    JIM! This is another really great video. I have a suggestion, one that will benefit you as well as the rest of humanity! Slice out the bit about light bulbs and make it its own little video. If you do that I can share it on Facebook with my idiot friends who think LED bulbs are a conspiracy to render them impotent, cause annel itching, cause body odor, are fattening and allow big brother to spy on them. Help stop the madness!

      Too funny! Yes, there are some gullible people out there. My new years resolution was to be less polite to these people. Send them this time stamp: th-cam.com/video/tviuUPIyzHE/w-d-xo.html

      @@bigbadtech The math on the LED efficiency example is wrong. The LED bulb is 96% efficient, not 9.6%!!!!

      2.4/25=.096, .096*100=9.6%, a 96% efficient 25W bulb would produce an eye searing 24W of radiant power.

      ​@@bigbadtech Ahh, I see it now. I was reading the graphic as 24 not 2.4
