Key Points

  • Available in two types – anodised and stainless steel. Different coloured lighting options are also available including blue LED and normal LED lighting.
  • Each lamp uses just 240W of power but produces the equivalent of a 1Kw conventional metal halide lamp.
  • Great for the environment with savings of up to 72% on either electricity or fuel compared to conventional lamps.
  • 0-100% dimmable and 14 times longer lifespan than conventional lights.
  • Each pen or tank can be independently controlled, allowing dimming and brightening to be set out of normal hours
  • Up to four lights can be controlled and are dimmable from one control box.
  • Incredibly simple installation.
  • Less energy use means it is better for the environment than conventional lighting.
