This line of safety-coated, 49-Watt T5HO fluorescent lamps offers a reduced wattage, longer-life model for enhanced ecological and energy efficiency. The estimated energy savings over the longer rated-life (up to 35,000 hrs.) is $17.50 per lamp, when comparing these models with standard 54W T5HO lamps. By extending the relamping cycle, additional savings will also result from reducing maintenance and recycling costs. The lamps also feature the lowest mercury content in the industry: 1.4 mg. Benefits of enhanced lighting performance include high color rendering, exceptional lumen ratings, and a range of color temperatures.
