  • Troika

An asymmetric 'flat glass' floodlight for 250-600W discharge lamps with adjustable lampholder

  • Ideal for sports, functional and architectural applications
  • Light output is finely controlled to minimise light pollution
  • Four different light distributions for each lamp option. Troika Variable (60°-70°) uses a reflector in conjunction with a variable position lampholder, providing three distributions varying in intensity, beam width and peak angle intensity (I peak).
  • Broad selection of attachments, including a Lux Guillotine. This adjustable vertical light shield enables the light beam to be cut-off exactly where required and is therefore suitable for areas of extreme sensitivity to light spill
