Hi. Im looking to build a DIY COB grow light and Im a little confused. The cob im looking at states that the voltage and current requirements are 30 - 34V and 1500 mA for a 50w cob. Does that mean that 1500 mA is the max current or the operating current of the COB. Could I run a COB like that with a led driver that provides 1400mA constant current? Thanks
