I'm using a Meanwell LDH-45B-350 Dali driver for currently 4 Bridgelux BXRE-30G0800-D-73 LEDs with forward voltage of 18v at 350mA. The problem is when I switch off the driver, the LEDs still glow a little bit.
I saw in the datasheet today this paragraph in really bad English:
- At dim off,LDH output voltage will drop to the same level as input voltage.To get luminaires complete dark, A please make luminaires are light off when they are driving by the input voltage.
The driver is fed by 24V, does this mean that with these LEDs there is no solution for this problem?
I got the B version and 24v supply because it can drive my 7 LEDs together. The A version can only drive 4.
