In many cases, this has proven unsatisfactory. After a century, we are becoming more discerning in our lighting choices. In the 1940s, the height of utility was two 60-watt light bulbs in a big fixture in the middle of the kitchen ceiling, cunningly placed so that the cook prepares food in his own shadow. In the wake of the oil embargo and the onset of energy consciousness, lighting designers noticed this problem, and invented task lighting. Consider updating light delivery systems.
Modern tubes are smaller but actually generate more light due to improvements in phosphor chemistry.
Suitable Lighting Compact fluorescent bulbs are great for some locations, and have problems in other places. The lives of all bulbs, including CFs, are shortened by lots of switching on and off. CFs are likely to fail prematurely in places where the electricity is junky, for instance on unconditioned generator-powered systems. CFs sometimes have trouble starting when it's cold or the electricity is weak. Be sure the larger compact fluorescent fixtures fit inside the cover.
