Technology
All linear fluorescent lamps generate their maximum light output, or lumens, at a very specific temperature. Whenever a lamp operates in an environment that is colder or warmer than the “peak” temperature, light output drops. For T8 lamps, peak lumens occur at 25oC (77oF). For T5/HO lamps, peak lumens occur at 35oC (95oF). Amalgam is a property found in certain linear fluorescent lamps that will maximize the lumen output over an extended temperature range. In extremely cold or hot environments (think walk-in freezers or unconditioned warehouses), designers will use an “amalgam” lamp to maximize light using the least wattage.
Financial
Most turn-key lighting retrofit projects will generate annual savings that typically recover the net investment in 2 to 3 years. Wattage reduction, annual hours of operation, utility rate, rebate incentives, and desired light levels are just some of the parameters that will affect the simple payback.
The Energy Policy Act of 2005 is a Federal Tax Deduction available to Building owners who invest in energy efficient conservation measures for their facilities. Qualified projects will earn up to $1.80 per square foot based on lighting, HVAC, and building envelope upgrades. All projects must meet all EPACT compliance requirements and be certified by a qualified professional.
Unlike other energy conservation measures, lighting energy savings is fairly easy to calculate, measure, and verify. Annual energy savings ($) is calculated by multiplying: total watts saved x annual hours of operation x utility rate.
