Figured I would post on this topic because it refers to night lights. As I had mentioned in another post, I purchased a 1M Stanley spotlight at Wallmart for about $17. on Tues. Along with my Promos 100yd light I called in two coyotes that night. I had placed red transparent tape, used for putting over a broken taillight, over the Stanley spotlight. The tape filtered the light too much. Would only illuminate out to about 30 yards. Without the tape you could light up the inside of a tree line at at least 200 yards.
The next day, I removed all the tape from the spotlight and cut out a circle from the red transparent material from an EXIT sign. That night was very dark, and I went out back in the yard and tried the spotlight. Again, the material filtering the light way to much. I removed the material and simply took a red Sharpie, and colored the entire clear lens. I waited for it to dry and went out and tried it. From my house to the tree line is 65yards. Using the spot with the red Sharpie lens, I am able to illuminate a RED beam well into the tree line.
This is promising!! I was tempted to do the same to the Promos rifle light, for that has a lens like a taillight which only illuminates EYES, at maybe 80 yards??? The other night I could spot the coyotes eyes through my scope at about 110yards, but barely, and as soon as it turned it's head I couldn't see anything.
I plan to go out this evening to call with my nephew. I am going to place the Stanley spot on a broom handle as suggested by others on these forums. With someone holding the spot, I believe you could easily make out the entire body of a varmint at 100 + yards. I will let you folks know, how I made out.
