Blended light lamps

D (Д) - дуговая
R (Р) - ртутная
V (В) - вольфрамовая

Light generation of in these lamps is simultaneously carried out by mercury arc discharge of high-pressure quartz burner and serially connected tungsten incandescent filament . Blending of light fluxes of these sources allows to improve color rendition of mercury discharge emission in red spectrum range.

The filament at the same time serves as an active arc discharge ballast and enables lamps work directly from AC supply of 22 V and 50 (60) Hz.

DRV lamps can be used as a direct substitution of incandescent lamps in fitters with corresponding cap since they need neither ballasts nor starting devices.

Universal burning position.

Application :
- street lighting;
- lighting of parking lots, car parks, railway platforms, quays, cattle farms and threshing floors;
