Electric Lighting Choices

Lamp technology. For the greatest energy efficiency and best color rendering, school lighting should employ either fluorescent T-8 or T-5 linear lamp technology with electronic ballasts. The latest T-8 lamps, called second generation, produce more than 10 percent more light per watt than the original T-8 lamps and 50 percent more light per watt than the old T-12 lamps (still the most commonly used lamps in older schools). The second-generation T-8 lamps are currently about 30 percent more expensive than ordinary T-8 lamps, but their superior color and light output are worth the cost and they last about 20 percent longer. In a typical classroom, the added cost of purchasing second-generation lamps (as compared to T-8 generic lamps) is about $5 per year. However, if the additional light from the lamps is utilized through good design practice, the classroom will use about 200 fewer watts and will save about $50 per year in energy costs.
