LED Lighting

LED lighting has seen amazing advances over the last few years and you can now get LED bulbs that are direct swaps for conventional household bayonet bulbs, halogen spotlights and even outdoor flood lights.

  • They use 80-90% less energy than the old fashioned incandescent bulbs
  • half the energy of a CFL bulb
  • instantly reach full brightness- unlike the notoriously slow CFLs

The horrendously inefficient incandescent bulbs that wasted a staggering 97% of their energy as heat are now thankfully mainly banned- it’s illegal to produce or import 100W and 60W bulbs into the EU.
