About this item

• Designed to Deliver Natural Daylight Indoors: See the fine print of instructions and books and details of your crafts clearly and comfortably under this low-heat, low-glare light that shows colors with incredible accuracy. OttLite bulbs are specially designed to bring natural daylight indoors, helping reduce eyestrain so you can do what you love, longer.
• 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.
• 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.
• Energy Saving: A 13-watt OttLite bulb produces light comparable to that of a traditional 60-watt incandescent bulb. Its lifespan is estimated to reach as much as 10,000 hours.
• 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.
