    Hello,

    I have been living on my own for 2 years and I do nothing but constantly change light bulbs. Generally, I have only led and I try to buy the "better" ones, i.e. philips and osram, but still every few weeks it rains, despite the guarantee of 10,000 working hours, etc. I am willing to pay more for the bulbs, as long as they only shine for a few years as the manufacturer says especially since I often sit in the dark and the incandescent lights don't work 24/7.

    Probably the type of bulbs, power and color does not matter, but just in case. At home I use:

    GU10
    E27
    MR16
    and G4 (although I only mentioned this one once, and the problem with them is that the ceiling burns to me ;) ).

    Power 500-1200lm
    The color ranges from white to warm, I don't remember exactly now, but rather in the range of 2700 - 4600k, nothing to the extreme.

    First of all, you should consider why you get burned every few weeks :-) it shouldn't be like that

    How are these lamps powered, with what voltage?

    new LED bulbs are so powerful that they overheat and fall down regardless of the manufacturer. Whether cheap "Chinese" or expensive "company" one czort. One diode usually burns out and the bulb goes out, I talked to one of the sellers and he said that sometimes 10% of light bulbs are complained about ... I have a similar problem at home. It's just the market trend - bulbs MUST break in order for business to move, and those that break before the warranty expires are "costs" and are included in the price. :)

    Not one every few weeks, but I have already replaced each of them twice, so practically none of them worked more than a year.

    I have four of them (two are still in the box, because they were packed in three) and they have been shining for over four years, so I can recommend them. If my memory serves me correctly, I bought at Castorama and I think I paid 40 PLN for such a box.

    If you have ALREADY insisted on these LEDs and they are under warranty, give them back / replace them in the store and what's the problem.

    What should I insist on? I know I should, but I always lose receipts, I don't have space for packaging, etc. Anyway, it still doesn't bother me, I don't want to exchange, just buy something decent that you don't have to fly with.

    Once again, I will repeat the universal truth that most LED lamps end prematurely due to too high operating temperature.
    High temperature, on the other hand, is the result of:
    - poor heat dissipation from the LED structure (which equals a cheesy product)
    - poor heat dissipation resulting from the operation of the lamp in unfavorable conditions (we are talking about assembly in violation of logic)
    And so: whatever brand you buy, you will lead to premature wear and tear if, for example, the light source is mounted in a tight fitting with a small volume and made of heat-insulating material, e.g. plastic. The same applies to the installation of light sources in ceiling luminaires, where the space between the ceiling and the built-in furniture is tight and / or filled with insulating material (e.g. mineral wool).
    It can be assumed that a well-made LED lamp is able to dissipate the amount of heat that arises during its operation in an effective way in the open air at room temperature, provided that the power of the source does not exceed 3-4W for GU10 / MR16 lamps and 8-9W for lamps with an E27 base with the volume of a classic bulb. These are not laboratory data, but observational conclusions. The efficiency of an average LED source is about 50%, i.e. half of the power indicated on the packaging is converted into heat. And I guarantee you that in a closed hand you will not keep the resistor on which the 2W power is emitted.
    So the conclusion is simple - it is better to use more light sources of less power than less of a larger one.
    Another fact is that colder-colored sources are more efficient than warm-colored ones.
    It is worth choosing sources that have a greater number of structures at a given power.
    Well, and what may seem funny, go to the weight store. Unfortunately, the times have come that the producers are fucking us at every step. Heavy led lamp = a lot of aluminum. The more ribbed the better. Batteries are also heavier, the better. They look at me as if I was crazy, when I buy a cable I touch it first with a magnet or sometimes not a steel one, and when I buy it "by meter" I peel a piece and burn the vein (because they are made of glass or synthetic copper-plated fibers).
    To sum up: a heavy, low-power lamp with lots of structures will last the longest.

    You are buying the less powerful ones. And they are supposed to work. As for the GU 10, the most durable are those with a power of 5-7W, while 9W is worse. Those with 11W are already bad. Make it a long warranty and replace it. A lot also depends on the party. Of course, from heat dissipation through the luminaire itself.
    I have different durability, such as a candle 18 hours a day and they have been operating for 6 years. But these are old constructions with only 3W and a low light beam. And others vary. From 3 months to 3 years. Depends on how you hit.

    Note that in such a bulb there are approx. 60 LEDs, often 3 LEDs packed in "one LED". They are all connected in series. It is enough that one led changes the parameters => higher voltage drop + the same current and it is on. Of course, the reason may be the mentioned temperature, but also technological differences that occur over time (uneven wear)

Topic summary

The discussion revolves around the frequent failure of LED bulbs, particularly from brands like Philips and Osram, used in various models such as GU10, E27, MR16, and G4. Users report replacing bulbs multiple times within a year despite claims of long lifespans (10,000 hours). Common issues include overheating due to poor heat dissipation, improper installation in tight spaces, and technological variances in LED manufacturing. Recommendations include opting for lower wattage bulbs (5-7W for GU10) and ensuring proper ventilation to enhance longevity. Users are encouraged to utilize warranties for replacements and consider the conditions under which the bulbs are installed.
