The little light with big performance!
Purpose-made for astronomy this handy dimmable red LED light can be used at high intensity for walking about then set to a lower intensity for comfortable use with an atlas or planisphere.
Uses only a 630nm red LED light so it will never accidentally blast you with white light. The intensity of the light can be adjusted from a soft red glow perfect for reading a planisphere or atlas to a bright beam useful in setting up equipment and walking around a dark observing site.
It can take up to 45 minutes for the human eye to completely adapt to darkness as a protein called Rhodopsin builds up in the rod cells. Once your night vision is adapted you might be surprised at how many more objects are visible, and how much better you can see details in faint objects. Unfortunately it takes only a few seconds of bright white light from a flashlight or cell phone display to deplete your night vision! The longer wavelength red light produced by the Night Reader Pro™ is detected by your eye's cone cells but does not deplete Rhodopsin in your rod cells. This allows you to read a chart or atlas and immediately return to viewing the sky.
Your neighbours at a star party will also appreciate your using an astronomy torch when setting up and moving around.
Chandler Night Sky planispheres are printed with a blue ink specifically selected to work with red light for ease of viewing.
Includes a quick-clip keychain attachment so it can be kept close at hand and the CR2032 alkaline battery is replaceable to reduce waste.
Made in the USA.

|Average Rating (5 Reviews): |Very Effective Red Light - Where to Place It?

Small but powerful red light device, with usual excellent delivery from FLO. The torch is of a key-ring design, and my first thought was where do I position it.
In the end, I found that the most effective position was on my coat zipper, which when zipped up, is situated just below my chin. Light intensity is nicely adjustable.
A good cost-effective purchase. Recommended.

Much smaller than I thought - about the size of a 50 pence piece but this doesn't detract from its powerful performance. Dimming capability very useful. Excellent for reading sky maps etc. Good value for and good service from FLO.

I'd read all the reviews I could find on red astro torches and was surprised to see so many negative points about most of the commonly available ones.
When I saw the description of the David Chandler Night Reader it sounded OK, but it looked too small and "toyish" compared to the others, and with slightly more involved operating instructions.
I took the plunge however, and ordered one.
I'm pleased to say that it works perfectly, and the single button operation is quite intuitive to use.
One immediately gets used to the instant full on/off and the gradual dim to on/off.
It weighs nothing around one's neck and is perfect for the job.

[Slightly fiddly to change cells and was delivered with an exhausted cell.]
