    Cost Calculator The pressures on reducing energy, maintenance costs and operating costs will continue to increase so that climate change objectives can be met. Understanding the total cost of an installation over its whole life is becoming increasingly important as budgets become tighter and long term planning is required. The Total Cost of Ownership Tool from WRTL allows you to compare the complete cost of alternate lighting solutions alongside Stela so that you are able to make informed decisions on long term sustainability.

"Introducing this new lighting system across Suffolk has not only helped us to save money and reduce our carbon emissions but has also given us the flexibility to control our own lights, and respond to the local community needs.” Councillor Guy McGregor

Parvis

Parvis is a Classical Heritage lantern with an ornate style that is at home with the grandest of architectural structures and spaces. It is part of a system designed to emulate traditional style Candelabras where multiple luminaires are installed at a single point location using associated ornate brackets and embellished columns. Parvis is typically employed outside stately homes, museums and government buildings as well as in the surrounding areas of parkland, drives and pedestrian squares. Styling however does not compromise performance as a selection of high performance reflectors systems, including the Vectra 1, Vectra 2 and IVA series, combine with up to the minute light sources from high pressure sodium to Cosmopolis to provide the functionality required.



Applications in the range of mounting heights 3.5 to 6 metres with typical installations including :- Palaces, Country Estates, Prestigious Government Buildings. Centres of Tourism in Cities and Towns with strong Cultural and Historical Heritage. Formal Parks and Gardens, Cathedrals, Churches and Religious Centres. Roads, Pedestrian Areas, Precincts and Retail Centres in the vicinity of historical buildings with period architecture.

  • Lamp options range from 50W to 150W SON (Vectra 1), 250W SON (Vectra 2), 70W to 150W Metal Halide (Vectra 1), 250W Metal Halide (Vectra 2) and 45W to 140W Cosmopolis (Vectra1) for maximum coverage of application needs.
  • Materials are Aluminium, Brass and Bronze or Copper and Bronze for corrosion free life and maximum recyclability.
  • Computer designed anodised aluminium one piece reflector systems for precise optical control.
  • IP66 sealed optic system for maintenance free performance.
  • Clear Polycarbonate Bowl to IK 10 Impact Resistance .
  • Range of paint colours from the RAL system or Akzo Nobel Futura selection to complement architectural design.
  • For Brass and Bronze or Copper and Bronze selections, a range of antique lacquers and varnish finishes are available.
