Wang Hank started a discussion with the test results he published on Linkedin. According to his statement, he tested the LEDVANCE (OSRAM) brand LED floodlight at -14°C for 2 days and at 85°C for 2 days. He stated that the LEDs were damaged as a result of this test, and the color temperature shifted from 6000K to 8750K.

The first question that came to this post was about whether the product is real or a counterfeit. Wang Hank said to this question, “I would like to say it’s fake, but it looks 95% real. EMC/EMI tests look great, I don’t think so much investment can be made in quality in a counterfeit product. But it’s still possible.” said.
It is claimed that OSRAM DURIS® E 2835 LEDs are used inside the LED floodlight. On the datasheet of this LED, the operating temperature range is shown as -40°C – 85°C. Hank also states in his test that it remained within this temperature range.
Hank plans to get some benchmark data by testing top brand examples.
Steve Bell says, “Just because the product is LEDVANCE doesn’t mean it contains OSRAM components. You can get an idea of the connection between LEDVANCE and OSRAM by looking at the LEDVANCE website. Based on your test results, I can say that the LEDs are not OSRAM products.”
In the continuation of the work, there are heavy criticisms in many areas from PCB thickness to the thermal conductive material used.
