Replace your fluorescent bulbs or upgrade to LED. These light bulbs are the most common tubular bulbs for fixtures inside plants, warehouses, and offices. Select a light appearance to match your existing lighting. If you’re not sure what temperature you need, choose a bulb with more than one light appearance. You can adjust the temperature with a switch.

Fluorescent bulbs contain small amounts of mercury. For disposal information, visit www.epa.gov/cfl. Bulbs that cannot be sold to the listed areas do not meet local regulations for mercury content or energy efficiency.
