Compact florescent bulbs (the smaller coiled version) can be dropped off at local retailers like Home Depot. Long Tube Bulbs similar to commercial fixture types, must be recycled through a hazardous recycling center.
Putnam County has two recycling events each year, one in the spring and one in the fall. You can contact them directly at 845-808-1390, ext. 43150 to inquire of specific dates.
