The HFP-800 High Frequency Power Supply works with LPS-3 (Lamp Preheat Assistant Source) and RB-3 (Adjustable Resistance Ballast) to be an IEC Standard Test System which used to test the high frequency fluorescent Lamp such as T5 Tube. Please visit this page to view How to Measure the High Frequency Fluorescent Lamp. It is fully meet the ANSI-ANSLG-C78.81, ANSI-ANSLG-C82.11, IEC62776 , GB/T-...
High frequency fluorescent lamp came out in 1990. Fine tube, small current and high power is the distinct features. Because of the above design structure, high frequency current working, electronic ballast with low power consumption, the work system of this high frequency fluorescent lamp is superior to the traditional lamp on the aspect of lighting effect and photometric. How to measure the chara...
Comparing with traditional fluorescent lamp, the LED tube have high light effects, low power consume, long life time and stable luminous efficiency advantages etc. At the same time, for the LED tube performance testing is became more simple, in recent years more and more customers has chosen the LED tube to replace fluorescent lamp. Due to the main lighting products are consist of traditional fluo...
The ballast (resistor ballast) is a device for limiting the flow of sunlight and generating instantaneous high pressure. Following is some difference between the electronic ballast and inductance ballast. 1. Inductance Ballast is an iron core inductance coil, the inductance characteristic is when the current changes in the coil, the magnetic flux changes, resulting in the induction electromotive, ...
