I had the black one which is the same thing and gave it away to a family member after a few weeks. It wasn't powerful enough to replace a 2-5 watt incandescent light. IMHO, there are better lights for $140. It gives a bluish-white, even and rather pretty, but diffused beam. It has excellent runtimes and it is very durable, and respectable emergency light, but be sure you really want such soft diffuse light before you commit to it. Lumenwise it's nothing great. Not many app's are best served with such a soft output. For illumination there are plenty of better alternatives, some for less than $50, and for professional or emergency uses there are better choices too like a Surefire M2, 6P, E2, Streamlight Stinger, the Lightwave 4000, the PT Surge to name a few. Most of these cost a lot less and all of them put out more light. With a little hobby skill you can also build a better LED flashlight. Several members have also built 36 LED flashlights from the Energizer Double Barrel. I had one and found it superior to the Trek although it wasn't cheaper. I would say if you really like LED lights try the Lightwave 4000 or 3000 first and see if you like them. The Trek is pricey because it uses an expensive bulb but that bulb is not superior for very many applications.
