Ledlenser® iL4


iL4 ATEX Flashlight (Zone 2/22)

As small and handy as a pen but as rugged and most importantly as safe as other lamps in the iL series: The Ledlenser iL4. Designed specifically for environments where explosive atmospheres such as flammable gases, vapors or dust clouds can occur for a short period. And yet it’s the cheapest lamp in the iL series. So not even costs will explode.
