I have a gift card for Amazon and was thinking about getting some light for the field. Any recommendations?

I finally tried a headlamp with a red side. This one.






  • Battery last forever.
  • It has both red and white light and separate buttons for them (You just have to remember which button is which. lol.gif )
  • I bought another because it last so long (4 or more nights) I forget to charge it so I keep one on standby.
  • Hands are free.



  • With gloves you have to take them off to turn it on and off. So I don't bother to turn it off since it last so long I just leave it on.
  • It has has a flashing mode which is a pain at times.

For the past two years, I've used this:




...and this:




...which does fit the LD12.


What's really nice, is that when used with the rechargeable battery, the Medium setting (30 lumens) is good for an entire three-night session, if used "normally". Under dark skies, with full dark-adaptation, it's also somewhat bright, though... so I very rarely use it, unless I'm looking for something on the ground. The Low setting on the LD12 is wonderfully dim however (only 5 lumens), and on that setting, my dark-adaptation is perfectly preserved, and the battery charge lasts for many days of normal all-night use.


I've used dozens of inexpensive and moderately-priced "small" LED flashlights over the years, and without exception, the switches on them have invariably failed within six months. I now have four Fenix lights: one LD12 and three smaller and less-expensive E12s -- one of which is four years old, and is used many times every day -- and all of them still perform flawlessly. And Fenix flashlights have a "limited lifetime warranty".


As in most things... you get what you pay for.  grin.gif

I've been using one of these for 20+ yrs.  The dimmer feature is nice.  Neither the red nor white settings are extremely bright, but that is probably a good thing.

This one is red only:

I guess this is their latest version:

They are expensive compared to other lights, but considering mine has lasted 20+ yrs, I can't complain too much.  I think I've taken it apart 2 or 3 times to clean out the pocket dust, but otherwise has been pretty much flawless.    (On the other hand I have a box full of dead $10 to $30 headlamps -- most of them seem to fall apart after a couple years.)

Here is a tread on CN that has nearly 300 posts about red lights for astronomy related activities, it should answer all of your questions and gives lots of recommendations for products:




In any case, I wouldn't recommend anything that can't use rechargeable batteries. Otherwise, you could end up spending a small fortune on disposable batteries. Buy a few sets of Sanyo Eneloop batteries and a good charger and it will pay for itself in the first year or two of use.
