What are the guidelines for the use of ballast
You can't use it, first the light source and the ballast power match. 28W ballast with 14W fluorescent lamp, current too big, the light source is easily damaged.
No ordinary inductance ballast should be used The national standard gb50034-2004 stipulates that "direct tube fluorescent lamp should be equipped with electronic ballast or energy-saving inductance ballast." These two kinds of ballast are better than ordinary inductive ballast. The European Union has also banned the equivalent of the c-grade product, and the national standard of our country has made it clear that it should not be chosen. The application of electronic ballast Electronic ballast is an obvious advantage in improving the energy efficiency and quality of lighting system, which is the product of the new international recommendation and the trend of future development. Selects the suggestion: (1) in the continuous tense visual workplaces and high visual requirements (e.g., design, drawing, typing, etc.), on request special quiet place (room, office, etc.) and teenagers to view places (classroom, reading room, etc.) should be preferred. (2) in places where light is needed, a three-base fluorescent lamp can be used with a tunable digital ballast, replacing incandescent or halogen lamps, which can greatly improve energy efficiency. (3) should choose product of high quality, low harmonic, should not simply pursue cheap, should satisfy the requirements of the use, consider running maintenance effect, and comprehensive comparison.
The power of a ballast is equal to or greater than the power of a lamp. The inductance ballast can start performance poor and overload capacity. The electronic ballast is less power-hungry when it starts performance.
Select ballast need according to lamp power size to choose, is 40 w tubes can only choose 40 w ballast, electronic ballast, and preferred brand bigger, quality assured. In fact the lamp tube has been phased out gradually, still choose LED lamp is better.
First of all, do you choose an electronic ballast or a inductive ballast? Of the electron is needless to say, the inductance of the main is 1 of 2 to make their own power loss is small 3 what material is the temperature rise is low with 4, has a copper wire with aluminium wire 5 how much is the power factor and so on
