Halogen Light Unit for REEF ONE Aquariums The low voltage light unit illuminates the biOrb and it’s inhabitants, making the aquarium into even more of a feature. Designed as an easy-to-fit accessory, the light unit doesn’t impose on the biOrb’s attractive shape and incorporates a hole for easy fish feeding.
Replacement Light Bulb for REEF ONE Aquariums The 10 watt halogen bulb in the biOrb light unit should last for around 1200 hours. We recommend leaving the light on for 6-7 hours a day.
