2 Pcs Powerful Red LED Flashlight - Long Range Red Hunting Light Torch, Zoombale, Waterproof, Best for Astronomy, Aviation, Night Observation

Really bright. I learned in the Army that red light does not screw up your night vision. These flashlights are really bright. I put 3 triple A batteries in one and a rechargeable 18650 in the other. Not much difference in brightness. Thse will be an important part of my home security collection. Might buy 2 more for our cars.

Functionality of these red LED flashlights is great. Value for the money for two of these was right on point. I would definitely buy again. Zoom feature was awesome when trying to find rodents hiding in my fruit trees. Battery life was as expected and lasted quite a while.

The lights themselves are great for illuminating the dark without affecting your (or anyone else's) night vision! But, the cords that they ship with are really cheap. I already broke both and so I drilled out the holes larger to accomodate some gutted 550 cord... Problem solved!

Very good materials. Body of the flashlight is machined aluminum and weighs around 6oz. Comes with a 620nm/350ma red LED and PCB with resistors only and no annoying flashing mode IC so also opens the option to swap in other LEDs. Overall very good and should run for a long time on a battery.

These are great red LED flashlights, perfect for walking around at night at star parties or when setting up or tearing down your telescope and other astronomy equipment. I really like that you can focus or expand the area being illuminated. However, these are BRIGHT! Be careful where you shine these at night. You will ruin someone's dark adapted vision if you shine this light up at them. I keep it in the most narrow focused position and zoom out if needed. If you are looking to use this light to read star atlases, look elsewhere - this light is too bright and you will lose your dark adapted vision.

I bought these thinking they would be good for skywatching. And while they are *great* for walking to a site, they are actually so bright that they can kill your night vision. (Especially if your kid shines one right into your eyeballs.) But that's my fault, not the product's fault. It provides a ton of red light as advertised. The case and switch and sliding mechanism are all very solid. Pretty good quality device overall. Might be better suited for hunters or some other applications.

Hard to find. These are actual red LEDs and use a common 18650 battery. Most other "red" flashlights use a white led and then filter through red plastic, which is really not desireable. Have had these for a while and they just work great!

This is an awesome light if you want something to help your night vision, but also ignite the night. This would be great for camping or hiking, but if you're planning to use this for anything close range (like within 5-10 ft of your eyes), it is painfully bright. I haven't had it long enough to vouch for battery life. So this seems like a great flashlight, but unfortunately for my purposes (lighting a telescope viewing area) it was far too bright.

Good so far, really bright. I use it for fishing at night.
