Uniform light spectrum & output

Goodbye 'disco ball effect.'


The Dimmable SunPower uses T5 high-output fluorescent bulbs that are available in a variety of colors that, when combined, allow you to achieve a unique color to suits your aquatic life and personal preferences. These bulbs produce a blended spectrum directly over your tank. Whereas, many non-diffused LED fixtures* utilize various points of individually colored lights. When these lights radiate over your tank and hit the flowing water below, you may see what is commonly known as a ‘disco ball’ effect of colored lights and shadows moving over the coral and sand below.
* The use of LED light diffusers, like those found on the ATI Straton LED, will help produce a more uniform light spectrum and minimize the disco ball effect.
