I think it says the CoO is Taiwan, but could be India....the type is blurry.
Tis could be a future purchase, all I can recall finding have all been China made and they are quite frustrating to use as you have to shake or hit them sometimes or if you accidentally bump it the light will go out.
Best light ever had was a Black and Decker from AutoZone my Dad got me. It had a switch, up was high, down low, and middle off. The output looked the same on either setting and it would give bright output for hours on a charge. I now prefer battery operated.
Does this Delta light have any flaws? Maybe, light penetration, beam width or too dim.......do you have to cycle the lightswitch? Ive had lights that were terrible about this....you had to hit the switch to turn it on,hit it again and it goes to a different mode, then to strobe or dual lighting, then finally to off. Made me mad and I turned it on and set it on the sidewalk for someone to pick it up. I hated it so bad i didnt donate it to goodwill because i didnt want it to punish the next person. Sure, the LED will maybe last 100,000 hours but the button will be long gone before that.
