LED v Fluorescent - all you need to know

  1. 1. Dialight LED Lighting Technology Comparison: Fluorescent
  2. 2. Technology Comparison Dialight Typical makeup of light source material LED 2 Fluorescent
  3. 3. Power Consumption / Dimmability Dialight Energy savings Replace 400W conventional light source with 150W LED High Bay for immediate energy savings of 60%, even more when you use dimming and proximity sensors. Dimming Dimming options for LEDs include STEP dimming for specified light level percentages or variable dimming for custom light output levels determined by the installer/customer. A special ballast is required to dim fluorescent lamps. Bans “Under the terms of the National Energy Policy Act of 1992 (EPACT) and similar legislation in Canada many of the full wattage T12 lamps can no longer be manufactured due to their relative low efficacy and/or poor color characteristics” (The Lighting Handbook, IES, 10th ed., 7.32). Light Source Dimmability Fluorescent 40 – 264 Requires Special Ballast LED 3 Fixture Watts 8 – 170 Yes
  4. 4. Lumen Per Watt Efficiency Dialight Light Source Fluorescent 40 – 100 LED 4 Lumens/watt Up to 150
  5. 5. Lifetime / Lumen Maintenance Dialight Light Source Fluorescent 6 – 45 LED 5 Lifetime in Hours (x1000) 100+
  6. 6. Colour Quality Dialight Colour Rendering Index: “A measure of the degree of colour shift that a set of test-colour samples undergoes when illuminated by the light source in question, as compared with those same testcolour samples when illuminated by a reference illuminate of comparable colour temperature” (The Lighting Handbook, IES, 10th ed., 6.13). Light Source Fluorescent 60 – 90 LED 6 CRI 70 – 90
  7. 7. Temperature Ratings Dialight Temperature Ratings Heat producing equipment is marked with a Temperature Code to indicate the maximum surface temperature Fluorescent LED Ratings given at 40° C ambient temperature Light Source Fluorescent T4 LED 7 T Rating T5
  8. 8. Mercury Content MASTER TL-D Super 80 14W/865 1SL Mercury Content: 5 mg Dialight LED Mercury Content: 0 mg Disposal The Resource Conservation and Recovery Act (RCRA) and the Universal Waste Rule (UWR) regulate the disposal of lamps containing mercury. LEDs themselves contain no mercury or harmful materials, which require special handling or unique recycling. Light Source Fluorescent Avg. = 1.7mg – 15mg Older lamps may contain 50mg+ LED 8 Mercury Content 0mg
  9. 9. Instant On/Off Dialight Fluorescent Ballast Options: Preheat, Rapid Start, Programmed Start and Instant Start GE T8 Watt Miser: “Lamp warm-up time (i.e. when the lumen output reaches 90% of its maximum) is on average 2 minutes.” Light Source Fluorescent Instant – Couple of minutes LED 9 Warm Up Time Instant
  10. 10. Operating Temperatures Dialight Light Source Fluorescent -29°C to 60°C LED 10 Operating Temperature (°C) -55°C to 65°C
  11. 11. Operating Temperatures Relative luminous flux for fluorescent in extreme temperatures Dialight Relative luminous flux for LEDs in extreme temperatures Light Source Fluorescent -29°C to 60°C LED 11 Operating Temperature (°C) -55°C to 65°C
