About This Product

Toggled direct-wire/Type B LED tubes (2-pack; 5000K/Daylight) are designed to replace T8 and T12 fluorescent tubes. Dimmable with compatible switches, UL Classified, and FCC compliant. Energy efficient. Only 16-Watts of energy delivers 2,000 lumens output. Long-life rated for 50,000 hours with a lifetime residential warranty. All Toggled LED tubes eliminate ballast systems, reduce facility lighting costs, enhance the quality of light and are mercury free. Installation requires rewiring around ballast systems to non-shunted lamp holders.

Questions & Answers

Q:If the fixture is plugged into a voice controlled outlet can the tubes still be dimmed?
by|Apr 10, 2024
1 Answer
Answer This Question

A:  We have not tested our lamps with any plug-in/outlet dimmers to know if our lamps would be compatible. Typically, outlet dimmers lack a ground connection which means you will need to ground your fixtures separately to ensure they may be safely operated. We have a compatible dimmer list available on our website of the dimmer switches that we recommend with our lamps. We've provided the link below for review. https://toggled.com/resources/product-support/compatible-dimmers/ We would be happy to speak to you in more detail about any installation questions you may have. Please feel free to contact us directly at 1-844-toggled or at support@toggled.com.

    Q:Does this emit any EMF interference ? Do you have a battery back up for these lights ? I have some 2' with battery backup I would like to replace also. What is the brightest bulb you sell ?
    by|Apr 6, 2024
    1 Answer
    Answer This Question

    A:  Toggled tubes have electronics inside the tube and like most electronics, it will produce some amount of radio noise. Our tubes have been tested and complies with FCC Part 15 Class B. We do not have a battery backup for our tubes. Our LED replacements will not work with an existing battery backup ballast. You can use a micro inverter battery backup that's designed to supply our tubes with AC voltage in the event of a power outage if needed. We've included a link below to one of the inverters that we typically recommend. https://www.signify.com/en-us/brands/bodine/products/inverters/elis20 We sell our Ultra-High Output tubes in 2ft and 4ft lengths. These are the brightest tubes we offer. The 2ft tubes have 2000 lumens each. The 4ft tubes have 4000 lumens. If you need assistance selecting the best tube for your application, please let us know. We can be reached at 1-844-Toggled or at support@toggled.com.

      A:  Toggled D-series tubes are dimmable when using a compatible dimmer switch. A link to our recommended dimmer list is below for your review. Please refer to the first chart on the dimmer list for model D416-40321. https://toggled.com/resources/product-support/compatible-dimmers/ If you have any questions, please contact us directly at 1-844-Toggled or at support@toggled.com.

        Q:I have confirmed that my fixtures have non shunted lamp holders. They are wired on one end. Can I add wires on the other end and add more fixtures to the same circuit? How many can I put one a 120V 20 amp circuit?
        by|Dec 24, 2023
        1 Answer
        Answer This Question

        A:  Since your current lampholders are already non-shunted, you can leave them in place for the conversion process. Since Toggled tubes are single-ended power only, you’re only wiring one side of the fixture. The other end of the fixture is non-powered. It’s for support purposes only. You can have multiple fixtures on the same circuit. For example, if you’re using a strip fixture, they typically have knockouts you can use to connect them together. You could use the knockouts to hardwire the fixtures together using conduit, flexible conduit, or NM wire with the appropriate strain reliefs. If we can assist with the installation process, please contact us directly at 1-844-toggled or at support@toggled.com. Each 2ft tube has 8 watts. If you’re using 120V, that’s about .066A each. With that said, you could put over 200 tubes on a 20A breaker.

          Easy fix for outdated ballast
          Was pretty easy to install in garage and works as expected. Got rid of old ballast. Comes with everything needed for smooth installation

            My wife loves it!
            I had to bypass the ballast, but once I got them installed, it was working very well. My wife appreciates the brighter light in the kitchen.

            Easy after the first time. Read for photo context.
            I retrofitted my kitchen with 4500k bulbs in a single morning, never having done this before. I decided to get 6500k for the garage and finished hours before sunset. I'll leave photos for comparison. I won't blame the manufacture for me thinking 6500k means "more bright" than 4500k, but I realized it just has to do with color. I wish I got 4500k for the garage. 6500k is way too cold for comfort.

              Easy after the first fixture
              Replaced 2 fixtures in the kitchen and one in the hallway. After removing the wire cover and figuring out what the heck I was looking at, everything became clear and easy. The 4-lamp fixture had 2 balasts wired in series. The instructions were to remove the balasts entirely because the bulbs themselves have regulators installed. So I wired one side in paralell, clipped the wires on the other side installed the bulbs and now everything works. I also did my garage but with 6500k bulbs.

                You can save $$$.
                Bypassing the ballast in a fluorescent light allows you to eliminate the issues of the ballast.

                  Came with a bad led
                  After installing the lights one of the LEDs didn’t work. Kinda frustrating to have this issue with a LED. After returning and getting a replacement they worked fine.

                    Too easy to upgrade.
                    This kit came with everything you need to update old lights. Easy to do, even has videos you can watch before tackling this project. I'm happy I finally have a QUIET working light.

                      A bit too $, but good anyway
                      Good color white, easy to disassemble, not too brittle, nice wide dispersion, +1 for single-ended, dimming works smoothly. A bit more than I wanted to pay per tube, but close enough I'm tempted to buy more.

                        replaced lamps and transformers with LED tube
                        I converted 4 fixtures that originally had 4ea 4 ft lamps. I installed 2 LED lamps 6500K lights in each and they provide very good light in the shop. Instant full brightness on and not all the annoying hum. The manual needs improving in the wiring diagram
