Hi,

In a previous job I got very familiar with the EPA rules which lowered my  
already low opinion of the EPA. One problem is that the disposal of the  
CFL bulbs should be at a hazardous waste facility certified to handle  
mercury not at a non-hazardous sanitary landfill. Technically you could be  
charged with a federal felony if you improperly dispose a hazardous waste  
- I am not sure if there are any minimum quantity.

While incandescent bulbs used more energy they were non-hazardous waste  
when they burnt out.

Also, CFL can aggravate certain medical problems which incandescent bulbs  
never did.

Often overlooked is the manufacturing process for CFL and LED bulbs may be  
more damaging to the environment than for incandescent bulbs even with the  
higher energy consumption.
