Delivery 2 weeks, good.
The crystals themselves are large, on a small current glow all evenly, checked the whole batch. One disassembled, the crystals really more than 1mm.
Of the minuses-the substrate is not copper, but brass. In the description of large red letters it is written that pure copper. Deception! And as you know, even the best varieties of brass have a thermal conductivity of 2 times lower than aluminum, which is about twice worse in thermal conductivity than copper. It was very sad, of course.
In addition, the substrate itself is uneven, it required grinding. Keep in mind, when tightening bolts in the corners of the middle of the led rises, it is visible even on the eye, there is no contact in the center, the paste will not help. Clamped from the sides.

Unfortunately, the second batch of poor quality diodes. If you apply for them low voltage-burn 1-2 segments in full brightness (out of 9). At full power, they do not live for a long time-one, two months. 3 years ago, the claims were not in quality, now one is not.

With a lower voltage, as already written in the previous review, only a small part of the segments burns. Selectively checked three chips-one defective, with proper nutrition only 6 out of 9 segments burns.
