Weltool M6-RD Red LED Dark Adaptation Penlight for Pilots Viewing Navigation Maps, HGN Tests, SFST and ARIDE to DRE Evaluations，Pocket Pen Light with Clip for Doctors and Veterinarians

Tarantulas do not see red light. This is perfect to deal with my tarantulas without bother them, see where they are hiding in their terrariums.

I can find things in the dark

After my other light disappeared, bought this. It is much brighter than my mag light, and has a narrower beam. They only problem is the Fish and Inverts can see it, not the fault of the light, though. I just have to be quick.

It’s small, compact, and easy to carry as a penlight for very dark situations. Specifically if you’re trying not to blind yourself or others around you. It does come with batteries, they are easy to replace, and our size AAA, which is convenient and not like a strange battery size.

This is a great product but is too bright for doing darkroom examinations as done during a DRE examination.

I use this for travel mostly and its red light is perfect for not waking people around you on flights, or fishing trips, or digging through your friends belongings ;) Easy to use, feels sturdy, very happy with the purchase.

I was hoping to use it to assist with phlebotomy, but I actually feel veins much better than can see them with this light. It shines through my sons palm and, I guess, it can be helpful in pediatrics. I will keep it just in case, but my hopes of using it in venipuncture are very low. On positive, it feels very durable and I like that it uses standard AAA batteries, which came with the flashlight.

Very sturdy, long lasting on 1 AAA battery. Gives a very precise round light pattern. No adjustment to the light cones. I use for night adapted vision in my astronomy hobby Pick clip to prevent loss.
