Constant voltage/ constant current drivers offer the following advantages ove high voltage cosntant currenat “-C” drivers:

  • lower maximum voltage for safer operation
  • maximum flexibility for expansion – any number of COBs can be added later on. Every COB added increase efficiency of entire array


Please note all COBS must be same series of similar voltage profile, you cant mix 1212 and 1818 as the lower voltage cob will not light. it is also not recommended to mix gen 5 and gen6 chips or Citis with luminus, etc. Despite the fact that they are all “50V chips”, slight voltage differences may cause unpredictable results
