The OttLite T-4 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.

The output of a 13 watt OttLite tube is roughly equivalent to that of a 60 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 our Customer Service team for help.

    Met my needs

    Posted by Susan Wall on 2021 Mar 5th

    The product was exactly I needed. The service provided by Shawn was excellent. Delivery was timely. The packaging? Well i wouldn't pop glass tubes in a bubble wrap envelope to go through the mail. They made it but the individual boxes were all out of square and I was amazed that mone were broken. Regardless, I am a happy and satisfied customer.

    Great find

    These Ottlite replacement tubes are becoming increasingly hard to find as the world, including Ottlite has shifted production to LED. I love my Ottlite desk and floor lamps that use this bulb and am surprised that Ottlite hasn’t designed an LED replacement bulb. But to keep my lamps working, the right bulb is essential. Lines Distributors has the product at a good price. Their online ordering process and follow through is top notch and the bulbs were well packed and shipped quickly. A pleasure to do business.
