About This Product

Feit Electric's 18-Watt Ballast Bypass (Type B) Non-Dimmable Linear LED Tubes replace T8 or T12 fluorescent and LED tubes. They require direct wiring by bypassing the existing ballast. This added installation step enables efficient operation and less maintenance over time. Each Linear LED light produces 1800 Lumens, emitting the same light output level as traditional fluorescent linear lights, while using less energy. These versatile 4000K Cool White lights provide clean, neutral white light for both living and workspaces. Use them for multi-purpose lighting or task lighting wherever it is important to feel refreshed and ready to get things done. An ideal choice for most fluorescent linear tube replacement applications, use them in offices, garages, workspaces, warehouses and more. T48/840/B/LED/10 lights turn on instantly, offering flicker-free full illumination with no warmup time compared to fluorescent tubes. They are mercury-free, with a shatter-resistant coating for safe and easy disposal. Each high-quality bulb offers accurate color-rendering, for more vibrant, true-to-life colors. Lower heat emission extends the life of the tube and ends do not turn black or burn with age. Enjoy lower maintenance costs compared to traditional fluorescent circline lights. The estimated energy cost is only $2.17 per year. Switch to Type A LED linear lights for your space and get up to 50,000-hours of superior light. That's 45.7-years based on 3-hours of daily use.

Q:what is type b ballast by-pass (in reference to led lightbulbs)?
by|Dec 4, 2023
2 Answers
Answer This Question

A:  Thank you for your question, this bulb is a T8 & T12 bulb, direct wiring to eliminate the need for ballast.

by|Dec 4, 2023

    A:  As the product expert said, there is no need for a ballast with bypass bulbs. I prefer these types, since you will lose efficiency if you keep the ballast, and there's a greater chance of failure in the future. You will need to rewire your fixture though.

      Q:I have unshunted tombstones. Do I need to run a jumper from the 2nd slot to the 3rd slot to get power to the other side of the tombstone. To my understanding that's how it works but hard to find any documention.

      Answer This Question

      A:  Yes. These bulbs require power on both pins on one side and neutral on both pins on the other side. I had to use jumpers with the tombstones in my fixtures. After doing a few dozen you get pretty fast at it:)

              I updated to FEIT LED 5000k lighting is great
              I removed AC power, removed the plastic covers, removed the metal safety cover, clipped off wires at the ballast, removed the ballast. I connected the yellow wires to the Neutral wire and connected the red and blue wires to the Hot Black wire. Neutral wire goes on one end of the tube, the other end of the tube has the hot wire, normally black. I ran out of led tubes therefore two fixtures have a single led tube in each fixture. Works great! Instant on light is great! 5000k is Daylight.

                4000K bulbs are closer to 3500K
                We have a whole building and we have standardized on 4000 K for everything. I replaced the guts and lamps and three fixtures with these, and they stand out as much warmer color. All the rest of the tubes in that room are fluorescent, 4000 K, 840s, major brand. These are definitely warm looking by comparison. . Usually 4000 K looks white. As with most of these LED tubes, the last 3 inches or so of each tube is plastic, and not lit. So you can always see the LED tubes through the lens as different than fluorescent. But I don't think that's a dealbreaker. Also, they don't diffuse as well as fluorescent. When you take a photo and debit down, these are thinner tubes than fluorescent because the florescence spread the light better. But I'm thinking that's standard for LED Tubes, and I'm not surprised. And again, that's not a dealbreaker. If I could find ones that look like 4000 K, I'd buy a bunch. PS, I am a retired electrician of 35 years. PPS in the photo, look at the ceiling color to see the effect.

                  LED conversion
                  I have been looking for a product like this to replace my aging flourescent tubes. The light is a soft white and makes no buzzing like my old ones. They come securely packed for safe shipping. You will need someone with electrical competence to safely convert the wiring. There are markings on the tubes to indicate which end connects to the live and which to the neutral bracket. The instructions in the box are clear and I did it in 5 minutes. This completes my household conversion to LED!

