UB,
Yes I think you'll need a hood as I did on mine.
What I did was took a pill bottle thats about 4 in long and the inside dia is the same as the outside of the 250, very snugly I might ad. I used electrical tape to darken it it could be painted and I make one wrap of electrical tape to secure to light.
Works great and it's cheap.
Yes the price went up for the 250 but to PPHA members Harrisburg Hunters and Anglers is giving a 10% discount.
They also stock extra batteries, the normal ones not the new ones yet.
I just got one of those NiteCore Headband for D10 Flashlight from lightjunction_dot_com on Ebay. $9.99 free shipping and it works great for the 100 as a scan light on top of your head.
Can't wait to get it in the field..
