Dimmed high current driver vs lower current one
Posted: Sat Apr 14, 2018 2:16 am
Hi everyone! I'm new here and about to start my first COB build. There is a lot of info to assimilate for a newbie, but I'm doing my best
I can't seem to find straight answers to a few questions regarding dimming the COB drivers (lets consider Mean Well hlg-c ones). I will present them in a form of a list.
1) Is running a 2800 mA driver dimmed to 1400 mA the same as running a 1400 mA not dimmed (at max current)? If not, what are the differences?
2) Is the built in dimming feature of the A series driver in any way better than having a separate potentiometer connected to a B series driver? (except for the difference in the dimming range 10-100% vs 50-100%) Say, a 2800 mA driver with a potentiometer set to 50% vs the equivalente driver with its dimmer setall the way down to 1400mA?
I want to put together a simple build:
5 cxb3950 with HLG-240H-C1400A. I would like to be able to adjust the ligth output depending on grow area or palnts needs, without losing much quality.
I hope I have managed to state the issue clearly, please pardon any errors! Lookig forward to reading your answers!
