case luminaire without a reflector and protective glass;
minimizing the weight and size of a luminaire;
quick connection and fixation system of a luminaire on a pole;
widespread use of pendant structures, light-weight poles, increasing the extension of consoles.
Design
reduction of installed capacity and the number of poles;
reduction of the safety factor to 1.1-1.15 in the design;
optimization of installations in terms of lighting parameters by the use of lamps with different light distribution.
Service
no need to repair a luminaire on the pole;
replacement of an entire unit or a luminaire with a working one;
the use of folding poles with maintenance carried out without an aerial work platform;
Economy
increasing the efficiency and reliability of lamps through the use of electronic ballasts;
preservation of lighting characteristics during the service life;
reduction of electricity consumption for outdoor lighting (up to 50%);
reduction of capital and operating costs for lighting installations (by 1.5-2 times);
Advantages of lamps with electronic ballasts of ЖКУ 33 type
Maximum degree of the optical unit protection from environmental factors (IP 67)
Reliable reproducibility and light distribution stability (light intensity distribution curve)
Optimum selection or replacement of light distribution depending on the specific task
Highest luminous flux utilization factor for street lighting installations
Electronic ballasts stabilize the voltage, reduces inrush currents, ensures the absence of a stroboscopic effect and significantly reduces the weight of the lamp
