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.)
