Review on Enhance Cabinet Lighting with Durolux LWL7W40 F13T5 Retrofit: Direct Upgrade Solution by Sharon Smith

I bought these about a month ago and have had no problems so far.1. The length of these LED lamps is exactly the same as that of fluorescent lamps. Some other brands of retrofit LED bulbs have installation problems because the LED bulb is a few millimeters longer.2. No buzzing noises. Requires no upgrade or modifications. They are plug and play.3. Hasn't burned out yet. I'll update if they burn out fast. The last 6 packs of Ecotone tubes I bought broke within a few months. Just a waste of money buying lamps that burn out so quickly. They are VERY BRIGHT compared to 6500K fluorescent tubes. I just wasn't prepared for how bright they would be.5. Half of the bulb emits light, the other half is metal and does not emit light. But that's not a problem, you can turn it so the metal is facing the top of the cabinet.
