I have the standard Stinger DS LED and decided to try the HL version. The light is noticeably brighter with the HL and is probably worth the price difference. Unfortunately, the charger that came with my light had a noticeable loud hum when charging. My first call to Streamlight resulted in being told to return it at my own expenses for repair (I had the light less than a week). I called again and received a better customer service representative. She said she would send a new charger but recommended returning the whole unit and she would provided a return postage label. She promptly provided the label and the light has been returned. While it certainly is not the fault of anyone specific, I always find it inconvenient for the customer to be the quality control agent. Between phone calls, repackaging, and making a trip to UPS, I spent hours of my own time to return the unit. Hopefully, this was just an isolated example as the light is great.
