Avoid the temporary vision impairment that comes after using a bright white light with the SL-33 RedSight Pro Red LED Flashlight from Carson Optical. This compact flashlight employs nine red LEDs that preserve night-acclimated vision and cause less disturbance than white light in dark settings like the theater. It's handy for reading star charts when using a telescope or for working in a darkroom. The light has a glow-in-the-dark handle so it's easy to find and comes with a carabiner clip for easy portability. The SL-33 RedSight Pro runs on three user-supplied AAA batteries.

Carson SL-33 RedSight Pro Reviews
This, and the UV one, failed in short order
By Oliver
Rated 1 out of 5
Date: 2026-06-05
This one failed within some hours, perhaps the 18" drop did it... but, um... that's not far... and it wasn't bad, didn't.... The UV one failed after light use over a couple months. Carson = on my garbage list.
A much-needed accessory
By John

For consulting star charts or changing eyepieces, a red-light flashlight is a necessary accessory for every skywatcher. Its red light preserves night vison and is bright enough to read by. Its pushbutton on-off makes it easy to use and the glow in the dark feature makes it a snap to locate when you need it. Clear Skies!
