I have been very vocal about this... Nice to see I am not alone. IMHO bright lights used incorrectly can hinder and impair vision more than improve it.
This is where I am pretty happy with my lights. Though I have a lot of lumen available I also have low modes on several lights.
For camping I have:
4D Maglite with Malkoff - great floodlight, lights up a huge area really brightly, no low mode, wont get used much.
Jetbeam Jet-I IBS with Q5 - I have programmed the first mode to be a very low (about 5%) output - fantastic light, will probably run over 20 hours on a 14500 or AA - Will be one of my main lights on camping trips.
Fenix L2D with Q5 - will run for over 40 hours on low, with loosened head it starts in low on the first click, another great light for camping.
Olight M20 Premium - will run for 20 to 70 hours on low depending on what type of batteries I use, remembers last setting so I can use it on low all the time.
For camping I currently have 3 lights that can come on in low mode with no night vision destroying modes to cycle past. The low mode also gives the added advantage of fantastic run times which is not a bad thing at all when camping.
On the way I have 2 more great camping lights:
Jetbeam Jet-I Pro EX - I will program that with a very low mode on first click and with 2 x AA batteries that will run for well over 40 hours.
Jetbeam Jet-III M - 2 modes selected by twisting head - full or programmed, I will set the programmable mode to very low for camping (I can always reprogram it for something else when using it in other situations). If I set the low mode to around 5% then it should run for 70+ hours on its batteries (even the default low on the Jet-III is good for almost 40 hours).
Both of my new lights will also be able to turn on straight to a very low mode. That will be 5 lights capable of making light that is good on my eyes and good on the batteries on the first click, all 5 are also capable of turning on straight to maximum output for blinding light. It's that versatility that is so great with modern lights, great for security but also great for camping - I can use these suckers anywhere and anyway I want!
Any flashaholic going camping should bear this all in mind and don't just take your most powerful lights with the best throw or flood:tsk:, take some good low mode lights with long run times :twothumbs (and of course fully charged batteries + spares). It is also handy to be using a low level light when the smart alec starts telling everyone about how much brighter his light is - "hmmm, let me just switch this tiny little AA (actually running a 14500) light to full" -
:nana::hahaha: If that doesn't do it then I'll go grab my Maglite 4D with the Malkoff drop-in!
