UL-LISTED & DLC-QUALIFIED. - BALLAST BYPASS. These tubes must be installed using the ballast bypass method. Use the instructions provided to remove the ballast from your fixtures and directly wire your new T8 tubes. Bypassing the ballast during initial tube replacement will save you both time and money as ballasts inevitably fail over time and will require replacement. Ballasts also consume electrical power and by bypassing them you will save even more on your energy bill. - SIMPLIFIED INSTALLATION. This tube can be installed with a single-ended or double-ended connection and it can install directly into your fixture’s original shunted sockets (tombstones). This eliminates the need to retrofit your fixture with non-shunted socket (single-ended installation will require non-shunted sockets/tombstones). Fast and simple installation under the functionality of your choice, this tube is designed with user experience as the defining motivator. - 5 YEAR UNLIMITED WARRANTY. This product is covered by the Parmida 5 Year Warranty, and our dedicated in-house Customer Service is always here to provide you with peace of mind. - ›See more product details ## Images ![PARMIDA 20-Pack 4FT LED T8 Ballast Bypass Type B Light Tube, 18W, UL-Listed for Single-Ended & Dual-Ended Connection, 2200lm, Clear Lens, T8 T10 T12, UL, FCC - 3000K - Image 1](https://m.media-amazon.com/images/I/61H76K1Q64L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ These are great. They require a bit of wiring modification, about five minutes of work. *by E***C on Reviewed in the United States on November 25, 2019* These are great. They require a bit of wiring modification in an existing fixture, about five minutes of work, then they plug right in. They are a lot brighter than fluorescent tubes; in some fixtures we only needed one LED tube where there had been two fluorescents. The light colour is pleasant, not too blue, not too yellow.To modify the fixture, turn off the power at the breaker, then remove the cover hiding the ballast, and cut all wires connecting to the ballast, remove it and throw it away. In a two-tube fixture, one of the ends will have two of the sockets wired in parallel, with one pair of wires going to the (now discarded) ballast. Connect these wires to the white and black building wiring. Cut the wires off the connectors at the other end. Replace the cover and that's it. The tubes have to be inserted so the end with the electronics and logo is plugged into the end with the power. They will not light up if you put them in the other way around.It is a good idea to have some extra sockets on hand, as they tend to disintegrate if they are really old. Also it is a good idea to wear gloves if the ballasts are really old, as they may have started leaking black oil... that might be PCB-based coolant in a really old ballast, and you do not want that on your skin. I was glad to get those things out of the building! ### ⭐⭐⭐⭐⭐ Using without ballasts, and using half as many *by C*** on Reviewed in the United States on March 2, 2020* I am Using these to replace the T12 bulbs where I also need new ballasts. I typically only put in 2 of these instead of the FOUR T12 bulbs in fixtures. This saves me a little time since I had to rewire a ballast anyway, so there's no additional labor to go LED. And , I won't have a ballast fail just after I put in new bulbs, so I am done.I love the color balance of these bulbs in our offices. They have a nice bright touch without being too orange or bluish. I don't know about lifespan yet. ### ⭐ Do not buy these ballast interferes with other lights *by J***N on Reviewed in the United States on May 19, 2020* I have been an electrician for 25 years. I love the new LED 4ft tubes. BUT! These 4ft tubes cost me two days in troubleshooting because they were on a shared lighting circuit with other lights. You had to have all the other lights off before you could turn the 4-foot lights in the kitchen on! Don't waste your money and especially do not waste your time so far the best brand I found AND they're dimmable are the toggle brand at Home Depot. They cost twice as much and they're worth 4 times as much. So disappointed with this products, SMH I wasted over 10 hours checking everything else except these LED bulbs. Too bad I bought them a couple months ago thinking to be a good idea to have some on hand. Now I've had them more than 30 days and cannot return them. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/155979204-parmida-20-pack-4ft-led-t8-ballast-bypass-type-b](https://www.desertcart.pl/products/155979204-parmida-20-pack-4ft-led-t8-ballast-bypass-type-b) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-09*
