I have a Bushnell 4200 2.5-10 with the firefly. It comes with a little flashlight that is less than useless. A standard aaa maglite, puts out almost no lumens. I use my Petzl 4 led headlamp to shine into the scope for a few minutes just before sunset to energize the crosshairs. Seems to keep them bright for a little less than 10 minutes. Considering that last 5 minutes or so of legal post-sunset time, I suppose the lighted reticle could make a difference. Hasn't for me so far, though.
