There's no end to the cool, informative things available on the web. Take, for instance, ETC's new Source Four luminaire ‘mini-site' www.etcconnect.com/minisite/sourcefour/index.html, featuring everything you need to know about the popular lights, in an interactive graphic mode.

The mini-site's Home page gives viewers a concise end-to-end tour of the Source Four - all of the unique physical features that make it a leading fixed focus spotlight for entertainment and architecture.

The History page tells the chronological story of the Source Four family - when each light was introduced by ETC and the technical innovations that have made it an award winner.

The Photometrics page is an invaluable tool - just click on a lighting-throw distance, choose a Source Four luminaire, pick a lamp, and see both the field diameter and the footcandle / lux readings for that luminaire at that distance. A handy short cut for lighting designers, a learning tool for newcomers.

And finally, people who have had a real-world demo of ETC's new Source Four EDLT (Enhanced Definition Lens Tube) option know that you have to see the new lens tube in action to appreciate its image-sharpening power. The mini-site's virtual demo shows the before and after ultra-crisp gobo effect made possible by the EDLT. (And make sure to look at all the images - there's more than one.)
