I use the Eastman LX-5 with carbon coating that's supposed to recharge in any kind of light. Seems to work just fine and is completely black inside. For Bowhunting I was looking for a blind large enough to shoot out of that I didn't have to stick my arrow out the window and the Eastman is plenty big enough for that. A real plus when buying a blind is getting one tall enough that you can stand up in without having to bend over....and the Eastman is 6 foot at the center so it fits my needs just perfect. Hope this helps....
