In the design stage were fluroscents light have a 1.8 correction factor do sons have a similar correction factor

beat tel this time , he-he.

Ok biff is it the same 1.8 value and can you get high frequency sons as the correction factor doesn't need to be applied for high frequency fluroscents

 

[Guest55]

not heard of HF sons , just for florries as far as i know.

 

[Farmelectrics]

Ok thanks for advice

 

[Guest55]

the 1.8 factor is just a rule of thumb , if you have the manufacturers data and the figure is lower , use that instead.

 

[Farmelectrics]

Ok cheers

 

[Guest55]

is this a real job or college homework ? :-D

 

[telectrix]

yes , as do all discharge lighting types.

As Biff quite correctly states, the 1.8 factor is only used when your not in possession of manufacturers data.... In most cases the real factor will be much better.

Anyone remember those old 8' flu fittings that could draw almost 2A a piece?? ..lol!!

its ok really with an experienced tutor , the project was by far the most enjoyable part for me.
just wait till the 3 hr written exam though , its a train wreck lol ! nothing like what i expected.

If its the 2391-20 course you are doing (or whatever the new numbering is for it) then the 1.8 factor should be suffice, its just an exam!!. Questions dont tend to give you any manuf data but if they did then use that instead.

And the 3 hr exam will soon fly past, just make sure you've had a go at all the questions ......
