JESLED T8 T10 T12 LED 4FT Light Bulbs, 24W 3000LM, 6000K-6500K Daylight White, 4 Foot LED Fluorescent Tube Replacement, Super Bright, Dual Ended Power, Clear Cover(4-Pack)

Very nice lights, plug and play, very bright and they stay cool

These are super-bright! I replaced all 8 of my tubes and these were a HUGE difference in brightness. WOW. Suntan bright. LOL. These were real easy to install in my ballast from 1986. They look to be high-quality. Time will tell. Not heat produced from these LED's. Great value, considerably cheaper than others I saw. I will update later for lifespan.

Just plug and play, no modifications needed for our old light fixture's. No more flickering of the old light bulbs, brightened up an otherwise dark basement. They turn on instantly when the switch is hit.

I’m trying these as a direct replacement in an old style housing, they fit perfectly. They do have a slight delay in startup but better than the old lamps. Even light pattern through the refract cover, much brighter than standard light tubes. These run at a minimum of 16 hours a day so I’ll see just how long they last.

The LED replacements for regular fluorescent tubes advertise a years-long life span; I converted all my home fluorescent ceiling fixtures (21 in all) to LED-type B fixtures. The Type B fixture has only one powered end (positive & negative); the other end is a dead "tombstone". The typical average wattage use for my old lights is about 150 watts per unit. So the wattage used if all are on is 21 x 150 watts or 3150 watts of electricity. The change over to the LED tubes puts the wattage used as 21 x 18 watts or 378 watts so it is a big savings if all the tubes are on. The LED tubes are so bright that I actually only use one tube in each unit. In my change over to LED tubes, I used Hyperion LED tubes purchased from Amazon. They were installed 5 years ago and today 20 tubes are working just fine. One tube burned out (shorted out?) a month or so ago. Hyperion LED tubes are no longer available from Amazon. It is now confusing to find replacement LED tubes because some are powered from both ends of the unit just like the old fluorescent tubes. These tubes are labeled type A. Others are tubes that are powered only from one end known as type B which are harder to find. The third type is labeled type A&B. I bought one of these from Ace Hardware and it did not work in my type B unit. The JESLED unit from Amazon is labeled type A&B. The online description of the unit shows how to install it in a type B unit and the description matched how my LED units are set up. I took the chance that these tubes would work. I installed it as per the supplied diagram and it worked just fine; just like the Hyperion tubes. I could not buy just one tube from Amazon; the smallest lot available is a 4-tube set. So I now have replacements, which is a good idea anyway. The LED tubes arrive very well packaged in individual tube boxes within a very sturdy exterior carton. I highly recommend the JESLED product.
