This is an excellent, inexpensive, reliable way to run LEDs. There are no control or dimming functions, just on/off. This driver outputs a max of 35W (to determine total wattage of each LED, just multiple the LED voltage by the LED current, and that sum is your answer). Ensure total LED wattage is less than 35W.
500ma version outputs 25-70V (Perfect for running up to 18 of the 365nm UV or 420nm Hyper Violet LEDs)
700ma version outputs 15V-50V
1050ma version outputs 11V-33V
