These LED lighting products deliver a very cost effective lighting solution despite the fact that the best HBLED efficiencies are still lower than those of fluorescent tubes. This is because all of our lighting products use a clever prismatic light guide that couples the entire output of its edge-mounted white LEDs to a front-end diffuser system. Together, they spread the light evenly across the panel's surface and make sure that almost every lumen (around 89%) they produce actually gets to where they're needed. This stands in sharp contrast to traditional fluorescent fixtures which can lose up to 45% of the bulb's output to internal reflection and absorption. Click here for Tilux LED Lighting sale.
