Plurio - Thorn Lighting

Sustainability
Plurio in action: fast payback - and better lighting too
Up to 72.5% energy savings!
Sustainability
Electric lighting in urban areas has a major impact on
sustainability. The key to sustainability in lighting is eco-design,
efficient operation and planned recycling at the end of the
product life.

Eco-design
Thorn employs life cycle assessments, as per the Energy-using Products
Directive (EuP), to check the environmental impact of its products
through life. This ensures that care is taken during design to employ,
absolutely, the minimum amount of restricted hazardous substances -
Plurio complies with the RoHS Directive - and that the minimum amount
of virgin materials, water and energy are used during manufacture.
Finally, Plurio’s light distribution is designed to reduce obtrusive light
and sky glow according to I.L.E recommendations.
Efficient operation
The generation of electrical energy required for lighting is a major
contributor to CO 2 emissions. For every kWh of energy 0.42 kg of CO 2
is liberated and added to the 'greenhouse' gases in the atmosphere,
increasing global warming.
The most energy consumption by the product is clearly during
operation, which can be influenced by prudent design and component
selection. For Plurio the key elements are high performance optics
employing modern light sources (no mercury types), electronic gear
and the option of mini photocells.
With efficient products, correct lighting scheme design and the use
of control systems substantial energy saving can be made without
jeopardising the quality of the required lighting condition.

Proposal 1 : Plurio 57W TC-TEL (4300 lm)
Plurio 57W TC-TEL provides 45% more light on average than
Sphere125W HME while consuming 54% less energy.
Proposal 2 : Plurio 70W HSE (5900 lm)
Plurio 70W HSE lights twice as much as the Sphere 125W HME,
while saving 44% energy.
