LED lighting solutions to save energy and cost

Save energy and cost

  • Save at least 64% energy when switching from 400W lamp to 155W LED.
  • Lower maintenance costs. Lamps are warranted from 3-5 years.
  • Longer rated life of LED (50 000 hours vs 8000 – 20 000 hours).
  • LEDs last even longer in cold conditions (Longer than 50 000 hours).
  • LEDs are more flexible at dimming, switching on and off.
  • LEDs maintain brightness (lumens output) for longer than normal lamps.

How our process works

one-smallA high level assessment of the lighting in your facility is conducted.

An analysis and proposal is put together for your specific needs.

Installation and implementation of the lighting is completed.

The problem with current warehouse lighting

Most warehouses currently use Metal Halides, High Pressure Sodium (orange light) or fluorescent T-Bay lighting technologies.

There are three main problems with these lighting systems:

  1. Light levels are low
  2. Energy consumption is high
  3. Maintenance cost to replace failed lamps is high

Comparison of energy consumption

LEDs can save at least 64% energy consumption and cost, last longer and give off a brighter light than other lighting options.

These figures are based on changing from a 400W lamp to a 155W LED.

The energy impact and cost of upgrading to LEDs

  • Green Power’s projects over the last two years have resulted in approximate savings of 36million kWh.
  • Green Power is focused on providing energy efficient lighting solutions to corporate, commercial and industrial clients.
