FOREWORD
Den Haan Rotterdam is a family company respected in 1922. Started as a small tinsmith, it has evolved
into a globally respected producer of navigation lights, searchlights, air horns and a wide range of nautical
lamps made from copper and brass. By introducing products with advanced LED-technology, DHR has
safeguarded a visibly safe future for marine vessels in all weather conditions.
With the addition of the brand new 420RCB searchlight, DHR completes her line of searchlights with a
product designed for heavy duty applications. A perfect solution for tugs, workboats, cargo vessels or even
larger inland vessels, this type of searchlight is easy in use and made for the job. Installation is straight-for-
ward, due its well-thought mechanical and electrical design. As it is the feather-weight among the compe-
tition, positioning and mounting of the 420RCB will be done in an instant. The effort of any maintenance
actions, is reduced to a minimum
DHR believes that the 420RCB-series certainly adds value to the shipowner. An impressive optical system in
combination with a robust and compact design, makes it a unique, distinctive and high-quality searchlight.
