Wind-up lanterns? Should we get one?

[BigBadG]

i know wind-up is the green option but the guy in the shop says you have to wind them for 5 mins to get just 20 mins of light! plus they're quite noisy aren't they? will it wake DD? what about candle or gas lanterns? are they safe?

we have 2 wind up latern got at our local petrol station its def not noisy cost us 9.99 and has a option to charge it up before we go away via electric.
only needs a min of wind then 20 min charge
they give grt light of we use them in the awning at night and emergancy.
we was away fri to tues and were charged, they are dead now but needed about 2 times of a wind to get us through our trip i like them.
