18 w changed other power drive not bright LED lamp, what reason be?
42 v only do as much as 14 w, this is the most basic request, if I see this kind of drive is absolutely can't use, because the basic common sense all wrong, quality), the voltage is not enough, so is certainly not the light, do you want to buy a maximum output voltage at least 54 v drive
VF values of each lamp bead is about 3-3.4 V, so a series of at least 18 to 54 V, general situation, the output voltage won't do more than 50 V, because it is not safe (of course, the use of isolation was not drive), so will make it 2 and 9 series way for more than 27 V (voltage), but not see your driver clear this After a few short also cannot do 3 * 18 w, because your lights must be 1 w (300 ma), rather than a 3 w (600 ma), current headlight bead hold, within a few hours it broke
Light is normal, do not see your original drive, is 18 series, namely voltage must achieve 3 * 18 = 54 v, 1 to 2 and 10 series of drive, the highest nominal output voltage only 36 v, paragraph 2 of nominal only 42 v (actually this drive is problematic, 16 * 1 w drive maximum voltage should be more than 48 v, actually should be 50 v
