The problem is this: The sensitivity of human eye is the logarithm of photon count.
For example, if you have a LED and you reduce the current by 50%, then, without direct comparison, you would not see a difference in brightness. Also, in videos, the camera will change the exposure, if brightness changes, and this has the same effect. It is not possible to estimate the power from the visual experience of brightness. Without power measurements these lamp and LED demonstrations are meaningless and misleading. Added to this, we have resonance transformation effects, and this makes precise electrical power measurements difficult if not impossible without very expensive equipment. Peter
