Opšte karakteristike metal-halogenih sijalica:

• Extremely high light output 
  

• Best color rendering 
  

• Light output three to four times higher in comparison to filament light 
  

• Light is generated via an arc between two electrodes 
  

• Spectrum similar to daylight (between 4500 and 6500 K) 
  

• Constant color temperature and color rendering behaviour over the whole lamp life 
  

• HMI-lamps are capable for hot restrike in any cooling stadium 
  

• Photographic industry 
  

• Halogen metal evaporation lamps provide a spectrum composed of a lot of lines, in 
  contrast to temperature radiators, as halogen-incandescent lamps

Oznake sijalica:

Basics:

• GS=Gap Short (shortened electrode space)
  

• DE=Double Ended (double-sided lamp with threaded pin)
  

• SE=Single Ended (one-sided lamp)
  

• PAR=Lamp built in a parabolic reflector 
  

• HMP=Due to their special filling and to their electrode system, HMP-lamps cannot 
  

• only be "dimmed", but also be "boosted", i. e. be operated beyond their rated power. 
  

During this, the light technical characteristics, such as color temperature, color 

rendering index and light output are practically constant during "dimming" and "boosting".
