LED lights are generally considered better than halogen lights in the UK (and elsewhere) for several key reasons:

• Energy Efficiency

          LEDs use up to 80-90% less electricity than halogen bulbs.

          In the UK, where energy prices are relatively high, this translates to significant savings on energy bills.

          Example: A 5W LED can provide the same brightness as a 35-50W halogen bulb.

• Longer Lifespan

          LEDs can last 15,000–50,000 hours, compared to around 2,000 hours for halogens.

          This means less frequent replacement, which is more cost-effective and convenient.

• Environmental Benefits

          Using less energy reduces carbon emissions—a priority in the UK’s move toward net zero by 2050.

          LEDs contain no harmful substances like mercury (which is found in some other light types).

          Longer life = less waste in landfills.

• Cost Savings Over Time

          While LEDs cost more upfront, they pay for themselves through lower energy use and fewer replacements.

          The UK government and energy companies have promoted LED adoption through incentives and subsidies in the past.

• Less Heat Output

          LEDs produce very little heat, while halogen bulbs get very hot (can cause burns or even fire risk in enclosed spaces).

          Safer for homes, especially around children or flammable materials.

• Better for Regulations

          The UK and EU have been phasing out halogen bulbs due to their inefficiency.

          The sale of halogen lamps was banned in the UK from September 2021. Following this ban, the European Commission has             introduced regulations under the RoHS Directive effectively banning fluorescent lighting for sale in the EU by 1st Sept 2023.
