Ok, I did a very controlled experiment to see which is the brightest, a Fenix P1D (Cree XR-E LED), a Dinotte 5watt (5 watt Luxeon) or my Cateye Doubleshot (2 x 3 Watt Luxeon LEDs). The "experiment" consisted of me turning on each light in my basement and shinning them on a wall (very controlled experiment!). The Dinotte had the widest beam followed by the cateye and then the Fenix. The least brightest was the Dinotte followed by the Fenix and then the Cateye. The cateye was only slightly brighter than the Fenix but it had more spill compared to the Fenix as well. This was only done at a distance of about 12 feet so I couldn't measure throw using this "experiment". I have a feeling that the cateye has the furthest throw but I will try that later and let everybody know. Hope this helps.
