No, the light output of a lamp is the same, you’ve just focused more of it in a particular direction. It’s the same reason flashlights have a cone shaped mirror around the bulb. If it were possible to double light output, then putting a lamp between two mirrors would make infinite light.
This reminds me of a great demonstration of how directional antennas focus radio waves in one direction: https://youtu.be/lslHtCUSfN4
That was a cool vid- I don’t know much about antennas, so that was a fascinating watch. Thanks!
