Romwish 24 Inch T8 LED Tube Light, 9W(24W Equiv.), 1120LM, 5000K Daylight, Type A+B Plug & Play or Ballast Bypass, F17T8 Fluorescent Replacement, Double-Ended Power, Under Cabinet Light, 4 Pack

Bulbs are good. Bright and easy to install. Used direct connect. Took about 5 minutes per fixture to re wire.

Very bright works amazingly

Wasn’t plug and play on my 25 y/o ballasts. Simple ballast work around. simple wiring as described in the enclosed directions allows you to leave the hot running, unpowered ballast transformer in place, and easily save on electricity. I did 16 fixtures x 2 lights each. Worked great with no light failures. Good product. Thanks

I bought these for a replacement on my F20T12 garage light. They seem good quality and fit easily into the existing base. They also give off a nice bright light. I have bought replacement LEDs for several tube light fittings in the past and they all seemed to be genuine 'plug & play' - no modifications required. I didn't read the small print on these. You need to change the wiring in the light fitting to by-pass the ballast to replace an older fluorescent tube. This is fairly basic (10 mins) but should only be done by someone that has some fundamental electric skills (similar to fitting a new light fixture or ceiling fan). You should also know that once changed, you cannot go back to the old tubes without rewiring again. It is really my fault for not reading the full instructions before I purchased and seeing the 'or' in between plug & play **OR** ballast bypass. Subtle, but makes a difference.

After about two months of use, two of the four tubes melted at the connector (see attached pictures). I noticed a foul smell and turned them off in time, but this is a serious safety issue. Having half the set fail so quickly points to a major quality or design flaw.

I just completed installation of 4 tubes in my kitchen. I have under-cabinet lighting consisting of two 2ft fixtures and two 3ft fixtures. Each contains one bulb. This review is for the 2ft long bulbs. I posted a slightly different review on the 3ft bulb page. A word of caution. This manufacturer, and probably many other manufacturers, markets the same bulbs for US and foreign markets. As a result, a bulb marked as 2ft may actually be 60cm which is slightly shorter. My suggestion, prior to modifying your fixture, is to turn power off and slip the new bulb into the tombstones. If it’s not a snug fit the end prongs might not make solid contact with the tombstone(s) and fail to light. At this point it would probably be advisable to return the bulbs before making a permanent modification to your fixture. Another word of caution. LED replacement tubes only emit light on one side of the tube. Ideally you would like to install a bulb into the tombstones and twist it 90 degrees. When you do that you might find that it is not illuminating the area you wanted lit. In practice, you could get by only twisting the bulb 45 degrees in the tombstone. This is what I had to do. It’s not ideal and any vibration could conceivably cause the bulb to loosen and drop out of the tombstone. Installation involves disconnecting the fluorescent ballast. It is quick and easy but I have another warning. The bulbs ship without wire nuts. This is probably a good thing. If you don't know what a wire nut is then you should absolutely hire an electrician to do the conversion. After I converted my first fixture it took about 8 to 10 minutes to do each of the other fixtures. So, if you are paying an electrician by the hour and generously allow 10 minutes per fixture you should be able to have up to 5 fixtures modified in under one hour. I started the modification by switching off AC power at the wall switch but a safer way would be to turn off the circuit breaker. I then cut all of the ballast wires close to the ballast. I chose to remove the ballast but I could also have left the now disabled ballast in place. The fact that these bulbs have electrical connections at both ends negates the need to perform any type of modification to the tombstone(s). Single ended LED replacement bulbs would have created a problem for me. By purchasing double ended bulbs, you don't need to do an evaluation of your fixture prior to installation. The manufacturer should include stickers to apply within the fixture to warn future home owners that these are no longer standard fluorescent fixtures. I had some stickers left over from a previous project of modifying 4ft over-head fixtures using bulbs from a different manufacturer. If I didn’t have those stickers, I would have created my own warning label and taped it inside. Wiring requires you to connect the incoming black and white power wires to the tombstone(s) at opposite ends of the fixture. Since you cut the wires off at the ballast you already have red, blue, and or possibly yellow wires pre-connected to the tombstone(s). These are the wires that you will join to the black and white power wires. The tombstone(s) at one end connect to the white wire and the tombstone(s) at the other end connect to the black wire. You'll need wire nuts to accomplish this. You may need additional wire to reach each end if for example the incoming power cable is at the far end of the fixture.

Good light output and no more ballast. Still working over a year later in a kitchen fixture.

These lights came in a super heavy duty square box. Each LED light had its own box inside of that big square box. It was very well packed. I was surprised that the back of the LEDs had an aluminum backing. The top of the LEDs have a transparent filament to protect the lens until you install it. The reason I bought this 2 foot lightbulb was because it did type A and type B, which means type A can be used with a ballast or type B you remove the ballast and just hook it up direct to the power. I have a commercial building and the ballast are starting to go out on the lights in the bathrooms. I tried to find a ballast replacement. However, I couldn’t find one that would fit in the unit. The space dedicated to the ballast was so small and unique to this lighting unit that the only logical alternative was to convert it to LED Type B or replace the whole unit. Since I wanna keep the bathrooms consistent with the same lights, I decided to try this. The conversion to a type B, which means you remove the ballast and just hook it up direct to the power, was super easy. It did come with adequate instructions but a simple YouTube search will be visually better. I tested it for continuity and then connected it to an extension cord and plugged it in. Once it tested good I was able to install the unit back in bathroom. Time will tell if the LED light holds up. My experience with LEDs is that the LED bulbs don’t burn out but the electronics give up and you don’t get that 50,000 hours of life as they claim the LEDs give.

easy to install and the bright light is fantastic

Work really well.

Light is bright not that complicated to change the wiring of your fixture.

Overpriced
