Economic replacement for HQL

The lamps can be used in luminaires for HQL 125 W, 250 W or 400 W mercury vapor lamps without any modifications to the existing components, provided the control gear is suitable for the higher operating current of the NAV-Plug-in lamps. The maximum permissible choke temperature as defined in VDE and IEC specifications must not be exeeded. If in doubt, consult the manufacturer of the luminaire and/or control gear.
