In general, the lenses of good external quality, sit tightly on the LED, neat. But the angles do not match the stated! There is a formula for determining the focusing angle of optical lenses, which says the following: the radius of the light spot multiplied by the distance is equal to half of the angle of tangens. As a result of my calculation it turned out that the seller's lenses have not 30 degrees, but 15 degrees. Those lenses, which are declared as 45 and 60 degrees, are in fact little different from each other and are about 30 degrees. The light spot from the distance of 1 meter by 30 degree lens was only 26 cm, and should be at this degree 54 cm! Consider this when choosing! Here is the video with my testing and calculation: https://youtu (Point) be/fln8-xwkayg used the led purchased here when testing: http://ali (Point) onl/yjj

The seller sent the goods very quickly. At 45 degrees it seems, but the backlight is not very uniform, sit on the diodes to the star, but stuck in the wires soldered to the star, had to cut holes under the wiring. I wanted 60 degrees, but forgot to specify, and the next day the seller has already sent, why it was not possible to make the choice of the angle right on the product page is not clear.

The seller at the registration confused me and confused himself, eventually sent the wrong lenses. I tried to prove that it was not him and I, the result of the dispute in my favor and a partial refund. When making out, be careful when choosing a nomenclature.

It's all crazy. But the lenses are bad to keep on the LEDs. There is a place of fixing a little bit to melt with a soldering iron. It took one star off. This is my second order. There were no problems with the first.
