My first attempts were good 5 years ago only expensive and the results are quite sobering. But now the price is right and the quality, you should but a little with Lumen, Kelvin and radiation grappled so as not to be disappointed. Some LED bulbs I use the way for 2 years, others for a few months. Failures I had not yet.
So after 2 months is a of 2en broken ... 12 pcs Philips LED -. Lamps with 11 Watt, which I bought at the same time and have largely given away all work without complaint. The light is even a tad better. This I bought at 18.50 with another provider.
Addendum after 4 months:
Since I had to reclaim a total of 3 lamps with this provider, but only a specific type. Have I done now. But I refused to return at my expense because I think that would be disproportionate to the value of the lamps. After a somewhat tedious back and forth you content with photos, which is a bit absurd in a lamp with a total failure, with no visible damage. Anyway, I got today 3 new lamps, plus a gift. But since I have purchased from this manufacturer but min. 30 pieces, which is now very satisfactory especially as the failure occurred immediately and the rest worked perfectly since 4-5 months. Therefore now but again 4 stars.
Addendum after 11 months:
Both of them still function properly.
Addendum after 18 months:
Another less, but as I got one for free, so go 2. The exchange rate was still but at 100%. But I'll stay with the 4 stars, because of the friendly CONVERSIONS.
