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.
• Energy Efficient: The 13-watt OttLite bulb has similar output to a 60-watt incandescent bulb and can last for over 10,000 hours.
• 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.
• 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.
