Query: as a nurse

Well, the light on this one is so strong that when I checked my patient's pupils, they scream like heck. So, I just use this penlight to the big trauma patients and those who are severely neurologically compromised, because a sluggish vs. brisk response might make a huge difference to these patients. I've had this for 8 months now and it is still going strong.
