Need a little bit answer

[Gordon Lehmann]

My main lamps have this voltage I measuring out of the original
Controller that means I can use resistors to pull down voltage for each lamp
Aqua Medic Aquarius Lights original voltage
0% = 3,26V
25% = 2,43V
50% = 1,62V
75% = 0,82V
100% = 0,00V

Aqua Medic Ocean Twin LED original voltage
0% = 1,80V
25% = 1,36V
50% = 0,90V
75% = 0,46V
100% = 0,00V

Aqua Medic Reef LED measuring voltage coming soon
