An HF-ballast increases the fluorescent lamp’s working frequency to approximately 40 kHz, and in doing so lights the fluorescent lamp completely evenly without flashing. At the same time efficiency is improved by approximately ...
Fuse protection of HF-ballasts
The inrush current is caused by the capacitors in the HF-ballast’s mains filter. The size of the inrush current is not dependent on the output of the HF-ballast’s but its design. The inrush current varies from one HF-ballast manufacturer to another. Du...
Ecodesign requirements fluorescent lamps
Ecodesign requirements for fluorescent lamps without integrated ballast, for high intensity discharge lamps, and for ballasts and luminaires able to operate such lamps.
Product information requirements on luminaires for fluorescent lamps with a...
Research studies have indicated that people in workplaces where luminaires equipped with HF-ballasts are used feel better, are less tired and achieve more. Not everyone is aware of the flicker from fluorescent lamp luminaires equipped with ordinary ballas...
HF-ballast – Fagerhult’s policy
When designing luminaires we make sure that the temperature of the HF ballast does not become too high, as this can shorten the life span. When a luminaire is installed and used correctly the life span for the HF-ballast is at least 50.000 hours with a ma...
Correctly optimised ignition of fluorescent lamps, where the cathodes at the ends of the lamp are pre-heated to the right temperature, allowing controlled discharging to take place. This creates the best conditions for maximi...

This chapter is filled with information about lighting standards, instructions and tips for your light planning.
Fagerhult are developing luminaires specifically for LEDs, creating viable solutions across the whole spectrum of a lighting project.
Here we have gathered tips and solutions on how you can work with lighting in different types of public areas.
Light, or light radiation, not only affects our visual cortex but also the whole of our alertness, wellbeing and performance.
