Linear Fluorescent Lamps
Special phosphors with rare earth elements (lanthanides) are used in NASLI fluorescent lamps. Mixture of these compounds emits light across the whole visible range, producing a rich white light that contains all colours. For sake of acceptable decrease in efficacy we get light that enables to distinguish small colour nuances, much like in daylight. This is not possible under mainstream fluorescent lamps.
The lamps conform to all requirements on safety and performance, ERP and RoHS directives and can be used in existing luminaires without any modifications. T8 lamps can be used with electronic or magnetic ballasts. Electronic ballasts are prefered as lamps live longer and consume less energy while flicker is eliminated, which is comfortable for eyes.
