Don't shine the light directly at them until you are ready to shoot.
3 million is pretty bright, especially for a Qbeam. We run 400,000 on our BigMax Qbeams and it's more than enough for several hundred yards.
Are you using red or white light? Either way, I think you're probably burning them way too early. In reality you can use the brightest light in the world as long as you just keep them in the halo until it's time to pull the trigger.
