..The Turtlelite and/or the Dorcy Coolbeam? First to make an LED actually be able to THROW!!! I sure remember these, I bought one as soon as it came out. Anyways, do you also remember the way they modified those little 5mm's to make them more difuse and throw better? They ground down the LED a bit to make the angle wider and etched a sort of radial, geometric design on the LED's epoxy surface. I was wondering, what if that same radial geometric etching technique were to be used on a Luxeon High Dome (Lambertian)??? It wouldn't need to be ground down as the angle is already wide enough, but could it possibly increase the throw even more when used in a reflectored design? I've tried sandpapering white 5mm's before and it doesn't even come close to the effectiveness of the etching technique...
