•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
