Hi !!

i have 15 lumia 5.1 ( http://www.ledgroupbuy.com/lumia-5-1-100w-full-spectrum-5-channel-led/ )
the seller recommend to power ONE of them
*******************************
Cheapest method is to use:
5x http://www.ledgroupbuy.com/meanwell-ldd-700hw-led-driver/
and to power those LDDs you can use 1x http://www.ledgroupbuy.com/250w-48v-5-2a-dc-power-supply/
**************************
i have to buy " ledcontrol4 passive " to dim them through profilux
however there is no big cost diference between ledcontrol4 passive and ledcontrol 4 active
so if i use ledcontrol4 active i dont need the drivers and power supply right ?
the question is.....
what i need to control 15 lumia 5.1 by ProfiLux 3.1N eX
thank you...........

No in general. Reasons:


LEDcontrol4active isn´t available anymore, you have to use LEDcontrol4 V2 if you want to use a GHL LED control
LEDcontrol4active and also LEDcontrol4 V2 is able to power LEDs with constant Voltage input only. Your LEDs need constant current instead, so a LED driver is mandatory.
LEDcontrol4active and also LEDcontrol4 V2 don´t have an own power supply so power supplies for the LEDs and the PWM signals are needed.



To connect this LEDs to a Profilux, you need all three kind of devices

LEDcontrol4 V2 or LEDcontrol4passive to convert 1-10V signal to PWM (not neccessary in general, but you have to use the 1-10V signal for the drivers otherwise)
LED driver - but not the shown types but dimable ones
two power supplies - one for the LEDs and another one approx. 5V to power the PWM signal from the LEDcontrol4 V2 or LEDcontrol4passive
