#1 should list only milestones or classics of flashlight history like the Mini Maglite, Surefire 6P, the first light with High a Power LED, the first 100 Lumen light, ... This should not be a endless list of lights someone just bought, it should end in a general consensus of the cpf members.
alright, here goes:
Surefire 6P, because I own several and it's a classic, the first "tactical" 2xCR123 flashlight
Surefire 8NX because I own one and it's a nitrolon classic
Surefire 8X because I own one and it's the 8NX's predecessor
Surefire 9AN because I own one and it's one out of 4 incandescent models with a high/low bulb, making it way cooler than all the above listed lights
Surefire 9N because I own one and I like its look more than the 9AN's, plus it's older
alright, let's go to some other brands:
Fenix P3D rebel 100 edition, because it was the first light in this class to claim 200 lumens output, and it was the first really expensive light I ever owned
Fenix T1 because I own one and it was (one of?) the first 2xCR123 tactical light(s?) with a high power LED, establishing what is now a whole category of lights that is now virtually unmanageable
Fenix TK20 because I own one and there's no other light like it as yet
Liteflux LF2XT, you guessed it, I own one
Eagletac M2C4 because it was the first light featuring two 18650 batteries side-by-side, and I own one
