Hi,
I do not have a DBS, but I have a Raidfire Spear....a close cousin to the DBS and I have had a C4 scorpian led. The DBS will be 30% brighter and throw MUCH farther than the stinger C4 led. The Streamlight Supertac has a much bigger reflector and will throw about as far as a DBS but it will be less bright since it is not driven as hard. I think the tightest throwing led out there is the Streamlight Firevulcan led lantern....big reflector....c4 led, but it is really a one trick pony of a light. It has a cool maxabeam like beam, but its sidespill needs to be brighter for my tastes.
