What is the light output of T8 fluorescent lamps?
The amount of light generated by 32-watt T8 fluorescent lamps varies considerably from one lamp model to the next. Figure 1 shows the range of values for rated initial light output that are presently published for 121 lamp models by nine manufacturers for different correlated color temperatures (CCT). The number of available models for each rated initial light output is represented by the size of the bubble. For example, at a CCT of 4100 K, there are nine models rated at 2950 initial lumens.
