Hi riu I am building a led grow light and I need to no a few things I got 100 3 watt bridgelux full spectrum 700ma I bought some drivers that are for 18-30 3 watt 650 ma 0.5 amp output voltage dc 33v-68v and 12-18 3watt 650 ma 36-60 volts LEDs I wanna know how I'm supposed to wire all them do I wire like 25 to the 30 3 watt drivers 2 of those i have and i got 6 of the other and like 10 or 12 to the 12-18 3 watt drivers in series or parallel I'm confused about that I hope someone can help a fellow grower out.
wow..thats a lot of stars. Did about 80 once, takes some time but not too bad.
Little confusing how you wrote that up but I'll give it a try.
So the driver 36-60v...You need at least 36v and no more than 60v basically. Assuming the drivers specs are accurate. You need to look at the place you purchased your leds and see what the typical current is for that led at 650 or 700ma. Say its 2.5v....60/2.5 = 24. You can put at the most 24 leds. If the string is dim or doesn't light you may need to remove a few or check with a multimeter what the voltage actually is.
Same process for the 33-68v...
Wire them in series. Positive from driver to positive on star. negative on that star to the positive on the next until you end up with a negative out on the last star to the driver negative. Thats it...
When you use a better brand of driver like meanwell you can count on the driver specs to be accurate and they will normally light up every time if you calculated the leds total voltage right
