About this item

• ONLY for OttLite 13W Lamps Purchased AFTER 2008: The OttLite 13-Watt Replacement Tube with Electronic Ballast Type E is designed only for OttLite lamps purchased AFTER 2008. If you purchased your lamp before 2008, you need the older tube with a magnetic ballast (Type A). Includes 1 bulb.
• 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 T1333E, Z17113, 7T13CH-CE, B413SP, 7T13CH-SE, T59J33, ZRS113-CA, T13WLE, or PL13-E 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.
• 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 Better Perspective on Health: Established in 1989 by photobiologist and natural light innovator Dr. Ott, OttLite has dedicated itself to creating natural lighting solutions that enhance clarity and visibility. We carry on Dr. Ott's legacy today by leading the way in technology that prioritizes health in lighting.
