I am really trying to go the 'environmental' route with, at least, campsite lighting.
I had long ago abandoned incandescent flashlights, in favour of LED [CREE type] lighting. These work great as flashlights; they are very bright (brighter than most incandescent-based flashlights), and last a long time.
However, for widely dispersed lighting (aka lantern), thus far, I have been very disappointed. Last year, my wife and I took along the Coleman Micro Packer LED Lantern and the Freeplay Indigo Self-Sufficient LED Lantern. Although they appeared to pass our in-home testing, they fell far short of our expectations while camping. Even with both of them running, there wasn't enough light to wash dishes and clean up around the campsite before heading to bed.
Today, we were looking at the Coleman Rugged Personal-Size Lantern (model 2000000839 - what kind of model # is that?). This is the one with the 7 watt fluorescent bulb with an output of 140 lumens. They make a big deal out of 140 lumens... BUT WHOOPIE! 140 lumens is roughly the output equivalent of a 10 watt incandescent light bulb.
Practical dispersed lighting isn't achievable until about 400 lumens (or about the equivalent of a 40 watt incandescent light bulb).
It seems that my only choice is a naptha fuel based lantern and ensure that I purchase non-radioactive mantles (the manufacturing of these mantles have created environmental disasters). I am not interested in Propane or other disposable cylinder based lighting because that is just plain wasteful. I do not understand their popularity.
Your thoughts are welcome.
