Okay boys and girls, I have a super nerdalicious addition to your pocket protectors. The streamlight penlight is the BEST penlight I’ve encountered and you know how much I love a good pupillary exam. It’s strong (LED light), slim (the size of a pen), affordable (about $13), comes in neato colors (like the 80’s throwback gold which I own) and the best part: it only lights up when you press the top button. Therefore, it doesn’t get left on inadvertently for you to later discover that the battery has died (RIP old penlights of mine).
For non-pupil examiners: consider this little gadget your affordable, spare flashlight!
