Of course, It does not help up close because it has a narrow beam, so does C8. your best bet would prbly be getting a soda can light with multiple leds and replace them with ir leds, the more the better. to get a flood down 150m you need a lot of watts, i do not know any formula how to calculate wattage for given distance\area, but judging by my 10w light, you’ll need 3-5 time more. imo. oh and mine is 850nm, if you use 940 you’ll need more power, prbly at least 2x as much compared to 850. it would prbly easier to build one from a scratch, than find a host that will fit your needs, how much time do you have, and how good are you with tools?
