I built two separate led fixtures a few months apart; both with constant current drivers dimmable via built in potentiometers between 350mA and 700mA. I also purchased a plug in energy consumption moniter to set the lights to certain power outputs. To get to the point; after a few months I noticed that the energy consumption moniter had gone from 100W to 30W on one of he fixtures without me touching the driver so I turned the potentiometer up to maximum and it only went to 170W when it had previously been 250W and on the lowest setting it is now reading 7.5W which is crazy as the minimum forward voltage of the diodes is 280 odd volts and the minimum operating current is 200ma on some of the diodes and they are lit. I plugged the power meter into my other fixture and it also said the power consumption had gone down drastically; MUST be the energy meter right? Well I'm not sure as when I plug it into any other device it still gives what seems to be accurate and close to specification power readings. Is there anyway the circuitry of these drivers could be interfering with the power meter?
Thank you in advance for any help!
