General Electric top quality! One of the best and most reliable lamps, but unfortunately now they no longer offer any variety of products like they used to, the same goes for Sylvania, which also had the most reliable fluorescent lamps and not only those.

This version, GE Polylux XLR 18W T8 G13 in the 830 version, that is warm white 3000K and a very good color rendering index of 85 CRI and brightness of 1300-1350 lumens, efficiency 75 lumens/watt,
and it has a very nice and natural warm light compared to LEDs. LEDs produce an artificial light which I do not like, especially if it is neutral and even worse if it is cool white. Only a few LEDs have sweet and more natural light.
A good fluorescent lamp that does what it says and will do its job and more! With eyes closed, go for General Electric, American products are usually of very good quality!

If you find them, definitely prefer them if your fixture already runs fluorescent and it is not worth it at all to switch to LED, unless it does not run for many hours and is switched on and off constantly—there, the fluorescent will not last long, while the only advantage of LED over fluorescent is in such cases. But if it is not switched on and off too often, fluorescent is more worthwhile because LEDs in a few years develop problems, especially if they are cheap, you throw them away within a few years, and they develop problems with the board and some LEDs will not work, will burn out, and this happens even with very expensive and reliable LEDs. We are talking about LED street lights that cost 400 and 500€, and yet they develop such problems and in some cases cannot be fixed, a lot of cost and time, and good luck finding spare parts, it's better to buy a new one because repairing it will cost you more than replacing it with a new one, so you are trapped. But if you already have an existing fluorescent fixture, it is more worthwhile because the lamps are very cheap, costing 3€, and last 7-12 years, good quality fluorescent lamps, and maybe a starter after years which also costs nothing, half to one euro, and the ballast rarely breaks!
