I don't know if it will out throw the dereelight, but it will out throw the wf 500 by sheer brute force, so more than likely it will also out throw the dereelight. It's not junky at all, some of the similar mte P7's were junky but aurora I think is better quality than ultrafire. About on par with romisen. I took mine out in the dark and it could easily light up a tree about 300 feet away. But flashlights aren't all about throw, the P7 has such a nice and smooth beam and lots of spill. This makes the light really useable for lighting up dark areas.