                  LED tube light bulb
                  Feit Electric 18-Watt 4 ft. T8 G13 Type B Ballast Bypass LED Linear Light Bulb Packaged as a 10 pack of LED replacement lights for your old style florescent light bulbs. These lights bring welcome improvements over the old style light bulbs they replace. No longer will you have to put up with the light flickering when its in a cool environment. Lights come on instantly, and no more hum coming from the ballast. You do need to do a small easy to do, one time modification to your light housing the first time you want to use these. The included instruction tell you how to do this. Basically, you will be bypassing that ballast, and your lights will be wired directly from then on. These lights will provide the same amount of light as your old bulbs, while using even less energy to light them. I will be replacing my old style florescent lights with these in my garage in the coming weeks. Looking forward to all the benefits these lights provide.

                  Great option. no more balasts..
                  just installed some of "Feit Electric 18-Watt 4 ft. T8 G13 Type B Ballast Bypass LED Linear Light Bulb, Cool White 4100K (10-Pack)" NO more Balasts!! Installation is the right word since some of the wiring needs to be updated by removing the balasts. It can seem intimidating at 1st but it is quick & simple. after that make use to place the warning stickers in sight. not sure how a fluorescent bulb would handle full voltage.. I went from daylight to cool white.

                  Flicker no more!
                  Aren’t you tired of flickering LED lights? Aren’t you tired of turning them on and waiting for them to warm up before they come on to full brightness? I know I was! These replacement LED bulbs are absolutely fantastic. They are a bit thinner than the old fashioned fluorescent bulbs but don’t worry at all. They throw excellent light without any of that pesky flickering or brown out problems of the old fluorescent bulbs. At five dollars a bulb when you buy in bulk this is a great deal! Check out the photos. You won’t be disappointed with this product.

                  Feit Electric 18 Watt T8/T12 Ballast Bypass LED Tube Light Cool White 4000K ( 10 Pack )
                  Fantastic 18 Watt Led T/8 light bulbs 4000K ( cool white ) 10 pack to replace the old flourescent bulbs and remove ballasts. 4 foot long to fit into your existing light fixture. Just eliminate the old ballast and switch them to these energy saving LED bulbs ( instructions included ) These can be used in offices,garage, warehouse, basement , just about everywhere you have the old flourescent bulbs. Line votage for these are between 120 volt to 277 volt. Uses 43% less electricity to operate these as opposed to the older flourescent bulbs and puts out much more light and will work in colder areas. These are NOT DIMMABLE. These bulbs are mercury free and shatter proof. Flicker free, instant on for full brightness. Can be used for commercial and residential indoor use. I replaced a bunch of old flourescent lights in my double car gargae , it's not heated and up here in the Northeast we have cold weather and the colder it got outside my flourescent bulbs would hardly come on or not come on at all. These LED tubes will come on when it's cold. Very easy to eliminate ballast and insert these into the lamp holders that your older flouresecnt fixture has, nothing special to buy. Installation is a snap once you remove the ballast. Puts out more light at a faction of the cost and will lasts years . I highly recommend these LED bulbs, the price is about $6.00 per bulb if you buy the 10 pack.

                  Works great ! – with some minor rewiring
                  This is a great product, but you have to do some minor rewiring to remove the ballast from the circuit. Depending upon the fixture and your experience level with wiring this can either be easy or not quite so easy. The instructions say what is needed is to put the Neutral (-) negative white wire on one end of the bulb (sockets) and the Hot (+) positive black with on the other end of the bulb (sockets). In our case the wires inside the unit were 18 gauge White, Black, Red, Yellow, Blue and Green (ground). We spliced the Black wire to Blue and Red on one end, and the White wire to the Blue and Yellow wires on the other end. We used 2 new yellow wire nuts to complete the circuits. We left the Green (ground) as is. We also removed the ballast, to confirm that the unit is now LED and not florescent. Various manufacturers use various colors so the above sequence may not work for your particular light. But the end result needs to be Neutral (-) on one end, and Hot (+) on the other end, for both bulbs. The Green ground wire stays attached the fixture. If you don’t understand this call a buddy or do some research on the Web. As usual there are some really good videos on you tube. One we like is EZ LED T8 Fluorescent 2-Tube light Conversion in 5 minutes or less by Total Bulk Lighting. Install bulbs with the gray stripe up if you want a more pleasant lighting display below. The color is 4000K which is White. We really like the fact that we can just change the bulbs and not have to replace the fixture.
