Compact Fluorescent Replacement Bulb for Bedroom & Living Room

If you purchased your lamp after 2008 and there is an E on your tube or box, then you need the electronic ballast (this one). If you purchased your lamp before 2008, you require the older tube with a magnetic ballast (Type A). This replacement tube is only for OttLite 13W Lamps Purchased After 2008.

Examine your current bulb and check if the 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, so measure your shade and/or the bulb you're replacing to ensure the length is suitable. If it's longer than 7in, you will need a different bulb.
