Impervia LED Column

The Dexeco Impervia LED Column is now available with our latest L3 LED card allowing us to dramatically improve the output, efficiency and control.


The Dexeco Impervia LED Column is now available with our latest L3 LED card allowing us to offer improvements in the output, efficiency and control. The L3 card also allows us to offer up to 13,300 lumens with constant lumen output (CLO) whereby the driver adjusts output over lifetime to maintain the output of the source eliminating lumen depreciation. The L3 LED card is also designed to incorporate a lens over each LED on the card ensuring excellent light control. A range of lens options are available giving asymmetric distribution for roadway applications, as well as wide and narrow distributions.

The L3 LED card has been designed in conjunction with Lumileds and is unique to Dexeco allowing us to offer a high quality European manufactured source and driver with 5 year warranty. This functionality is combined with our unique R11 sensor providing presence detection and ground level remote control. This combination of features allows us to produce one of the most versatile and energy efficient column top luminaires available on the market today.

We also offer the column top in two other sources, Philips LLM module and our bespoke L2 card developed in conjunction with Philips. Both these sources utilise traditional reflector design offering symmetric distribution with the same sensor control and constant lumen output features avaliable with our L3 offering.

LED Benefits

  • Dextra only use Philips, Tridonic and Osram drivers offering thermal and voltage protection with 50,000 hour life time and optimal circuit efficiency.
  • The Lumileds 3535HE chip is used in the majority of our luminaires, this is amongst the most efficient mid power sources available on the market capable of operating up to 190lm/w at a chip level.
  • Three step Macadam’s ellipse of the source which when used with opal diffuser offers a one step ellipse at luminaire level.
  • Colour rendering index of 80. Colour rendering index of 90 available on request.
  • Available in a wide range of colour temperatures from 2200 kelvin to 6500 kelvin.
  • Customised circuit designs unique to Dextra utilising high chip counts ensure that the chip is operated far below maximum operating temperature and current ensuring optimal efficacy, lifetime and lumen maintenance.
  • Lumen Maintenance over life – Our LED designs ensure that the LED chip is effectively thermally managed and operated at low current both for maximum efficiency and to ensure that lumen maintenance over life time is far superior to fluorescent or HID sources.
  • 5 year warranty (see warranty section).
  • Dimming availability – Nearly all LED luminaires in the Dextra range are available with all common dimming options including HFR analogue dimming, Switch Dimming, Digital Addressable Lighting Interface dimming and Tridonic Digital Dimming (DSI).
