hi,i am looking to buy either one really bright lantern possibly gas,or two decent led lanterns. it/they will be used to light up 2 20x20 white painted half pipe bowls at a local skate park.so optimal lighting is what i will neeed.i was leaning towards two rayovac 300 lumen lanterns. based on the reviews it looks i might have to opt for a coleman twin power instead? or should i go with a high powered gas lantern?i understand that if one lantern were to fail i would be left with 0% lighting in my case.they will be used in an open ventilated area.
