Illumination for Stargazers. The Celestron Night Vision Red LED Flashlight’s two red LEDs produce just enough light for you to set up and break down your telescope, look at a star chart, read or write notes, change eyepieces, locate dropped items, or find a new position from which to stargaze, depending on the brightness setting, all while letting you maintain night-adjusted vision.

Variable Brightness? More Like Just-Rightness! As mentioned above, the Night Vision Flashlight has a range of brightness settings to best suit your needs. At maximum brightness, the light is bright enough to let you find dropped items, or assemble and disassemble your telescope. At medium brightness, you’ll be able to view a star chart without affecting your eyes’ adjustment to the darkness. At its lowest brightness, you get just enough light to see which filter you’re using or to determine an eyepiece’s focal length.

Power for Hours. This flashlight is powered by a single 9-volt battery that’ll last up to 12 hours at the highest setting and up to 300 hours at the lowest setting. This rental includes a 20-inch cord so you can hang the light around your neck when you’re not using it.

Might Help You Get Out of a Scary Dude’s House. Say you go into a guy’s house just to ask him some routine questions. He’s acting really off and you notice that there are a bunch of these weird moths flying around and stuff. Then he cuts off the lights! He knows where you are because he has those night-vision goggles, but what he doesn’t know is that you have this night-vision flashlight! Turn it on and get out of there!
