I had bought about 2 years ago 100 pieces 9W Cree LED (3x3W) for the house and unfortunately had to find that about 50% of the LEDs are now already broken. The first already after 2 weeks!
This product feels the Wertigkewit to higher.
To date (after about 3 months) no LEDs has failed.
In the brightness I was skeptical at first because I have reduced from 9W to 7W. But for no reason. These are even a bit lighter than the old 9W LED's.
Brightness equivalent I think so about 40 to 50 watt halogen.
So far, I am fully convinced of the sebson 7W. From me a very strong buy recommendation!
Pay now bit by bit our house further change to sebson and toss out the other crap.
----- ----- ADDENDUM
To date, 6 months of purchase, any failures or other problems.
Now have another 20 pcs. Ordered.
