COSMOING High Power Red LED Flashlight Rechargeable, 300 Yards Red Flashlight IP65 Waterproof Red Light Torch for Night Observation, Camping

This is not the flashlight you want for astronomy. Its only got three settings; bright, super bright and flashing. You do not need flashing red for pretty much anything in astronomy, so its a pointless feature that you are forced to cycle through every time you use it. The dimmer of the two brightness's is still ridiculously bright when being used at a dark sky site. This could be fixed but would require modification to the circuitry, it would be better to just by a different flashlight. As it comes, it has a super bright hot spot in the light output, this can be fixed by removing the reflective cone, resulting in a nice even red circle, but again its still way too bright for astronomy purposes. Perhaps its a good option for some other purpose, whatever it is intended for, but not astronomy.

I wanted a red light flashlight for when I get up at night so I don’t have to turn on a light. But it’s too bright for inside! It would be great for outside, stargazing, etc. I found a red headlamp that’s better for indoors.

Very bright. Low on run time.

Returned it right out of the box did not work. I just got ahold of a bad one this time. Just didn’t have time to exchange it leaving on hunting trip next day

Does not hold a charge for very long. Light fades out quockly

I threw it away and bought a different red light flashlight. Dont waste you money.
