Think again. The emulation kits. emulation kits pay homage to classic designs in the lighting field. the most challenging dek to put together - definitely for the 'advanced' dek collector - dek3 takes the form of the famous tizio by richard sapper. all designer emulation kits run off of your standard 9 volt battery - one 9 volt battery should last for about 120 hours of use. all dek’s use led lighting giving them the ability to stay relatively cool and also allowing for operation around room temperature. led lighting has a life expectancy of five and half years of constant use. Arco lamps and more.... see if you can recognize more designers!! an earlier version than the now famous richard lawson's 9 volt lamp...
