If I have learnt anything from horror movies, is that you need a thrower with the narrowest beam, such as an Acebeam W30.
mid range flood light is what you need, compact and easy to carry is important.
i would carry Emisar D4s 
and have disco strobe with ghost 
I laughed so hard. The FLIR replay, tears in my eyes.
Being an urban explorer, I just use a selection of Convoy S2+ (in different tints) and a KDLITKER E6 (with various colour P60 drop ins) for exploring.
Where do u go? Is it legal to go into the property?
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.
Sounds fun. Wonder where can I go in California to explore.
You are in a fantastic spot for exploring abandoned mines! TRV Exploring, this guy has probably been to them all.
By its nature, Urban Exploring is visiting places you shouldn’t be in. So in most cases the locations are illegal to access.
I’ve visited many large stormwater drains, mental asylums, bridge rooms, and various abandoned properties.
Spooky.
