Lamp technology

The F57QBX and F70QBX are compact fluorescent lamps with amalgam technology. The amalgam is a mercury alloy, which is a replacement for the traditional liquid and pellet-dosed mercury. The amalgam is placed in the lamp and provides the following benefits: more stable light output in every burning position, and a wider optimum operating temperature range (since amalgam gives better mercury vapor control).

The unique quadruple tube design results in a shorter overall length, allowing for use in smaller luminaires. Moreover, the horizontal light distribution is more uniform compared to the triple tube lamps.
In certain circumstances (with very low probability), a traditional CFL lamp may smoke and emit a melting plastic-like odour at the end of its life, an incident which is not generally dangerous. It may happen because the lamp voltage is increased, and the ballast still sustains the discharge, thus overheating the lamp. Even though most commercial ballasts are equipped with end-of-life protection, the F57QBX and F70QBX are designed to eliminate the above-mentioned issue by itself.

A small portion of titanium-hydride is placed near the cathode, and in case of critical overheat, the evaporating hydrogen quenches the arc.
