The OttLite 20 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 20 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.

Please check your lamp’s packaging to determine the correct replacement bulb, or contact Ottlite's Customer Service team for help.


This bulb is compatible with the following other bulb models:
B34J32, B34J35-CA, B84J35, B84J33, SB20-M, SB20-M-FFP

  • For use only as a replacement bulb with specific OttLite lamps
  • True colors, clear details and reduced eyestrain

    This particular light bulb is getting hard to locate. I was very pleased to find it at Lines Distributors. It was exactly as represented in the photo and description. I ordered it one day and received it the next, and I chose just regular service. It was very well packaged to prevent the bulb being damaged in transit. It was an enjoyable shopping experience. If I require something in the future I will be sure to check if Lines Distributors carries the item.

    None of the bug box stores in our area had this bulb. On line I found Ottlite located in Tampa & they provided information of a Canadian Distributor. The bulbs were available, packed safely for shipment & delivered in just one day! Great service!
