Review - Atom A0 with Red LED

The Atom A0 is a
great keychain light.
I reviewed the Preon P0 last March. Since then, I have had almost a full year's worth of experience with the flashlight and am still very impressed by it. I still keep it on my keys and it has come in handy a number of times. If you would like to read more about the flashlight, please click HERE to read my blog post about it.

FOURSEVENS has listened to customer requests and now makes a Preon P0 (now called Atom A0) with a Red LED, and that is what we'll look in this review.

The Atom A0 comes in the exact same form factor as the Preon P0. It is 2.2" long, 0.5" in diameter and weighs only 0.8 oz with the included AAA battery. This size is only slightly larger than the AAA battery that it uses.

The A0 has an integrated magnet in the tail.
The body of the light is made out of stainless steel and comes with an integrated magnet in the tail. This allows you to stick the light to any ferrous surface for hands-free lighting. For attaching to a keychain the A0 comes with a small keyring.

The difference between the P0 and A0 is that the A0 comes with a CREE XP-E Red LED. This LED also has two modes, just like the P0. The first mode is low, and emits 0.5 lumens. Turning the flashlight off and on quickly by twisting the head changes the mode to high, which emits 15 lumens. This is less bright than the P0, which has a maximum brightness of 25 lumens.

Why a Red LED?

The Atom A0 comes with a Red LED, as can be seen here.
A red LED makes a lot of sense for a flashlight. Red light preserves night vision better than white light. This makes a red light ideal for star gazing or tasks where you need brief illumination, but still need to see in the dark. I have tested this and found it to be true myself.

The red LED isn't as bright as the white LED that the P0 normally comes with, but it's still adequately bright on high for seeing things in the dark. In fact, the red light gives a very interesting effect and is a neat flashlight to have, especially if you're a flashlight enthusiast.

The Atom A0 by FOURSEVENS is a great flashlight on its own, and with a red LED becomes even better for select applications. If you enjoy flashlights, this is definitely a light to check out.

  3. Personally, I prefer white light, even for night vision. Nevertheless, I have heard and even read in your post that red light has its advantages. Therefore, I will give it a try when encamping next time I am outdoors. Also, check out some remarkable LED flashlights here: http://survival-mastery.com/reviews/best-led-flashlight.html

  5. I'm getting myself a new tactical flashlight this week and as always, these are my top features to consider: longevity, lumens and being water resistant. So far, there are a lot of products that fit my criteria, although I have one more thing to consider - brand. Of course, I only purchase brands that are reliable and has been in the business for years. For list of the top brands in the market today, read the reviews in this site, first before making a decision: http://backpackingmastery.com/top-picks/best-tactical-flashlight.html
