JESLED 2FT T8 LED Tube Light, 12W(30W Equivalent), 1680LM, 6000K, Ballast Bypass, 24 Inch F17T8 Fluorescent Bulb Replacement, Dual Ended, 24” Lighting Tube Fixture (4-Pack)

This was my experience replacing the light tube in my 24" 20Watt aquarium fluorescent light. I chose the 6000K color temperature of this replacement to simulate the full sunlight spectrum. Unlike other "daylight" lamps, this particular light is not excessively blue or purplish in color. I also expected the brightness level to be higher than that of aquarium specific lamps. My aquarium light hood was originally manufactured with a ballast and a starter. This was a common method of wiring these fluorescent light hoods. The inclusion of an automatic starter device, instead of the push-to-light switch, allowed the use of a timer to control the lights. I had already replaced the FL tube with an LED type. The original replacement unit did not require that the ballast be removed, just the starter. This time around, I bit the bullet and decided to try this type of LED replacement tube. There are three basic types of LED replacement tubes. Besides the ones that do not require the removal of the ballast, there two types that involve a wiring modification. One kind of replacement LED lamp is powered from just the two pins on one end of the tube. This may require the replacement of the actual sockets on the fixture, and I felt this would involve additional work and wiring. I also did not like that the light tube has to then be inserted in a specific orientation for it to work. The other type is what it is represented here. The lamp is powered by running one wire from the AC to each socket. Removing the ballast and the starter from the circuit was a rather simple modification. The existing switch and socket wiring was long enough to connect to each of the lamp and no additional parts were required. I went ahead and also removed the socket for the original starter and, since the fixture is subject to moisture, I sealed all of the access and mounting holes leading to the exterior. The light was never meant to be waterproof, but I didn't want any water accidentally spilled on it, to have a direct path to the circuitry inside. Ok so, how did it work out? The tube lit right up without any flickering or vibration (hum?) noise. My aquarium is 24" inches high. The light is bright enough to properly illuminate the substrate. It works very well for my application. I would certainly recommend it for this or any other application where you can make the necessary modifications to the fixture.

Simple to install. Love the light they give off.

Not all fluorescent fixtures easily adapt to LED bulbs. We had 4 large ceiling lights in a living room with 10 ft ceilings. We changed our old fluorescent bulbs for LED's, reassembled the fixture, and it looked great! The ballast had been disconnected in that one. We found that the old ballasts need to be disconnected for the other three lights. The bulbs work great, but we need to modify the fixtures.

No flickering and super bright

These worked pretty well but I had 1 defective light in the 4pack I received. I tried to use the plug and play but it seemed the ballast caused overheating. (Not with the defective one, that happened at a different ballast.) After the overheating event with the plug and play option, I opted to do the by pass method which seems to be working well. I plan to buy another 4 pack even with the 1 detective I had because overall I like the style and I want the consistency in all of the install locations I have. Buying a new LED with ballast mount costs about $30 at HD and with this I have some spares if needed. I had a friend test the bad one's connections and was told that there was a defective LED somewhere in the series so fixing it wouldn't be much of an option.

Does not work reliably as a ballast bypass tube. In order to work, the ballast had to be removed and bypassed by changing the wiring in my light fixture. This defeats the purpose of buing a Type A or A/B tube. I'd recommend choosing a reliable brand such as Phillips or GE.

good bright lite , renovated old fluorescent fixture

Good ans easy replacement for aquarium light
