Does anybody read these? If any of you are reading this, shoot me a email / DM / tag me with "pineapple".


The Lighting Nerds! We're still around. Thanks so many to the many, many people who stepped up in to say that they'd be happy to host a show with me, it felt really good to find out that people still care and want to help. Introducing a new host who will be around (I hope!) a while, it's Alex! From Australia. You might know him as the guy who makes the Console Training videos on YouTube. He's also a Lighting Nerd.

    • MAC Encore line of LED fixtures from Martin.

    • GLP JDC1. Can we come up with a different name? Cool light, though.

May one day people all over the world not just tolerate but celebrate different faiths and cultures, and have their greetings accepted in the spirit they were given, without fear of being mocked and laughed at by those who lack understanding.

Between having a nasty upper respiratory infection (just what you want when you're a podcaster) gigging over New Years, and moving to different houses, it's a wonder we're only fourteen hours late on this one. Anyway, fresh off the presses, it's Lighting Nerds, Episode 005 folks. In this edition:

Short aside folks: in this episode I say, in reference to the ETC PARNel that it “is a Fresnel optic in a PAR housing.” This is a mistake, what I meant to say is that the optics of a PARNel are roughly equivalent to the result that a Fresnel lens gives you. Clearly the PARNel is not a Fresnel optic. That is all.
