"Talk about having a secret weapon in your back pocket!" says one of our judges about the smart little app, Lighting Handbook, developed by freelance production technician and lighting designer (and now iPhone app developer) Andrew Derrington.

Basically, this app for the iPhone and iPod Touch holds a wealth of information about moving lights, LED fixtures, scrollers, dimmers, and more DMX fixtures."It’s such an amazing reference tool packed into the communication device that is always on your person. This software is arguably the most valuable reference tool I’ve utilized in the last decade," continues our judge. Another calls it a "very handy reference guide of moving lights for handheld devices."
