There are different types of headlamps available in the market which come with varieties of lumens power. The range may vary from 50 to 500 lumens. If you are buying a headlamp for camping purposes, you can go for medium-ranged lumens, like 100 to 250 lumens. Such lamps can only brighten the camping ground and your activity area and won’t disturb others with the bright light. But, if you are planning to explore the camping ground and forest, especially at night, you can go for more lumens to create a brighter light.
