Upwards you got really nice suggestions. Still if you need 2 hours runtime on max, you will need big light to handle the heat well, so MF02 will be about the minimum. Alternative is Niwalker Vostro BK-Fa 30s, both rated 1.5 km and with coupon within your budget. L2 stock can also handle the heat, but it throws half of MF02. If you want to go zoomie, take Haikelite HT35, but it throws similar to Convoy L2 (specs were quite unrealistic). May be if you are able to mod it to dedome or change the emitter and bump the driver, it might fit the bill. Brinyte B168B with XPG2 and direct drive is also capable of 1 km throw with pencil beam in a compact package, but you will need spare batteries to cover these 2 hours. Stock Amutorch JM70 is also close to your requirements, way below budget.
