The Thermacell Mosquito Repeller Scout Camp Lantern effectively repels mosquitoes, black flies and other biting insects by creating a 21m2 zone of protection for bug-free comfort. Its bright 220-lumen light runs for 10 hours on the highest setting, making it a great addition to the serious camper or caravaner's set up. The unit will operate for up to 40 hours on it's lowest setting (55 lumens) and features a removable base with hanging hook to allow the light to be used independently of the repeller. The Scout Lantern runs off 4 x AA batteries which aren't included. Make sure you take this along to your next camping, fishing, 4WD or caravan adventure, for an unbeatable duo of insect protection and ambient lighting.
