Here is a brief run down on them.
come in lengths 40cm - 160cm
colours Daylight, ocean blue actinic and deep actinic
Mix and match different bar colours to your tank eg 1 x daylight 1 x deep actinic
Control - simple on off via timer or must run through Profilux for dimming and other capabilities, (no built in controller with the light bar)
To buy - work out what light bars you want for your tank and how many, and then match power supply output to light bar output (different power bars sold at different wattages), then work out how many spiltters you require.
Price - No price yet provided for USA but for reference and more info see link below
