long throw tactical recomendations high lumen

hi

im hoping a few of you can help.i'm looking to purchase a long throw tactical led.tactical so that i can mount it easily



i have a tiablo ag10 which is great but i need more range and a brighter light.

the spot needs to be tight,but it can overspill a bit



it must be led with no warm up time



i have searched the web and am having dificulty. should i stay away from the ebay chinese flashlights or are they ok.

1. do they overplay their lumen ratings,

2. are they safe



or is it best to stay with more expensive bu well known brands



any advice welcome

thanks

matt
