Key Features

With its exceptional 'finned' thermal management system, D-Series is capable of delivering over 100,000 hours LED module life. Offering a wide range of lumen packages and optical distributions, D-Series delivers optimised lighting application designs.

  • The D-Series's diecast aluminium housing acts as its primary heat sink. Its longitudinal fins employ conductive cooling techniques to dissipate heat away from the key LED components and driver that extends the life of the luminaire.
  • Light engine(s) consist of either 20, 30, 60, 80 or 100 high efficacy LEDs (subject to chosen configuration) mounted to a metal-core circuit board to maximize heat dissipation and promote long life.
  • Offering lumen packages ranging from 2,000lm to 36,000lm with efficiencies of up to 142 lpw (Lumens Per Watts) in colour temperatures of either 3000K or 4000K.
  • Three optimised distributions (asymmetric, symmetric and forward throw) delivered by quality LEDs and bespoke UV stabilised optics.
  • LED light engines with 0% ULOR ensuring night time friendly.
  • Available with DALI compatible driver and photocell options enabling dimming facility.
  • Fully integrated into Holophane standard column range.



Forward Throw


Single-piece die-cast aluminium housing, that conforms to EN1706 AC-46500, with integral heat sink fins to optimise thermal management through conductive cooling. LED modules are IP65 with individual lenses, and high grade aluminium housing to transfer heat away from the LEDs and dissipate through the finned housing for cooling. The LED driver is mounted in direct contact with the finned housing for cooling to promote low operating temperature and long system life. Housing is completely sealed against moisture and environmental contaminants (IP65). Installation is via the integrated mounting block and integral arm that facilitate a quick and easy installation.

3000K or warmer must be selected for IDA dark sky certification.

Lighting Design

Holophane offer a comprehensive and professional lighting design service. Our experienced and qualified lighting designers are on hand to provide full project support ranging from simple calculation plots to full complex lighting designs.


Product Matching

Holophane’s history lies in it being the first company to give practical application to the principles of the prism as the ultimate means of light control, harnessing and redirecting the output of light source by prismatic means to provide the best in cost effective, efficient lighting.


More light, less Investment

We believe that our products are better, more cost-effective and longer-lasting. And we'd like you to put that to the test.
