AQUACULTURE RANGE: Floating Photoperiod Light for Tanks & Hatche r ies


Developed in response to the requirement for an efficient photoperiod light for tanks, ponds and raceways, Turtle is an entirely self-contained floating unit, housing a highly efficient metal halide discharge lamp together with associated control gear. The starter is safely enclosed within the unit, this avoids the hazard presented by systems that transmit high voltage ignition pulses via inadequate cable and connectors from a cage side mounted control pack to the underwater lamp.

Turtle’s design makes use of the critical angle optical principle to minimise light escape, by using the water surface as a mirror (see illustration below).

The position of the discharge lamp, relative to the water surface, ensures that light cannot pass directly through the surface, providing the added benefit of easy stock observation.
