Sunco 10 Pack 4 Foot T8 LED Tube Light Bulbs, 18W, 5000K, Ballast Bypass

bought these to replace my old fluorescent light bulbs. you do need to do a ballast bypass. you can’t just install these with the ballast still installed in the fixture. i enjoyed the brightness and overall quality of these

This specific bulb eliminates the flourecent ballast which is great but you will need basic electrical knowledge and tools. You will need A wire cutter / stripper, some pliers and maybe a screwdriver for opening the light fixture and a few of your favorite type wire splices. Don't forget to turn the power off before starting. Start to finish was about 10 minutes for a 4 tube fixture and what a difference! Ordered a 2nd case of ten. Relamping my detached 2 bay garage which will take 26 LED tubes. Hope to buy another case next month to finish the job. Great Product. Reasonable price. I bought the first case to relamp my master walkin closet and the laundry room and the light over the lavatory sink They have all been working for at least 2 years with no problem. I might change my connected garage over to two 8 foot, four tube fixtures from the current 2 fixtures with three 60 watt equivalent LED screw in bulbs. You will love the difference so much it will be hard to stop. Sunco makes great retrofit puck type LED lights too. Bathroom, vanities and ketchen - fantastic! Good luck with your lighting upgrades!

Product is great. Came with 2broken tubes.

I removed my florescent light tubes and plugged these LEDs in and they worked, sort of. In a two tube fixture, one LED was noticeably brighter than the other. Then they flickered and had trouble turning on when I flipped the switch. Not good... So I figured the ballast from the florescent fixture might be the problem. Sure enough, bypassing the ballast did the trick. The LEDs are bright, come right on and don't flicker. However, bypassing the ballast on 5 fixtures is no small job, especially working overhead with 71 year old shoulders. They could have supplied better instructions for boneheads like me, the one line diagram on the box left some questions, but in the end I figured it out. I now have a much brighter workshop.

Bright, Efficient Upgrade for Fluorescent Replacements I picked up this 10-pack of Sunco T8 LED 4-foot bulbs to replace older fluorescent tubes in my garage and workshop, and the difference is night and day. At 5000K, the light is crisp and daylight-balanced, which really helps with visibility for detailed tasks. The frosted lens diffuses the light well, so there’s no harsh glare, just even illumination across the room. Installation requires a ballast bypass since these are single-ended power Type B tubes. That means a little wiring work is necessary, but once done, they’re very straightforward to pop in. I actually prefer this design because you eliminate the ballast as a potential failure point down the line, which should make the fixtures more reliable long-term. Just be careful to follow the instructions closely and make sure the fixture is wired correctly—especially if you’re not familiar with electrical work. Each tube puts out 2200 lumens at only 18 watts, which is a big efficiency gain compared to the 32-watt fluorescent tubes I replaced. They fire up instantly with no flicker, and there’s zero hum (a big improvement over my old buzzing fluorescents). The build quality feels solid, and the frosted coating helps hide the LEDs for a cleaner look. If you have a lot of fixtures to upgrade, the 10-pack is a great value. These also carry UL certification, which gave me peace of mind about safety. Bottom line: A worthwhile upgrade for anyone wanting brighter, flicker-free lighting with long-term energy savings. Just be ready for the initial rewiring, after which they perform flawlessly.

3 of 12 completely burned out and the rest have filling chips on 25% of the length. I have them on a motion sensor in the garage so they average about 30 minutes a day and they only lasted 2 years.

I used these tubes as LED replacements for ballast-type fixtures, since I had several with bad bulbs/ballasts. The first shipment of ten bulbs arrived in a box that was on it's last leg and had obviously been handled carelessly during it's journey. The box had been dropped on one end, breaking the mounting pins and rendering 4 of 10 bulbs unusable. Reported to Amazon and they sent out another shipment that took 3 days. Directions are included on how to convert the old fixtures to LED, removing the ballast in the process. These LED bulbs use power at only one end, and the fixture wires on the other end are cut off and removed from the tombstones, which I reused. Those tombstones without wiring are responsible for securing one end of the bulb and nothing else. I installed new non shunted tombstones for the powered ends and connected them in a parallel fashion, which made the wiring simple and with fewer crude connections. The only wire nuts used were for connecting the main power and neutral wires from the switch, and the bare copper wire for the ground was left undisturbed. There are several YouTube videos on how to do this. The lights are bright and don't hum, and they are plastic - not glass. Even though I have 3 fixtures that hold four bulbs, two bulbs is enough light and is as bright as four fluorescent bulbs.. It's been a couple of months and they're holding up well. Would definitely buy again. 7/01/2022 - UPDATE - So far, I have not experienced any failures or malfunctions involving these T-8 LED replacements and it's been two years. There are several fixtures in the shop that are left on for 24 hrs, and even these have performed really well and do not get hot. To alter a fluorescent fixture to be able to use these bulbs is just a matter of knowing how to follow directions. With these bulbs, the power is supplied only on one end and the ballast is not used. Complete, easy-to-follow instructions are included within each individual bulb. I've been very pleased with these bulbs.

Was replacing fluorescent light with those LED and they worked great, bright daylight feel. No complain would recommend.

Just received and installed eight of ten in a couple of hours. Very pleased with the results. Being frosted gives nice even but bright light. Some electrical savvy required to bypass ballast for best and most efficient results. Used some of the review tips on Amazon.com but basically all connections at one end can be line and the other end is neutral.

Installed these in my garage without ballasts. Bright white light, even brighter than a brand new fixture that was whiter than my old tubes. Totally satisfied. Only time will tell if they last long...

Love these. They work with the ballast left in, but too many on the same run and weird things happen. pull the ballasts and they work great. I've bought about 40of these now.

These lights met my expectations. They seem to be as bright as the slightly higher wattage bulbs they replaced. There is no delay when turning them on. No buzzing or flickering either, likely due to removing the ballasts prior to ordering these. Would have given 5 stars had one of the lights not been damaged. Not a shipping issue as the packaging was intact, no signs of bumping … It works, so I didn't return it, or seek a replacement for it.

came earlier than expected much better light than regular floresants bulbs
