  1. 1. E8 Group – CPD Low Energy Lighting Friday 6 th March
  2. 2. <ul><li>What is all the fuss around low energy lighting? </li></ul><ul><li>Environmental benefits </li></ul><ul><li>Electricity Bills reduced significantly </li></ul><ul><li>Reduced heat production (95% of an incandescent bulbs energy used as heat) </li></ul><ul><li>Remains one of the easiest and cost effective ways to improve the efficiency of your home or business </li></ul><ul><li>Negativity and scepticism surrounding the technology </li></ul><ul><li>Still only 6 of 23 light bulbs in the average UK home are low energy </li></ul><ul><li>Legislation & Policy </li></ul>Introduction
  3. 3. Myths <ul><li>They contain mercury so are dangerous </li></ul><ul><li>They aren’t dimmable </li></ul><ul><li>They give off a horrible white/blue light </li></ul><ul><li>They warm up too slowly </li></ul><ul><li>They aren’t bright enough </li></ul><ul><li>The government are ‘banning’ incandescents </li></ul>
  4. 4. <ul><li>Compact Fluorescents (CFLs) </li></ul><ul><li>“ A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite mercury vapour in argon or neon gas, resulting in a plasma that produces short-wave ultraviolet light. This light then causes a phosphor to fluoresce , producing visible light” </li></ul><ul><li>- Uses one fifth of the energy of an incandescent bulb </li></ul><ul><li>- They don’t have to look like the bulbs you get free from your energy supplier! </li></ul>÷ 5 =
  5. 5. <ul><li>Light Emitting Diodes (LEDs) </li></ul><ul><li>“ Are they the future of low energy lighting?” </li></ul><ul><li>ADVANTAGES </li></ul><ul><li>90% Energy Savings </li></ul><ul><li>Extremely Long Life </li></ul><ul><li>Reduced Heat </li></ul><ul><li>DISADVANTAGES </li></ul><ul><li>Expensive </li></ul><ul><li>Not yet widely available </li></ul><ul><li>Advancements to come </li></ul>
  6. 6. <ul><li>New phase halogens </li></ul><ul><li>“ The cheats way out?” </li></ul><ul><li>30% energy saving </li></ul><ul><li>Double the lifetime </li></ul><ul><li>Dimmable </li></ul><ul><li>Halogen capsule which keeps heat in the filament </li></ul><ul><li>Cheaper than other energy saving alternatives </li></ul>
  7. 7. Legislation / Policy Low Energy Luminaires <ul><li>Q: What is a low energy luminaire? </li></ul><ul><li>A: A dedicated low energy light fitting with an integrated ballast so that it will only take low energy light bulb </li></ul><ul><li>“ Current UK building regulations state (in part L1 of the regulations) that a certain number of dedicated low energy light fittings must be installed within 'new build' UK homes and extensions. Certain rules also apply for 'new build' offices and commercial properties.” </li></ul><ul><li>Builders currently install a minimum of 30% of low energy luminaires in new build properties to comply with the regulations </li></ul><ul><li>But often pulled out and thrown away by the owners due to a lack of availability of specialist bulbs! </li></ul>
  8. 8. Phasing out of the incandescent light bulb <ul><li>“ A voluntary agreement between the government, manufacturers and retailers to phase out incandescent light bulbs in the UK” </li></ul><ul><li>75-100W A-shaped (Jan 2009) </li></ul><ul><li>60W A-shaped (Jan 2010) </li></ul><ul><li>40W A-shaped (Jan 2011) 60W golfball-shaped and candle-shaped (Jan 2011) </li></ul>
  9. 9. Some figures <ul><li>Changing 8 x 50W halogen spot lights to 11W Megaman CFLs would cost £60 and save…. </li></ul><ul><li>£55 per year </li></ul><ul><li>£825 over the life of the bulb </li></ul>
  10. 10. Low Energy Bulbs <ul><li>Candles </li></ul><ul><li>Golf Balls </li></ul><ul><li>GLS </li></ul><ul><li>Dimmable </li></ul><ul><li>Day Light </li></ul><ul><li>Reflectors </li></ul><ul><li>HALOGEN Spot </li></ul><ul><li>Light replacements </li></ul>
