Pendant Lighting

OVERTANK LUMINAIRE OT2 LED

A new concept in marine aquarium lighting from Arcadia, the OT2 LED combines the high light output and uniformity of T5 lighting with high performance LED panels which create light and shadow in the aquarium and produce a naturalistic ripple effect, normally associated with HQI lighting.

  • Adjust overall colour temperature through seperate dimming of deep blue LEDs with a spectral peak of 450nm, and cool white LEDs selected for a colour temperature in excess of 8000K
  • Multiple high output LED panels which should last in excess of 5 years
  • Independently dimmable high output White and Blue LED’s
  • Independently dimmable Marine White and Marine Blue T5’s*
  • Separate dimming control of T5 and LED sources
  • Radiates very little heat into the aquarium
  • Optional automated dimming controller**

 


LED Information

The LED panels feature two separate groups of LEDs, deep blue LEDs with a spectral peak of 450nm, and cool white LEDs selected for a colour temperature in excess of 8000K. Each group can be separately controlled allowing the overall combined colour temperature of the LED panels to be controlled. The LED panels also have a very long service life and should last in excess of five years in normal use.

Lighting effect using white LED panels only.

This level of control is carried over to the T5 lamps, with six lamps controlled in two groups, one group of four lamps, one group of two, allowing the mix of white and blue fluorescent lighting to be adjusted.

The OT2 LED also radiates very little heat into the aquarium – although the LEDs and T5 lamps do generate heat this is directed into the heatsink and luminaire body which heats the air above the luminaire, not the aquarium. Compared to aquariums lit with HQI lamps, there is a marked reduction in the heating of the aquarium, which will have a corresponding effect on the energy consumption of any connected chiller unit.


Dimming Controller

When combined with Arcadia’s new dimming control unit, the OT2 LED allows unprecedented control of the light levels and colour temperature within the aquarium. The Controller also allows the unit to perform automatic dawn and dusk simulation, moon cycles, random cloud cover etc.

Another advantage of the dimming control available is in energy efficiency, both T5 fluorescent lamps and LEDs use an amount of energy proportional to the dimming level selected, so reducing the output of the T5 lamps by 20% will reduce their power consumption by approximately 20%. Obviously the amount of light your aquarium requires depends on the size and depth of the tank and the coral species that you are trying to keep – for more detailed advice on lighting for marine aquariums, visit the Arcadia website.

Suspension

When it is not convenient to mount the over tank luminaire on to the tank, the suspension kit allows it to be suspended from the ceiling, or from wall brackets.
