The OttLite 18 watt replacement bulb 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.
The output of a 18 watt OttLite bulb is roughly equivalent to that of a 75 watt incandescent bulb. Compact fluorescent bulbs (CFLs), like the ones here at OttLite, require 75% less energy, generate 75% less heat, and last 10x longer than standard incandescent bulbs. However, it's not just about energy-savings, it's also about the quality of the light.
If the base of your existing 18w Type B bulb differs slightly in appearance than the bulb pictured on this page, please contact Ottlite's Customer Service team @ 1-800-842-8848 for instructions on how to safely and easily modify your fixture to accommodate the newer style bulb.
Please check your lamp’s packaging to determine the correct replacement bulb, or contact our Customer Service team for help.

Ott lite replacement bulb
Ordered a replacement bulb for a floor lamp. Had tried unsuccessfully with several other companies to find a replacement bulb. This company provided amazing customer service and follow up emails so I could track my shipment. Well done!!!
Replacement bulb comment
Excellent light bulb. Give bright light. The first bulb lasted a long time
Thank you for prompt service
I have had an Ott light for almost 20 yrs with the same bulb. I was told that the replacement balls were no longer available by someone so I was thrilled to find them on your site
Well I haven’t used it I’m sure it will work fine. Found the tracking section was not up to par. I wasn’t notified until a day later when things moved I E was notified the day after it was delivered that it was delivered
