Den Haan Rotterdam - established 1922
All lacquered DHR lamps are for indoor use!
All Den Haan lamps made of brass or copper, polished and lacquered, are suitable for indoor use only if nothing else has been stated. To prolong their lifespan Den Haan recommend their lamps be waxed with pure bees wax once a year. Of course you can use the lamps outdoor when you are outdoor yourself but remember to store the lamps in an indoor dry and warm environment.
