(Note: You will have to change the batteries a few times within those 100k hours). LED lamps are durable, efficient and energy- saving, which makes them both environmentally friendly and a cost-effective solution for your camping gear 3 LIGHTING MODES: The lamps have three flash modes - High, Low and Flash and they work both folded and unfolded. COMPACT & LIGHTWEIGHT: The diameter of each lamp is 3.35 Inches (8.5 cm). They collapse down to 1.97 inches (5 cm) and stand at 5.1 inches (13 cm) at their unfolded height. The lamps weigh 200 grams (or 7 oz) each with batteries and 130 grams (or 4.5 oz) without. The light weight and small size makes the lamp easy to bring with you wherever you go, and the smart handle makes it suitable to carry by hand or attach to a bag.
