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.

The problem with current warehouse lighting

[gdlr_row]
[gdlr_column size=”1/2″]

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.

LED Metal Halide T-Bay (HO T5)
System Wattage 155 444 356
Load Factor (hrs p.a.) 8,760 8,760 8,760
kWh per annum 1,358 3,893 3,115
Total energy cost p.a (R1.15/kWh) R1,561 R4,477 R3,582
Additional energy cost p.a. R2,916 R2,020
Rated life to L70 50,000 50,000 50,000
Replacement lamps required 5 10

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.
