Olight Perun 2. Yes, it is expensive, but we'll worth it for a job where I use a flashlight all day every day. I can slap on the headband for crawl work, or clip it on my belt for use in and around the house, and I can very easily charge it in the truck between stops with the magnetic charging cable.
Honestly the reason I recommend it so much is durability. This is my second Olight, and also the second time I have left one of their lights outside at a customer's house. Both lights survived an entire month of rain outdoors, and still work just fine.
