As Kien stated above Moon Lights are generaly not used as supplement lighting . They are used to add a moonlight effect. If you are looking to supplement your day lights T5's and LED strips are what you want to use for pop or to enhance colours. I use to Ecoxotic Panarama 10"-12" strips or modules. Two covers my whole 5 foot tank.
