peg makes a good point. I would just run any light you plan on getting through the search function here on BLF, upper left of the screen. That feature alone can save you money and time.
The WowTac A4 is a really good thrower for the price. My review (and Amazon link) on that light HERE Had the Emisar D1 and Thrunite Catapult V6 in the video for comparisons also.
Do you have amazon credits or are you open to something ship and sold in the US? Because if thats the case, illumn.com with promo code XMAS2018 can get you the Thrunite Catapult v6 which is better than the other ones IMHO for $53. Comes with battery and onboard charging. Free shipping that AFAIR is 2 days.
