rewired, a Type A+B tube is listed to work either way, and a Type C tube uses an external driver. Rewiring a fixture is electrical work, so use a licensed electrician if you are not experienced. Look for a UL or ETL mark, check whether the fixture is rated for the location, and follow the maker’s instructions. Listings differ; we describe what each maker lists.

How to Choose Dimmable LED tubes
Dimming
Only tubes listed as dimmable should go on a dimmer, and many dimmable tubes need a specific dimmer or driver. Check the maker’s compatibility notes.
Ballast Type (A, B, C)
Type A tubes are meant to work with an existing compatible ballast. Type B tubes bypass the ballast, which means the fixture is wired straight to line voltage. Type A+B tubes are listed to work either way. Type C tubes use an external driver. Check the listing for the type, and use a licensed electrician for any rewiring if you are not experienced.
Brightness
Compare lumens, not watts. Tubes of the same length vary a good deal in lumens, and the figures here are the sellers’ own, not our measurements. Many listings also give an equivalent to a fluorescent tube, which is a rough comparison.
Color Temperature
Lower Kelvin numbers look warmer. 3000K is warm white, 4000K is neutral, 5000K is daylight, and 6500K is a cool white. Listings use words like cool white loosely, so check the Kelvin figure and keep one color temperature in a space.
How We Evaluate Dimmable LED tubes
We did not install or run these products. We compared manufacturer specifications and Amazon listing details, selected November 12, 2026. We could not retrieve current Amazon star ratings or rating counts for these listings, so they carry no WikiHomeLED Score, we show no star ratings, and the order is our editorial judgment of the listed specifications, not a score. We looked at the tube code, length and base, lumens, color temperature, ballast type, dimming, and any stated certifications or location ratings. We kept one listing per product family and no more than two per brand. Lumen, wattage, and color temperature figures are as published by each seller and are not our measurements; where a listing is vague or contradicts itself, we say so. Read recent customer reviews before you buy. The full method is on our How We Review page.
Frequently Asked Questions
Do all LED tubes dim?
No. Only tubes listed as dimmable should be used on a dimmer.
What do I need to dim an LED tube?
It depends on the tube. Many need a specific dimmer or driver, which the listing names.
Why does a dimmed tube flicker?
The tube and dimmer may not suit each other. Check the compatibility notes.
Are these listed prices current?
Prices are not shown here because they change often. Check the current price before you buy.
Final Verdict
Ledvance T8 LED Tube (4 ft, Type B, 5000K, Dimmable), 20 Pack is our first pick, Ledvance T8 LED Tube (4 ft, Type A+B, 5000K, Dimmable), 20 Pack follows, and Sunco Lighting T8 LED Tube (4 ft, Type B, 5000K, Dimmable), 50 Pack is third. We ordered by the strength of each listing’s stated specifications, not by ratings. Choose by the tube code, length, and base your fixture takes, the ballast type and wiring you are prepared for, the brightness and color temperature you want, and whether you need to dim.
