Energy saving tips:

From offices to retail we have saved businesses around the UK thousands! The best saying I have heard in 2017 is ‘a great way of creating green energy is stopping it at the source’, i.e. change your energy eating lighting to LED.

LED Lighting a new technology:

LED lamps and tubes have many clear advantages, here are just 3 that you might like to know about:

  1. LED lighting will reduce your energy bill:
    • In a climate of financial austerity and rising energy costs, reducing your own energy costs by fitting LED lighting will have a significant effect on your overall outgoings.
    • LED lamps will reduce incandescent and halogen lamp energy usage. A 400W hi-bay replaced by a 128w LED hi-bay unit is a 73% reduction.
    • Over the lifetime of an LED hi-bay unit (50,000 hours) it will consume 6,400kWh (at 10 p/kWh) costing £640. Over the same period the halogen equivalent will consume 24,000kWh
    • costing £2400. That’s £1760 saved for each hi-bay replaced by an LED.

  1. LED lighting will reduce your carbon footprint:
  • A 400W metal halide hi-bay lamp replaced by a 128W LED hi-bay unit is a reduction of 73%.
  • Over the lifetime of the LED hi-bay unit (50,000 hours) it will emit 3.49 tonnes of CO2. The metal halide equivalent, over the same period, will emit 13.03 tonnes of CO2.
  • Currently the Government’s CRC scheme will be levying £12 for each tonne of CO2 emitted meaning an extra £156.96 tax saved on each hi-bay replaced by LED.

  1. LED lighting will reduce your maintenance bill:


  • Maintenance is not just the replacement cost of the lamp but also the cost of both personnel and equipment needed to make the replacement.
  • A 400W metal halide hi-bay lamp will cost, typically £16. A metal halide hi-bay lamp will need replacing frequently. In order to do this, it will require the cost of high access equipment hire (£120 / day) plus the cost of at least 2 qualified personnel for a couple of hours (another £40) without even considering any process down time to enable the replacement.
  • With an LED hi-bay unit lasting over 3 times the average rated life the metal halide it is replacing, the provable maintenance cost saving is in the region of £528 per hi-bay replaced by LED.

Those 3 reasons alone add up to a saving of £2445 for every 400W halogen hi-bay lamp replaced by a 120W UK LED hi-bay unit or £1.17 per 24hr operation of each hi-bay unit.

All lamps have an average rated life of 50,000 hours and are fully warranted for 5 years.
