The OttLite 13 watt replacement tube delivers the right mix of brightness and contrast to bring true colors and comfortable clarity to your world so you can enjoy your time even more. You’ll see colors accurately and fine print and details with ease under this unique low heat, low glare illumination that helps reduce eyestrain.

There are TWO 13w Replacement Tubes. Here's how to select the right one:

The older 13 Watt Replacement Tube is for lamps with a magnetic ballast. To keep it simple, we'll call this tube Option 1. The newer kind of tube is used with lamps that have an electronic ballast. We'll call them Option 2.
How do you tell the difference? Glad you asked! We've put together this guide to help:

1. When did you buy your lamp?
Before January 2008 - This is the bulb you need

After January 2008 - See Question 2.

2. Is there an “E” on your tube, or bulb box? Note that there are two places the “E” might appear.
Yes - Option 2.

No - This is the bulb you need

Still not sure? Please contact Ottlite customer service at 800-842-8848. They’ll be delighted to help!

    it was not easy to find the part# cross reference but on-line chat from Shawn was quite helpful. I ordered more to qualify for free shipping. My parts all arrived on time, well packaged, via Canada Post. I will use Lines Distributors again.

    How wonderful to find a Canadian distributor of OTTLite bulbs! After consulting about the bulb type needed for my 30 - 40 year old floor lamp, I was able to order the correct bulb and have it delivered in less than a week! That's what I call service!!
