Solidly built, the trans white blade provides even diffusion for NeoPixel LED blades. I used an additional gift wrap tissue and lined the inner wall to provide additional diffusion for my LED strip blade. Simply wrap the tissue around a wooden dowel with slight overlap, about 1/8" and insert slowly in the tube. Keep the tissue together on the dowel as you insert it into the blade until fully installed. As mentioned you should have a 1/8" overlap. Use your fingers to carefully align the tissue and leave another 1/8" space at the top to allow blade tip to be installed.
