Ok folks, just found something really cool that may help you. I am running the AI Prime, and have been using the iPhone app mostly for control. Recently, I began playing with the web interface, and have found some new added functionality, to include color temp settings!
First, a disclaimer. I am not an expert, in fact I'm a newbie. I don't work in the pet/aquarium/light industry. These settings are from the programming for the Prime, which may share some similarities with the Hydra series, or, may not. These settings may nuke your whole house.
When I switch control to manual, there's a little semi bullseye icon next to the sliders. If I click on that, it takes me to a screen where I can select the desired color temp and intensity by using just two sliders (one for temp, one for intensity)! How cool is that?
Now, please pardon the poor quality photos ahead, these are cell phone shots of my laptop screen, so they look funky.
Here is the screen where you can select color temp and intensity:
Now, I'll show you the settings (set by AI) for a range of color temps from 10k to 20k, all were done at 50% intensity. Here you go:
10k
12.5k
15k
17.5k
20k
Good luck!
