Excellent price for the (half) performance.

I spend the 80-watt spotlights wall 4 points, since performance to price and order processing must be assessed as excellent. The output power is stated on the nameplate the existing CE mark would be there also invalid because a power output of 80W is in any case on the 75W, from which a PFC (Power Factor Correction) would be absolutely necessary. My power meter shows PowerMonitorPro fortunately only a power consumption of 55W (with Power Factor 54%), of which some arrive in my experience over 40W in the LEDs. Well - in China allowed to apparently strong exaggerations.
Now I do not understand why these things are so great: The LEDs only allow a temperature of 85 ° C, which is difficult to maintain in a power dissipation of about 70% of the power. The whole body is almost exclusively as a heat sink. What looks like a reflector, reflecting almost nothing, because the LEDs emit anyway mostly forward.
