Honoson 10 Pieces Red Light Flashlight LED Single Mode Torch 1 Mode Scalable Red Lens Filter Flashlight for Night Astronomy Aviation Observation Beach Turtle Safe

These may look like every other "Mini LED Flashlight" but I can say they have the tightest tolerance compared to all the other ones I have tried. Plus the fact that these are a single mode (ON/OFF) light means they are far more reliable than those 3-mode (High, Low, Flash) flashlights. Produces a very vivid bright red light that lights up things all the way down my street. Only modification I have done for these is make a shim for the battery compartment so that the AA battery doesn't rattle around but that's an issue that all brands of this style of flashlight have and can be easily fixed by wrapping your AA with tape.

These are conveniently small and run off of a AA battery. For night time walks, they have been great for intermittent illumination. The ability to focus the beam is helpful when a higher intensity light is needed. Pretty remarkable value for the price.

As an engineer who has spent many years in the flashlight business, I am impressed with the the quality of this light.

Using it at night for hunting raccoons in my back yard, I have tape it to my Gamo Pellet gun.

This torch is really cool and handy tool for star Gazing nights. Small yet powerful enough to navigate the way. Do not cause light pollution or temporarily reduce vision like other flash lights.

For the price, I wasn't expecting them to be great quality but I'm impressed so far! I haven't tried dropping them in water, but I've used them outside in the rain and dark and so far they're working great. They're also heavier and sturdier than I expected so I highly recommend these and I'll definitely purchase from this seller again. P.S. don't hold me to it, but I think these are metal (aluminum?) NOT PLASTIC!

They came in on time, The worked great for the weekend and will be using them again.
