Review on 🐠 Large Aquarium Accessory: biOrb 45994.0 MCR Light for Enhanced Performance by Melissa Lopez

I really like this light. I've only had it for about a month, but everything is fine. Most of the controls are self-explanatory, with the exception of using the programming function. To do this, start at the time when you want the daylight to take effect. Turn on the light with the switch. Then click on the time function to indicate how long you want the daylight to work. It took me 14 hours. The light turns blue. WAITING! After about 15 minutes, the light switches back to the daylight white setting. its end. After 14 hours the blue light will turn back on for the night setting and stay on for the remaining 24 hours or 10 more hours. Then the cycle repeats itself. Hope that helps.
