My local home improvement store (Menard's) was selling the last of their true incandescent bulbs (60 watt, 40 watt, etc.) on clearance. Everything is moving to the CFL's (compact fluorescent) bulbs. Now even the bulbs that look like incandescents are actually CFL's inside. CFL packaging shows actual wattage PLUS the wattage bulb it's replacing (60 watt, etc.) Get the incandescent bulbs while they're available if you use them to heat homemade incubators, brooders, etc. because CFL's generate light but not the heat . The CFL in the lamp beside me has been on for hours and I can reach over and literally hold onto the bulb comfortably. Never fear... white and colored heat bulbs are still sold at pet stores... for 10 bucks a piece as usual.
