18w Replacement Tube

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 our Customer Service team 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.
