  1. T8 LED Replacements – what's the story? Dave Tilley, Managing Director – Lo2

  2. Messages • Energy is not just an environmental issue it is a business one too. • 19% of the worlds energy is attributable to lighting. • It is predicted that without significant reductions in energy; by 2014/15 demand will be >supply.

  3. Drivers • Energy Prices • Legislation • Technology • Compliance “There is a new body of influence in the business environment”

  4. LED Tube - Principals • Balance between; Power – Lumens – Life • Instant light and dimmable. • Complex Construction; weakest point determines quality. • Standards are not currently available.

  5. Energy Star Scheme • American Scheme. • Voluntary Partnership; DOE, EPA & Manufacturers. • Independent Testing. • Labelling System. • Promotes energy efficient products.

  6. LED Tube Comparison LED – there are no constants

  7. LED Tube Evaluation EXAMPLE – 100 units, 4200 annual operating hours, £0.10 Kw hour

  8. LED Tube Analysis

  9. What About Long Life Fluorescent Fluorescent tubes average rated life is the key factor

  10. The Maths Maintenance regime (reactive, PPM) is the important factor NOT ENERGY

  11. Not Forgetting • Lumen Depreciation • CRi • Service Life • Gear Loss • Switching Cycles

  12. What are the real Issues • How do we know the performance data is credible? • Thermal management is essential. • Independent testing will provide validation. • Understand the source design, manufacturing and testing process.

  13. Enhanced Capital Allowance • Defines performance criteria for ECA. • 6000 hours continuous system testing. • 95% KPi for lumen depreciation. • Applies to LED signage products. • Currently 2 products qualify.

  14. LED Tube Applications • LED is a luminaire with a 120˚ controlled light. • Corridors. • Warehouse isles. • Signage. • Cold environments. • Cover Guard. • Operations where maintenance costs are high. • 24/7 operations. “Where the LED Tube adds true value”

  15. LED Tube Luminaire • Slim Battens. • Modules; recessed and surface. • Wall washers. Maintenance is simplified

  16. Summary • Energy reduction is essential but not at the expense of lighting quality. • Standards are required to protect the client and the technology. • “Always” determine the manufacturing source. • A warranty only has value if the business still exists! • If it sounds to good to be true it probably is!
