What are LED Bulbs and Why You Need Them in Your Home

SAP, or Standard Assessment Procedure, is the calculating platform that is used in the UK in order to produce the energy efficiency of homes. There are many factors that a SAP Calculation takes into consideration such as wall, floor and roof construction, as well as glazing, heating, and lighting. Building Regulations in the UK had a major update in June 2022, making it more difficult for SAP Assessors to design a house that meets the latest energy rating requirements. Very often, SAP Assessors find out that they need to combine a complex solution of photovoltaic panels and air source heat pumps in order to get a proposed dwelling to “pass” the dwelling energy rating targets. However, an easy thing to achieve is the lighting, and that is almost always achieved with the use of LED lighting.

Epc4less, a nationwide supplier of SAP Calculations to architects and homeowners says that low-energy lighting plays a key role in reaching better SAP ratings and reducing household energy costs. LED bulbs offer the ultimate in lighting efficiency and longevity to maximize savings. LED bulbs operate differently compared to traditional incandescent lights. Rather than heating a fragile wire filament to produce light, LEDs utilize tiny semiconductor chips to create illumination through electroluminescence.

How LED’s work

When electricity is applied, positive and negative charges flow through specially engineered semiconductor material inside an LED bulb. The movement of charges causes electrons to release photons or particles of visible light. This rapid and efficient energy-to-light conversion makes LED bulbs extremely energy efficient compared to outdated bulbs that waste energy as heat. The process of electrons emitting photons via applied current is known as electroluminescence-the key to LED technology.

Understanding LEDs: Light Through Semiconductors 

Rather than making light through heat, LEDs utilize electroluminescence to emit light. Applying electric current makes electrons move through semiconductor chips. Electron movement generates photons or particles of light. The color of light depends on the semiconductor compounds used.

7 Reasons to Switch to LEDs

LEDs justify slightly higher initial purchase prices over time through electricity savings and practical advantages:

Lifespan: Last 10+ years (at least 5-8 years guaranteed) with average daily use.

Durability: Solid-state design handles vibration. No fragile filaments. 

Versatility: Available in a wide variety of shapes, sizes and colors.

Dimming Capability: Seamless dimming control from full brightness down saves even more.

Environmentally Friendly: Mercury is accessible for home use compared to fluorescents.

Minimal Heat Loss: Minimal heat emission while on or idling.

In new homes, low-energy LED lighting is an easy way to increase SAP rating by 1-3 points. If you are building a new home, Alex Papaconstantinou, founder of epc4less, recommends that you talk to a SAP Assessor on how to best design lighting and interior at an early stage of the design process, instead of leaving lighting to impulse buying long after the property has been completed.

In existing homes, the super energy efficiency, longevity, and eco-friendly design of LED bulbs make switching from traditional lighting a sound decision. Households reap the rewards for months and years through lower utility bills
