@famulare_mike @Don_Milton Does the math work out to such a small device having any meaningful efficacy in clearing the room air (assuming air circulates around in the higher intensity area near the lamp, sort of like upper room UV). Or is the power too low to do much of anything at all?
@famulare_mike @Don_Milton 算术是否适用于这么小的设备，它在清除室内空气方面具有任何有意义的功效（假设空气在灯附近的高强度区域循环，有点像上层房间的紫外线）。还是功率太低而无法做很多事情？
