Compact Tube lights:
Sofirn Sp32A can be had for around $18 and they run 1300+ lumens on an 18650.
Nitefox UT20 is an awesome little light. If you PM Nitefox on here you’re likely to get an Amazon code. They have built in charging and are quite nicely made. Output is close to 1200 lumen.
My favorite small tube light is the Thrunite TC15 running over 2000 lumen with the XHP35 emitter and a good high drain cell. I love mine!

Slightly bigger C8 size:
Klarus St15 can be had for around $29. Dual switches and nicely made running the XP-L HI emitter, they are great all around quality light.
KD Litker (Kaidomain) C8.2 running the XHP35 HI emitter are advertused at 2,000 lumen though in testing they are really about 1800. Still an extremely well made C8 for $28.

Ever so slightly larger reflector than a C8, you have to try the BLF GT Mini. Ramping UI and awesome throw, they are very nice lights! Around $35 with a coupon code from Fin17

Don’t overlook the 21700 cell lights like the Rofis MR30 and Wuben A21!
