Arbitrary I know but I have 3 lights that I like and would be OK if that's all I could have if that was necessary. There are some that are more general purpose and therefore I should use them more...but I don't
I have 3 that I just like
Mine are a Zebralight H51f just because the resulting light is so pleasant to be around and the light itself is uncluttered, the ITP A3 (3 mode) and a 35mm diameter (18650) aspheric that I modified.
A Thrunite TI (when I do use it and none of these 3 are EDC) is worn necklace style and tucked into the shirt so it's just there when I need it.
An aspheric "light saber" which is small enough to be handy on occasion (and it's fun). I spotted a family of raccoons transiting my yard with it tonight!
None of my favorites are high lumen output lights. There are no strobes in this bunch (actually hidden in the H51f I guess but unused). The aspheric is single mode. The TI is usually used on low or medium.
Sometimes my Proton Pro might be used more often than the aspheric thrower just as a walking around light. I'm breaking my own rules as that's now 4 lights
Do you have a few favorites that are favorites mainly through the process of having other lights until you figured out what works best for you. List a few and maybe mention why in particular these are favorites.
