I give 4 stars because it is not completely natural white and has a slight warm tint, but it is not bothersome and is easy on the eyes.

Fluorescent lamps contain fluorescent and other chemicals that emit light with the right voltage. Natural light due to a chemical reaction and not artificial from a semiconductor with a direct energy gap like LEDs. Personally, I find the white light in the circular fluorescent of the kitchen very convenient, as well as in the fluorescent of the office. The daylight of a 36w fluorescent, for example, is much more natural and better than a 6,500K LED, which has an almost blue hue and is tiring. I believe that fluorescent in Daylight has the best light. Of course, these are tastes, and everyone does what suits them in their home. Anyway, I replace the regular bulbs in the kitchen and bathroom with fluorescent ones. I can't find a hue in LED. All colors look artificial and fake.

I will write my review as well.. the bulb is excellent in natural (4000K) with strong, proper lighting.. it replaced a factory LED strip with a transformer, in a bathroom mirror and also DOES NOT require a transformer or starter.. it connects directly to 220V.

Six months without a drop in light intensity (measured with a photometer). It is still early to compare its lifespan with a fluorescent one that it replaced.
