Fun fact: I play one of my games with a mod that adds a flashlight. You get the options of incandescent (kinda dim, wide spot with no spill, warm), halogen (less warm, longer reach, floody) and LED (perfect daylight-like tint thrower with a tight spot and wide bright spill, like a BLF GT Mini). Guess which I use to keep the atmosphere
I would use my Acebeam L30. Bouncing it off the ceiling lights an entire room up with plenty of light to identify anything and its got range to light up any house. And if I thought there might be danger like when I explore abandon mines here in Nevada I use my L6 or X45. Bears mountain lions rattle snakes scorpions skunks and vagrants will put a damper in you explorations. I had two small scorpions fall on my legs once and it freaked me out lol, it was almost a very bad day but it was colder out so they were very dormant and slow moving. As a kid I would run around and explore abandoned military bases in Washington state along with coal mines, very dangerous but fun.
