High Power 1 Mode Red LED Flashlight, Single Mode Red Flashlight, Red Light Flashlight Red Light Torch for Astronomy, Aviation, Night Observation

I picked up this little red LED flashlight for camping and astronomy—and for such a compact tool, it punches way above its weight. The red light preserves night vision, so when I’m tuning my telescope or walking to the back of the campsite, I stay under the celestial glow without ruining my dark-adapted eyes. It’s rugged and solid—dropped it a few times into dirt and gravel, and it’s still going strong. With a beam that reaches around 150 yd/200 lumens, it’s great for illuminating charts, gear, or even signaling in the wilderness. Used it at multiple star parties: no glare, no complaints—just red glow guiding you under the Milky Way. Super strong in a tiny package that’s earned regular space in my gear pouch. Highly recommend for campers, amateur astronomers, and anyone who wants practical night lighting without the white-light blot-outs.

Anyone who has ever visited Zion knows how much emphasis the park places on reducing light pollution, as it's an international dark sky park. (Well, you would think anyone who visits Zion knows that, but judging from my recent visit I would argue that's actually a very small percentage. I digress.) Due to this fact, Zion recommends visitors bring red LED flashlights for nighttime use, to protect your night vision and prevent others from having their night views interrupted. In researching my different options, I came across the WAYLLSHINE High Power Red LED Flashlight. I found this flashlight to be a great tool - it's bright, only takes one AA battery, and is well-built. While others have argued that it's too bright, I found it to be perfect for walking around Zion at night. I prefer hand flashlights over headlights since you can control the beam a bit easier, and as long as you're not waving the flashlight all around it works to illuminate without overwhelming your surroundings. I also appreciate that it only has the red LED, so I could turn it on and off without having to worry about switching. I would highly recommend this flashlight, especially if you're going to be in an environment where night vision is important. Enjoy the stars while you can everyone!

My wife and I have recumbent trikes. one of the problems with a low rider like these is being seen. Most of the rear tail lights I have found are not bright enough for daylight use. and the ones that are bright enough are REALLY expensive. These (inexpensive) little jewels are VERY bright in the day and almost blindingly at night. I zip tied them to our racks using an old rubber handlebar grip cut to fit around the shaft (not blocking the cooling fins). I plan to mount them on a coil spring to mimic a blinking light. (possible maybe:) REVIEW: A FEW WEEKS LATER............After triking about for a while I looked at the now lensless capless flashlight. Apparently, these lens caps were not installed very tight. Good thing I ordered two more for the other side of the trike(s) This time I used Lok-Tight and tightened them as well as I could. Remember this, if you are going to install one of these little jewels on your bike/trike, it takes a beating back there. It would be interesting if the manufacture of these lights were to put out a light specifically for bikes, I for one would buy them. A FEW WEEKS LATER AGAIN. 14500 3.7V BATTERIES WILL NOT WORK. I have found that these little jewels do not like the 14500 cells. Mine worked for about 20 minutes and then started to flicker then die. I bought 4 of them to use as rear lights on my wife's and I recumbent trikes. (2 per trike) (very bright in full daylight) They are much brighter with the 14500 cells but then, alas, problems arise. The 14500 didn't ruin the flashlight, as I put standard AA 1.5V and they are working fine (again). Wrapping the battery in card stock to take up the slop will help stop the light flickering because of loose-juice in the tube issue. Great little light.....if ya knows the fix-it's.

Very bright red light in a small package at a great price. Works well when I am out with my telescope at night. If you find it too bright you can unscrew the front cover and put a custom cut semi transparent sheet in front of the led.

I bought this to spy on my pet tarantula in her home so I don't startle her with the overhead lights (allegedly they can't see red light). For such a small flashlight it's VERY bright and can be adjusted to focus more in a smaller area. It's also very tough, I've dropped it twice already onto a desk and it hasn't chipped or cracked. Quite a good little light!

A great red light flashlight I use for astronomy, plenty bright

Honestly, for those of us who use high quality expensive flashlights this will come across as cheap. However, it is functional and I use it when working with my telescope. If anything, it could be a little less bright. It gets the job done at a reasonable price. I may buy another.

Small, compact, and I was really impressed with how powerful the red light is. Perfect for hunting and finding my deer blind in the dark of morning.

Portablity and good brightness.

Veio com defeito que se tornou evidente e progressivamente pior: não acender com o apertar do botão e ligar somente com um chacoalhar. E o preço na Amazon está elevado. Contudo, o vendedor efetuou reembolso integral após uma explicação detalhada!

La intencidad de la lampara es realmente alta color rojo tal como se describe en la publicacion

Why did you pick this product vs others?: Amazing product. Bring enough in the dark to read star chart. Needs AA batteries.

Very Useful. But small torch with red light,
