20 Pack 5CCT 4FT LED T8 Ballast Bypass Type B Light Tube, UL/FCC Certified - 18W, 2300Lm, 3000K-6500K Selectable Review

I have installed 6 of these so far, two double ended with shunted tombstones, and four single ended with non-shunted tombstones. Very easy, and all six worked flawlessly. If all 20 bulb sets work, I will come back and give them 7 stars.One thing not in the instructions - when using single ended you need to put install the light with the blue collar end at powered tombstone.

Receive the Hykolity LED T8 light tubes right on time. Very well packaged no damage whatsoever. Easy to install and was able to eliminate ballast. Only had them installed for a couple of days and I want to give them time to see how they perform. Right now, performing well and I hope they do so for a long time.

Used in my work room and garage, very bright, can cut down on the amount of fixtures, easy to convert from florescent, just remove the ballast

Very happy with these. Fixture rewiring is a simple 2 minute disconnect and re connect and reomval of the old overheating ballasts. An improvement to the illumination in a garage workshop. Well packaged and boxed.

Packaged using custom formed foam; each tube has it's own nest for protection. Easily installed in a single ended configuration. Bright light that is a vast improvement over the yellowish fluorescent tubes.

30% brighter than a conventional florescent tube. Silent, no hum after bypassing ballast. Installed over 100 tubes and no defective ones. Can not speak to the longevity but as an electrician i will continue to use these for retrofitting future projects. Photo is led tubes on the right half and existing fixtures on the left half.

Several of the bulbs placed smoked initially and burned out the bulb right away. Lost several bulbs unexpectedly. The customer service department definitely cared about my opinion and was fair and prompt about getting me a partial refund for the bulbs lost.

I had no issues installing the new tubes in my existing fixtures. The tubes were well packaged, came with wiring instructions, and worked as advertised. Unlike other similar LED T8s, the fact that you can wire your fixture for these tubes in either a single end or double end ballast bypass configuration was very helpful. The tombstones must not be shunted. Great price for a great product. Highly recommend this product.

I had some bad LED bulbs that I replaced with these bulbs. They were packaged very well with no broken bulbs on arrival. They worked great with no problems.

Going from standard fluorescent bulbs to LED bulbs was not difficult. These bulbs are brighter and will save you money Thanks for attention.

When I took the time to analyze the cost of ordinary florescent bulbs vs LED bulbs, it really was a no brainer. When you consider the savings you will see on your electric bill, these bulbs will pay for themselves in no time, not to mention what you will save due to the life expectancy of LEDs vs florescents. Buying the bulk quantities also reduced the overall cost of replacing all 40 bulbs in my shop (nice). I was able to easily rewire all the fixtures in my shop to accommodate this style of…

These are great lights all the way around. One star less than five as when turning them there is a lag from the switch being triggered to the light illuminating. About half a second. I have six ceiling fixtures with twelve lights. Maybe I wired it wrong?

Amazing, bright, very white light. It is unlikely you'll need more than 2 per fixture in an office environment. There are only 2 bulbs installed in this previously 4 bulb fluorescent fixture.

Bought to replace LED Tubes about 4 years old. Old ones ran really hot and would start flickering and die. The end caps were plastic and 2 broke removing tubes from fixture. These have aluminum endcaps. They also do not have a aluminum ribbed back like old ones had, that got really hot, no blister, but not far from it.Would be 5 star, except they look warmer then tubes already there.Question if really 5000 Kelvin :-)

After installation of 16 out of 60 tubes.so far so good. Installation is quick and easy. They put out a lot of light without flicker. Packaging is nice and solid, double corrugated board with foam inserts cradling each lamp. Nothing broken out of two 20 packs and all of the lamps work so far.I will update once all of them are installed. As of right now, recommended.

I had several florescent fixtures in the house which had bulbs failing and flickering. It was very simple to remove the ballasts from the fixtures and rewire the tombstones directly. Took about 20 minutes per fixture once I figured out what I was doing. The light output is vastly improved. Literally night and day! The actual LED's are mounted on a strip inside the bulb on one side so be sure to install the bulbs so the strip is at the top against the reflector.

These replacement tubes are easy to install . Remove the ballast, connect wires together and close. Changing the temperature is a great feature . We chose 3000.

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

Lights came packaged well. Fixtures were setup for dual end power and worked right away. Brightness appears what is advertised. Great price!December 2022 Update: Bought these Sept 2020 and they are still working. They have been a good upgrade.

Great value and easy included instructions to by- pass the ballast in fluorescent fixtures. No need to get rid of fixtures or replace the ballasts any longer.
