They have very good and strong light, intuitively like the 20w halogen G4, with very good consumption. However, I have been using them for less than 3 months, so durability over time is an issue. They are bulky but I believe they fit in most lights where we used to put G4 halogen, except of course for special closed-type spotlights (like the classic children's desk spotlights)

after one year of use in two rooms, living room and bedroom, half of them have burned out.
during the cleaning of the light fixtures and while I was removing the bulbs, in two of them the base detached from the transparent cover

I have had them for a year now and I am very satisfied, especially with the light they produce. Just a note, they are quite thick and may not fit in the place of incandescent bulbs

Very good. The light is a bit stronger than I would like, I used half of the bulbs I bought

Not even a month and they started burning. Additionally, they flicker for about a quarter before the light stabilizes.

First of all, it is very large in size compared to the bulbs it replaces. Secondly, and most importantly, no matter how many of these specific bulbs I tried in different sockets, they all made a barely noticeable noise, a low hum that is annoying

Very good purchase for its price. The only drawback that gave it 4 stars instead of 5 is the size of the bulb. It is huge compared to the equivalent halogen. See the attached image and you will understand.

Good light intensity, the downside is that it flickers, definitely less than the 2W ones but still
update after trying several similar bulbs, I can say that this one flickers less than the others, even if they were considerably more expensive

I bought a set of two 2w and a set of two 5w for my bathroom to see which one would be better, wanting to replace the old 20w bulbs. The 2w ones flicker and change brightness to an unbearable extent. I have commented on the corresponding product for the 5w ones.

In less than a month, two out of the five bulbs burned out, installed in an elevator of a residential building with low usage.

2 out of 3 started smoking and eventually burned out within 10 minutes of operation at 12VAC. I can't believe it just happened. This happened with the 2-watt ones, the 5-watt ones I have had for a while without any issues.

I am deducting one star because the lamp is too big in size. Therefore, if there is limited space (e.g. above a hood extractor), choose something smaller (with fewer lumens)

The brightness compared to the equivalent half-power ones does not have a difference. However, it is good and does its job, just not twice as good as the lower-power ones.

Awesome light. I approve!

Good, with the only objection being the shade which you can't really call "natural" white, rather cold, but that's also a matter of taste...

The quality is mediocre to poor. I chose them for a light fixture with 12 bulbs and the light is very dim for a 10 square meter space. Prefer higher wattage or higher lumens than 2 watts and choose transparent material in case you have crystal-type Swarovski lights (they don't shimmer with a matte bulb). They also make a slight squeaking noise that is quite annoying, which is heard loudly when it's quiet.

Quite good and high quality. I have a slight objection about its size. It would be convenient if it could be smaller (thinner diameter).

Very good and provides strong lighting with many options depending on the space. After four years, they started burning out. Used daily for at least 3-4 hours. Good product.
