Most lamp specs only spec lumen. Lux and beam angle will be important to achieve a certain Lux at task level. There are many LED tube design from 180 deg to 330 deg. However, a typical LED component has only 120 deg beam. GEMWEL tube uses special reflective material to perform light mixing and project the light forward. When implemented, the tubes perform better than the 360 deg traditional fluorescent tubes at 50%. The payback is less than 1 year for 24×7 operation.
