Thanks for giving some more detail.
There is
"sticky" post by a fellow named TEEJ that explains a bit about throw. Lighting up something that is 100 meters away can be much harder than you might expect.
Most CPF members have learned to take the ANSI FL 1 distance ratings with a grain of salt. Those ratings give the distance at which only 0.25 lux reaches the target, and this only in the brightest part of a beam. Slightly away from center, the lux can fall off rapidly. I take the beam distances given by a flashlight maker, and divide them by a factor of 3 or 4. Dividing by 2 gives the distance at which 1 lux arrives at the target. Dividing by 4, gives the distance at which 4 lux arrive.
If, therefore, I really needed to see across a 100-meter-wide garden, I would shop for a flashlight that is rated to throw 400 meters. To get that kind of throw in a zoomie set for flood is virtually impossible.
There are several popular "monster flooders" that run on 3x or 4x18650. They put out a wall of light at 3,000 to 8,000 lumens, but, generally, do not throw very far. Based on brute force alone, however, you may find that one of them can fit your needs.
The
Convoy L6 is inexpensive enough that you should consider buying one just to learn about what is realistic. You should be able to get one for around $55 USD. CPF member MHanlen tested the neutral-white version at 3,278 lumens, 70,011 candela, and 529 meters. Remember to divide the meters by 3 or 4 to get a realistic estimate of beam distance. The cool-white version is rated at 3,800 lumens, so it should throw a bit farther. The L6 has a relatively wide beam; it is not a dedicated thrower.
