This is the second in a series of three video segments on LED tubes. This video covers 4' LED tube retrofits for T12 4' Fluorescent bulbs while the other segments cover 2' LED tubes for 2' T12 Fluorescent and 8' LED tubes for 8' T12 Fluorescent replacements.
The video highlights the performance of the LED Tubes over the T12 Fluorescent bulbs by using an example: For buildings with an Electricity Cost of $.10 per kWh the property areas that would benefit most would be the areas with a weekly illumination run time of 24/7. This would mean that Parking Garage LED tubes, Exit Stair LED tubes, Hallway LED tubes, or Warehouse LED tubes, could each save $26.28 per year over a T12. This savings comes from taking the Annual $39.42 Cost to Operate a Single 4' T12 45 Watt Tube and subtracting the 4' LED 15 Watt tube which only uses $13.41 of electricity per year.
The video uses the same property types and 24/7 run time but changes the Cost per kW to $.20 for comparison. At $.20 / kWh, the annual Cost to Operate a Single 4' T12 45 Watt Tube is $78.84, while the 15 Watts LED Tube only costs $26.28 to operate per year. This yields a savings of Savings of $52.56 per LED Tube retrofit. The video includes data on T12 Fluorescent Tubes that are less than 4ft long. Residential: 331,790,000; Commercial: 410,460,000; Industrial: 24,006,000; All Sectors: 766,256,000 (Source: U.S. Department of Energy)
Sample NYC Rebates: Rebate on Annual kWh Saved: $.13 for 24/7 operations: Rebate Calculation: T12 45 Watts to LED 15 Watts = 30 Watts Saved x 8,760 Annual Hours /1,000 = 262.8 Annual kWh Saved. 262.8 Annual kWh x $.13 = REBATE: $34.16. T12 LED Rebates are an excellent way for New York City Property Owners and Managers to make the retrofit of LED Lighting more affordable.
This video also speaks to LED Tube Thermal Management and invites the Independence LED Authorized Resellers to visit the USA manufacturing plant to review the LED tube technology and the advantages of LEDs that are made in America with domestic and imported components. The Independence LED Tubes meet the Buy America standards and the UL Classification.
