New toy! A generic ebay Lux meter from China for testing light levels. I decided to test the two 20W LED floodlights above my bench by seeking their peak output point on the bench. While both have 20W drivers, one has a normal 20W LED and the other has a 50W LED. My theory in using the 50W LED is that the same power would be spread over more LEDs and because they were being run at lower current their efficiency would be higher, resulting in more light.
