20-Pack 4FT LED T8 Ballast Bypass Tubes, 18W, 2400Lm, 5000K, Frosted Lens, UL Listed For Single-Ended & Dual-Ended Connection In T8 T10 T12 Tube Lights With G13 Base, 120-277V Review

These lights work as advertised. Only reason for not getting 5 stars is that they are NOT "instant on" as mentioned in the product description. My definition of "instant on" is it turns on the instant you flip the switch. These lights have a half second delay after throwing the switch. This is actually mentioned further down in the product description but this is clearly misinformation. "Instant on" is "instant on", not a half second later. It's amazing how noticeable the delay is. Annoying but

We purchased these bulbs to replace our older bulbs. They were easy to install and we hope to see saving on our electric bill

I installed 2 cases of these in my shop I no longer have to wait for the cold florescent lights to warm up in the winter and they should pay for themselves this year. They are also a lot brighter then the old lights.

These are the ones to buy. No ballast is needed. Looks like a great product but my delivery was damaged by the shipping company. (Not Ebay) I returned them and quickly received the credit.

I had flouresents all over the place. Removed ballasts and used sockets with LEDs. Garage is brighter than it's ever been, patio, kitchen and dining room are BRIGHT ! Bestlighting ever !

Lights work great, the reason for 3 stars is when lights are on they interfere with radio reception and cause static on the radio! which means no music in the shop.

Had no issues, removed ballast wired hot and neutral on same side with blue tag. Works great nice and bright. Thanks for attention.

Ease of installation was a plus. They weren’t as bright as I was expecting but all in all they’re a good value. They have not been installed long enough to tell if there is a energy difference yet.

When they work, they work well. I installed 16 tubes a few months ago. Removing the old tube and ballasts took about 10 minutes per fixture. The lights are very quiet now that the existing noisy ballasts have been removed. My only complaint is that within a few days I had one tube that began to flicker, so I replaced it. After a few weeks I had another tube fail completely (won’t light up). Two tubes out of 16 (12.5% failure rate) is a somewhat high for new bulbs.

I was able to update our fluorescent fixtures with worn out ballasts. Cost of these tubes was a cost effective way rather than trying to use new fluorescent tubes much less replacing ballasts. These tubare as bright if not brighter than original fluorescent fixtures.es

I have the 5000k tubes and find them excellent in my shop. The packaging was superior. The price per tube was a good deal. Can be difficult to find replacement tubes if needed.

Very bright easy to install but instructions could be a little more descriptive for people that have never done it before

I have bought 4 boxes of these bulbs. I needed 60 of these lamps in my garage. I have not had a single failure. Great brightness and I love these lamps. Came nicely packaged.
