About this item

• Energy Efficient: The output of a 13-watt OttLite bulb is roughly equivalent to that of a 60-watt incandescent bulb. This light bulb is rated to last up to 10,000 hours.
• A Healthier Way to See: Since its founding in 1989 by photobiologist and natural light research pioneer Dr. Ott, OttLite has focused on developing healthy, natural lighting that helps people see everything more clearly. Today, we continue to bring Dr. Ott’s work to life by pioneering advancements in health-focused lighting technology.
• Confirm This is the Bulb You Need: Look at your current bulb and see if model number T13330, T1360A, T38J36-CA, Z23112, OLPL13TC, OTL13TCB, T139EZ, T34J3R, OTL13NATB, OTL13P, T137D0, TRS113-CA, TRSJ36, or T17113 is marked at the base. This replacement tube is approximately 7in long. Measure your shade and/or the bulb you’re replacing to check the length. If it’s longer than 7in, you will need a different bulb.
• Only for OttLite 13W Lamps Purchased Before 2008: The OttLite PL-13-A-FFP 13-Watt Replacement Tube with Magnetic Ballast Type A is designed only for OttLite lamps purchased BEFORE 2008. If you purchased your lamp after 2008 and there is an E on your tube or box, you need the electronic ballast (Type E). Includes 1 bulb.
• Crafted for Optimal Indoor Daylight: Experience clarity while reading instructions, books, and intricate craft details with this gentle, low-glare illumination that accurately displays colors. OttLite bulbs are uniquely engineered to emulate natural daylight inside, minimizing eye strain, allowing you to engage in your favorite activities for extended periods.
