LED Bulbs

Bulb shape is not just a question of liking the look of a bulb: its about how it throws light. The design of the bulb determines what direction the light goes, so you need to consider what you want the bulb to do.

It is no longer enough to think of about bulb brightness in terms of watts. That was fine when we only had incandescent bulbs, but now we all need to start thinking in Lumens. Which is particularly the case when buying LED bulbs, because the use of the term ‘replacement’ can be abused by bulb re-sellers, and occasionally by lesser manufacturers too. If you wish to replace an old 60W bulb and get a similar amount of light you will need to get at least 700 lumens to get a similar brightness to the old bulb. Knowing your lumens means you will get the brightness you want, and avoid being mis-sold ‘replacement bulbs’

When buying LED lights one need to decide what shade of light you wish to have. The most common shade replicates the warm white shade given off by an old halogen or incandescent bulbs. But as commonly known LED’s can come in any colour you desire.

LED lights can reduce your lighting bill by up to 90%, and lighting usually accounts for up to 40% of your electric bill. LED lights drastically reduce the carbon footprint of your home or business, and emits up to 70% less UV light than halogen bulbs. Compared with a regular halogen bulb, LEDs can last up to 25 times as long- which is a lifespan of up to 50,000 hours.

Below is a very simple calculation based on 100 x 50W bulbs in your house:

  • Current installation: 100 x 50W Mr16 Bulbs
  • Annual operating cost: £1,248 at 12 pence per 1kWh
  • New installation: 100 x 5.5W LED bulbs
  • Annual operating cost: £137.28
  • Saving in electricity cost: £1,110.72 
  • CO² – old installation = 5,670kg
  • CO² – new installation = 624kg
  • Saving in CO² emission = 5,046kgiStock_000045580518_Large
