You can make 3 intensity adjustments with the AI SOL. The intensity adjustments correspond to the 3 different color LEDs.
The AI SOL Blue has a round module with 1 super blue LED, 1 blue LED, and 1 white LED.
The AI SOL controller has a round knob that you spin to go through the different menu options. The controller setup is very simple. You turn the knob to the menu to change the date and time. Gently, push the knob down and then set the date and time. Turn the knob again until you get to the setup timers menu. Gently, push the knob down, choose a timer, set the time you want the light to come on, set the ramp time, set the intensity % for each LED color (Super blue, blue, white), set lunar cycle yes/no, and you are done. Go on to the next timer and so on. You can set up to 14 different timers.
For example, I have something like this set:
Timer 1: 12PM, ramp 60 minutes, Super blue 48%, Blue 48%, white 46%
Timer 2: 10PM, ramp 90 minutes, Super blue 2%, blue 2%, white 2%, lunar cycle yes
Timer 3: 4AM, ramp 60 minutes, Super blue 0%, blue 0%, white 0%
Timer 4: 9AM, ramp 60 minutes, Super blue 2%, blue 2%, white 2%, lunar cycle yes
The AI SOL has very direct light. If you have ever used an LED flashlight, you understand. I have 2 AI SOL Blues on a 45 gal. 1 AI SOL wasn't really enough light. I wasn't interested in lighting only the middle 40-50% of my tank. 2 AI SOLs on a 45 gal is just about right. 3 would be even better. If I could have 1 mounted horizontally and the other 2 mounted on either side at an angle, I feel that would be perfect.
