Although I have purchased 17 in total and the lighting is very good, 2 have broken down within a short period of two months, after only a few hours of use.

I hope the same doesn’t happen to the rest.

Zero quality! Within two months, half of the ten I bought have burned out.

It works perfectly, very good strong light! No problem with the installation in an old chandelier, 5 of these were installed together.

Two out of the eight bulbs started flickering.
It seems they do not last.
Order +50% more than you need to be sure, some turn out defective

Good product at a great price with quite strong light for its category (natural light). 4 stars because it hasn't been used enough yet for me to have an opinion on its durability over time.

In my opinion, this bulb is definitely not 4000K (white light). It is quite yellow and not as powerful as its description claims (1 bulb per 10 square meters - I would say 1.5 bulbs per 10 square meters). Other than that, for its price, I believe it is worth it as it is quite bright, the build quality is good, and for its price, you won't find anything better!

Very good for its price and for the color performance, as for the lifespan, the technician of the future will tell us that...
