The information contained here, including test results, should be regarded as amateur information for entertainment purposes only.

The tests that were conducted may or may not be indicative of the performance of any dimmer as; (1) the sample rate was with a QTY of 1, (2) the tests were conducted in an amateur manner, and may or may not be able to be replicated with any degree of certainty, (3) there may be variables that could not be controlled, and which cannot be replicated, and (4) each test was conducted once, without averaging.

For example, the ammeter and voltmeters I used in these tests were simply common devices, and are not sophisiticated enough to accurately measure current and voltage under the pulse width conditions. Their indication is sure to vary depending on the PWM frequency, and the mis-shaping of the dimmer PWM output by a paricular LED fixture (driver).

As well, when testing dimmers on LED Switch-Mode driver fixtures, there were no consistant results, and they changed from test to test. For example, one time I was successful in dimming a Switch-Mode LED, but later, using the same setup, I could not dim that same fixture using that same dimmer.

Do not consider the test results to be a representative of any product... they are simply my ovservations in a point-of-time. I did these tests to urge you to conduct your own test to determine the suitablity of any dimmer in your application rather than relying on my test results.
