Wow, I wasn't expecting so many responses to my inquiry. You guys are awesome! I will certainly look into the suggestions made. However, is there any way to see what the projected beams look like? I've seen pictures where they point the flashlight at a wall from a few feet away so that you can see the light patterns. Is there some kind of resource out there that shows this for a bunch of different flashlights? Some units that I've looked into do show such a demo, but some units don't show it.
My previous post (#7) might have gotten overlooked. I'm being "moderated" until I have a post greater than 3, and it took all day to have my post appear. (to whoever is doing the moderating: I'm not ragging on you... just doing some clarifying
)
One thing I want to clarify is how I use the light. I'm checking to see if the patients are breathing. The most effective way that I've found is not to have a bunch of general illumination in the room. It's easier to cast a brighter, narrower bean at a slightly downward angle from the corner of the bed. It's easier to see the motion of the shadows cast by the rising and falling chest. It's harder to see the actual motion of the person's chest. That's why I was asking about a flashlight that has a narrow beam with a hard edge... because I'm pointing it at a low angle from the foot of the bed toward the patient's face, and I don't want ANY light to go above the person's neck.
Thanks for all your input!
