I made my own 10,000 x2 lumen spot light by taking apart 2 headlamps with 7 LED lights in each. I took the light fixture out of the metal casing and replaced the heavy battery with a light weight 3S 11.1V. I attached the 14 lens in total to the light switch and attached the 3s lipo battery to the other side. It works amazingly well and is very light for its amazing capability. The headlamps cost 35 dollars each and the battery cost about 20 dollars. The light lasts about 1 hr total run time at full brightness. I suppose it puts a 20000 lumen spot light out. At 100 ft its like daylight. At 200 ft its like dusk. It still can see completely dark roads at 400 ft. It only takes off about 5 to 8 minutes of flight time.
