 Comparison of Switchstart Chokes and High Frequency Ballasts
Home
FeatureChokeHF Ballast
CostLowHigh, often 10 times the cost of a choke
Size and weight Generally small and heavier

Generally larger and lighter
RobustnessMore robust to extreme supplies and environmental situations. A choke is less efficient and generates more heat, but can operate at higher temperatures.More vulnerable to extreme situations. The HF Ballasts
Power Factor CorrectionTo reduce the power consumption, it is necessary to add capacitor to the circuit which adds cost.Power Factor correction is normally built into the HF Ballast
Power Consumption

Circuit watts is typically higher due to losses in the Choke and 50Hz operation, For example circuit watts for a 28w 2D Lamp is 36 Watts

Circuit watts are typically much closer to lamp wattage because of lower internal losses and high frequency operation, circuit watts for a 28w 2D lamp is only 29 watts
StarterA Starter is required which has to be Replaced periodically No replaceable starter is require in a HF circuit
Lamp Flicker operationOperating at 50Hz lamp flicker can be perceptibleNo lamp flicker is perceptible at 30 kHz
NoiseAudible noise can occur Little or no audible noise
Light output Light output will change as supply voltage varies and a choke is not as efficient as a HF Ballast
The efficiency is typically 10% higher,therefore light output is higher and also more constant due to precise control, even
if supply varies
Lamp LifeLamp Life is generally achieved
Lamp life is often exceeded by 50% due in the main to soft starting and more precise
control
Running costsHigher due to higher power consumption and the more
frequent lamp replacement
Lower due to lower power consumption and longer lamp life
Operation at Low TemperaturesOften problematic to start and run lamp below 0°C
Will typically operate lamps down to -15°C
Operation at end of Lamp lifeLamp will continue to flicker until replaced and the circuit may be damaged.
A defective lamp will be switched off automatically
