Unacceptable and literally for the trash. I installed 2 of these bulbs side by side in an extractor hood. The bulbs were manufactured in 10/22 and purchased in February '25. Eight months after purchase, the first bulb would sometimes turn on and sometimes not. I replaced it with another brand, 6W ~500lm, and left the second Diolamp as it was. Both bulbs (new and old) produced exactly the same light intensity, you couldn't tell the difference. And yet, the Diolamp is theoretically 8W. The Diolamp illuminated less than the "730" it claims and consumed more power. Eleven months after purchase, the second Diolamp also broke, as it started flickering. At first 2-3 times and it would fix itself, but after a few days it started doing it constantly without stopping, so I removed it. Both went in the trash. Unacceptable quality. ps: Don't take into account the rating from the 150+ reviews. With a quick scroll, it's obvious that over 90% of them are from bot accounts.

I was disappointed... I put 3 in my lamp and two of them lost their brightness within 5 months... I do not recommend them

At first it seems good, but it only lasts two to three months with minimal use at night.
I had bought several from this brand in various sizes, and they all break after three months at most. So they are cheap, but in the end you end up replacing them very often. Better to get something else.

By far the most disappointing brand regarding the lifespan of the bulb. They last at most one year and then either burn out or "underperform." Over the years, different types of bulbs from the same company have been tested and all of them burned out in at most one year.
Finally, they are not that efficient in terms of lumens/watts ratio.

Well, I have a chandelier with 5 LED 7w candle warm white light bulbs in the living room. I replaced them with these (natural white light) and now I have very strong light to the point that I turn on one step in the chandelier. Now my eyes are no longer tired. VFM.

Very bright lamp. The shade is quite white and not so warm. For its price, it's okay, otherwise I wouldn't buy it again

In July, I ordered 19 bulbs. 4.5 months later, I have only 3 left as they burn out very easily. I switched brands.

Lately, I bought a lot of these specific company's light bulbs.
Most of them worked fine.
Unfortunately, several were short-circuited. I put them in the extractor fan and the circuit breaker of both the panel and the clock tripped. After removing them and resetting the breakers, I discovered that the extractor fan was no longer functioning.
You understand that in order to save 2-3 euros, I ended up being charged the cost of a new extractor fan.

I bought 3 5-watt bulbs in April 21 and November 22 one of them burned out. (I will update when the rest do the same.) They are supposed to last for 30000 hours, which is about 3 years (continuous operation). So much for this kind of economy. Instead of giving them to the power company, I give them to Diolamp. The brightness was satisfactory, hence the 3 stars.
UPDATE 18/1/23
The second one also burned out. Let's see when the third one does. I will definitely update. -1 star.

I have a six-light and a ten-light fixture in the living room. Previously, I had halogen bulbs. I installed 7w bulbs and their performance is satisfactory, providing a warm and very good lighting. The price is worth the money for this specific purchase. As for their durability, it will show in two days since I have them installed.

Multi-light with 5 diolamp bulbs at 7 watts for years, I wanted a little more light... I switched to 8 watts and noticed a good difference... I didn't expect it with just 1 watt on the bulb...

The bulbs shine perfectly, each one according to its use and space.
For example, between 5 and 7 watts, I chose the 5-watt bulbs for the kitchen.

After approximately one month of use, there has been no observed problem, the light remains "natural white," and I have not noticed any increase in power consumption.

It's great for its price. I have it in a light fixture with 5 bulbs and none of them have burned out yet, and the color is great.

Good bulb, very bright light, but one of the bulbs happened to have a loose connection on the top that creates a body in the socket, resulting in it not turning on. I believe this is purely a manufacturing error

They are very good and have strong light. If someone wants them for a chandelier with 5-6+ sockets, it is better to get bulbs with lower wattage because the light from these bulbs will be excessive.

Very good product, at a very good price. It provides very good lighting and has a long lifespan. Get it without hesitation.

Quite a good bulb for its price. My only complaint is the color of the lighting, which is a bit too green.

I ordered 10 bulbs and within 1 month, 2 of them started flickering...
Also, I put them in a fixture with other 5w LED bulbs from a different brand and I can almost certainly say that the 7w ones were darker...
