Brightest I've seen are customized like this guy's:
But that Alta is a heavy-lifter type drone and maybe $18K too - and it's BIG too!
I've got the Lume Cubes on a P4 and they are good out to about 15 feet and need a high ISO for proper exposure and deal with the noise in post processing. Very purple too so you might need a #807 filter out of a Lee Zircon LED gel pack to balance them towards daylight. Your drone's lens is a wide angle so expect dark corners too with them, as well as a shorter flight time due to the added weight. They are better suited for seeing the thing in the dark at a distance than doing any photo work, imo.
