The Pixel-Free LED™ 360° End Cap is a great way to finish off your Pixel-Free LED™ 360° flexible tube light. The silicone end cap is specifically designed to fit directly with the 25mm DIA version of the tube light. Make sure to glue this product with a silicone glue to adhere properly. Choose the drop down window between the front or rear end cap. The rear end cap is a flat design meant to cap the end of the tube light. The front end cap has a hole for cable egress, so you can connect your power to this side. This is especially handy if you plan to cut the LED tube light to length.
