Working in outdoor encampments over the years, I have witnessed two approaches to lighting. One approach is to try and banish the darkness with powerful lights that illuminate your full field of vision. The other approach seeks to provide sufficient light to to provide orientation and safety but to allow our eyes to adapt somewhat to the darkness.
There are pros and cons to each approach but unfortunately, they do not tend to work well together.
Pressurised lanterns provide clear, bright and relatively white light. They represent the technological pinnacle of liquid or gas fuelled lighting and if I was receiving surgery in a remote field hospital I would be very grateful for that technology.
A ring of lower powered lighting, such as traditional hurricane lanterns, placed around the edge of the fire circle extends that pool of light considerably without significantly disturbing that dark adaptation. A few lamps extending further into the camp, nearer to people's tents, provides orientation and normally enough light to navigate trip hazards such as guy lines.
People that require a bit more illumination can always carry a hurricane lantern or similar with them but because it is nowhere near as bright as a pressure lamp it won't dazzle everyone else in the camp.
So it is clear that a simple choice has to be made between bright and low lighting. Either we flood the whole area with light and people have to carry lanterns or torches with them as they move around or we adopt the low light approach.
Shining bright lights around in amongst low light camp illumination disrupts everyone's dark eye adaptation to the point that the less powerful lamps cease to be of much use.
If, as I hope, we adopt the low light approach, we can always resort to torches or head lamps for brighter lighting in an emergency and a small torch can easily be used discretely for rooting through a bag or box without disturbing the whole camp when needed. Low powered red torches can even do it without wrecking your own night vision.
One additional point does need to be made though. Naked flames in tents present a clear and present danger to life, limb and property. That does not mean they should be banned, as they have been used successfully in such situations for thousands of years.
It does mean that caution is needed. A lantern is much safer than an open candle but all lights need to be situated in places where they are well away from canvas or other combustibles. Attention needs to be given to what may happen if a draft or gust of wind moves either the light or combustibles near to the light. Things get bumped or knocked over all the time in camping environments. Put some serious thought into what the consequences of that could be and place your lights accordingly..
I would go so far as to recommend a two metre gap between tents and it would be very wise if all tents had a fire bucket or extinguisher of some kind near their pitch.
The only time I have seen a tent fire in a living history camp was due to parents leaving their children unattended in a tent with open candles. I will let you draw your own conclusion about what happened in that incident. Fortunately no one was hurt.
An LED. Head torch is also a terrific innovation when you have your head under the bonnet of a vehicle trying to determine why it has refused to move any further down a dark lane.
Under such circumstances I would fully embrace these marvels and sing praise to their inventors. However, in a communal situation, where people have differing priorities, they can also be a curse.
Night vision is a complex subject but in overly simple terms, a few seconds of bright light causes a dramatic reduction in the eyes ability to see in low light for up to thirty minutes. That means that although that wonderfully bright lantern or head torch allows you to see where you are going, carrying it into an area where other people are working with dark adapted eyes will blind everybody else for almost half an hour. Not generally popular and not very thoughtful.
Given that many people in the communal area at night will be socialising around a fire, they will obviously not be relying on full night vision but they will usually be at a halfway stage, adapted to relatively low light.
They can usually see well enough for most tasks around the fire and as they step away from the pool of light around the fire circle they can often see vague shapes around the camp because they are partially adapted to the dark.
According to the book of Genisis, it was on the first day of creation that God said "Let there be light." Apparently, light must have been considered a rather important thing when creating a new world then so I think it is worth discussing as a topic on it's own.
