dimming facts for led products
... • Some manufacturers do not follow the IES standard. This leads to LED drivers and lamps that claim 0-10V compatibility but drop out or pop on, or dim backwards with the lowest output at the top and the highest output at the bottom. • The control signal is a small analog voltage and long wire runs c ...

EV-12V-2200-33D 12V 26W Dimmable CV DC LED
... All Illuminous dimmable drivers will dim from 100% to 5%. Each LED has a Vf (Forward Voltage), typically is 3V, and when the driver dims below this voltage, it will simply stop working. So dimming performance is a factor of the LED, not the driver. Dimming performance is optimal at greater than 50% ...
