The Chinese crap is very hit or miss with quality. I also doubt their 10000 lumen claim. My 2200 lumen streamlight is almost too bright. The streamlight leds are very bright and the quality is exceptional, plus they are easily to rebuild. Streamlights are also capable of being used as a defensive weapon in case of angry customers or wild homeless people.
I have been fortunate not to have lost any of my Streamlights and still have all four I've bought. They can take a serious beating and still work. I also like that the charger is the holder and it is always charged up. The cost isn't too much since this is my career and I use it all day every day.
The old non-LED one I never use anymore. The Stinger LED HL is almost too bright and hard on batteries but good for when the job calls for something really bright. I have two Stinger LED models. One for me and one for my tech. They are all engraved with my name and phone number in case they do get left behind.
At home I have some good rechargeable LED flashlights but they wouldn't hold up here for years on end like a Streamlight. I don't have Snap On wrenches at home either though.
I've hit rock bottom but I brought a pick and a shovel and I'm ready to dig!
I've had the rechargeable Streamlight Stylus for idk how many years now. Battery life is great the brightness is great, only problem is sometimes I have to tap the crap out of it, sometimes I throw straight to the ground. Other guy has a Coast stylus type. I was impressed with the brightness but it sees to not hold a charge for very long. My Streamlight can go all week without a charge.
