Hi all,
I think this is a hot topic to many.
In the last 2 years I updated some lamps in my home. I went through a pretty expensive Philips and Osram E27 LED lamps. This because with the old CCFL, whether branded or chinese, mainly the latter, they get burned after a way shorter lifespan than the conventional halogen or incandescent. The problem is now well known and was related to the number of turn on/off cycles, air flowing and so on, achieving a long life (if the lamp was reliable) when turned on/off only one time per day in average, in a aired environment. Ok, they tried, it was a transitioning technology.
So I was quite happy about LEDs, as they are supposed to withstand more cycles. Problem is that, with the proper branded lamps, in a batch of 6 between 2 Philips and 4 Osram, only the Philips and 2 Osram survived, and the Osram were in a place in which they were not used often. The ones that died, were stopped working after 1 month, in the living room, where the switch cycles were not frequent, in a open lamp holder. Opening the lamp, I saw the LED die burned with a black spot.
Then I bought a lower brand, made in china but from a proper supplier (Beghelli) with simpler converter, which did not uses a full AC/DC, but a rectified method, therefore the LEDs were flickering a bit. The lamps are there for 2 years now, and they were 50% cheaper.
Now I need to update some spot light, with G5.3 lights, and the last bought was Philips which I was happy with. I wanted to order on Amazon again, but the price seems higher and I started to look for reviews of alternatives. Osram and Philips got fairly negative ones, while Amazon's chinese brands were pretty good evaulated. Now I believe them.
So my question is, if I want to be safe, should I continue to waste my money in LED lamps from proper manufacturers and being safe, or there are alternatives which are reliable brands? I don't like to buy from anonymous brands though, like all the chinese alternative on Amazon.
I wonder if those big companies are aware on the lack of reliability of their stuff.
Thanks for your opinions!
