I have two questions for u sir 1)u assumed value directly for wall colour type& fixture mount type was 70% to 0.7 whereas why did u subract 5 %from 100 %for maintenance factor before converting into the value of 0.952)why did u divide by 3 for c.u.f after adding the those 3 factors(wall color type +fixture mount type + room index)
Sir, may I ask you a question how to mature the external quantum efficiency if A particular deep blue commercial LED emits an optical power of453mW at 455 nm when the current is 350 mA and the forward voltage is 3.2 V? Thank you.
nice video...I didn't find the other areas lux level info. in the description box as you mentioned. Can you please update that! OR any website we can find the recommended Lux?
HI SIR, FOR NORMAL A ROOM HEIGHT( 3.0M), THIS LUX AND NO.OF LIGHTS CALCULATION IS SIMPLE METHOD .DOES THIS SAME LUX AND NO.OF LIGHTS CALCULATION FIT TO DOUBLE HEIGHT(6.0M) OF A HALL?COULD YOU CLARIFY THE DOUBT/ PROBLEM .
This is the 2nd time I watched the video it is really helpful continue forward , Could you pls show the table value of lumen fir each place ,such as bedrooms,hall,kitchen and so on ,another question , is the UF and MF values are constant at each place or not
Sir, Suppose total required lumens is 5000. If 15w LED gives 1200 lumens and 18w LED gives 1440 lumes.which LED will you select & Why? Please give me reason sir
Select any one. Only the quantity of fixtures shall be increased. Total value may be more than 5000 and aesthetic look of array of fixtures to be taken care.

Thanks Sir... Its really very Elegant Video and yours presentation as well...
Sir ,are these calculation & standards apply equally for British & American standard?? Same for gulf & indian construction projects
How will you select the head for outdoor, especially for highmast or street lights
This was so helpful. Thank you.
Welcome 🙂

Very good lecture. A very good teacher.. respect from me.
Thank you
very nice Explanation sir thank you so much sir
You're welcome 😊
Well explained
Good video, explained each and every detail required for calculation of lumen and no. Of fixtures
Thanks
We buying a led 23 Watt E27 2100 Lm for oil and gas Area it's a good dial?
Sir, may I ask you a question how to mature the external quantum efficiency if A particular deep blue commercial LED emits an optical power of453mW at 455 nm when the current is 350 mA and the forward voltage is 3.2 V?
Thank you.
Thanks Sir
Very nice
Very nice sir...but what is type of fixture pls explain u say take one but how sir
Hi, I like your lecture. Thanks
Thanks
your way of explanation is very good. Its worth watching. Thanks a lot for sharing; god bless you
Thanks so much
Bro u r channel is awesome.... Today only i visit u r channel. ... I watched more then 5 videos.... Keep rocking bro
Thanks so much. Share with your friends who study electrical. Help them too.
great video
Thanks 😊
nice video...I didn't find the other areas lux level info. in the description box as you mentioned. Can you please update that! OR any website we can find the recommended Lux?
Will notify you once I update it.
Sir in type of fixture number of lights in a units means ?
Nice and excellent explanation. When are you going to upload lux levels of different places, please?
If the light is hanging form celling them what whould the HM???Should i consider the hight from floor to bottom of lighy ??or form floor to cilling???
suspension height of light fitting.
Sir there is no lux levels mentioned in description as you said in the video
Very nice explaination for calculation for lamp calculation
But fixing of lamp should be in x-2x-x that's become more better.
Great explain sir.Thanku you
Welcome
Thank youuuuuuuu very much
Welcome 🙂
HI SIR, FOR NORMAL A ROOM HEIGHT( 3.0M), THIS LUX AND NO.OF LIGHTS CALCULATION IS SIMPLE METHOD .DOES THIS SAME LUX AND NO.OF LIGHTS CALCULATION FIT TO DOUBLE HEIGHT(6.0M) OF A HALL?COULD YOU CLARIFY THE DOUBT/ PROBLEM .
It will do yes, just factor in for the room height and you're good to go! Hope this helps
good explanation mate! much appreciated
Thank u so much 😊
@@ElectricalInfinity bro just one question, what if there are two types of light in a room . eg: 9 lights and a chandelier???
Very useful
Thanks 🧡
This is the 2nd time I watched the video it is really helpful continue forward ,
Could you pls show the table value of lumen fir each place ,such as bedrooms,hall,kitchen and so on ,another question , is the UF and MF values are constant at each place or not
Thanks for appreciation ❤. Will alert you once I update it.
Can you please tell about how to measure the height at which a screen is to be placed for 70 lux and 800 lux
You can use dialux software for checking lux level.
well explained dude... worth for watching...
Thanks
Very well explained
Thanks
@@ElectricalInfinity suppose we have lumens and wattage and area. How to calculate lux
Sir, Suppose total required lumens is 5000. If 15w LED gives 1200 lumens and 18w LED gives 1440 lumes.which LED will you select & Why? Please give me reason sir
Select any one. Only the quantity of fixtures shall be increased. Total value may be more than 5000 and aesthetic look of array of fixtures to be taken care.
Thank you Bhai!
where did you mention the lux values of different areas in the description it is not available here
I have a project, how do i know the lux leval for a funeral home
Sir i want to find out the lux ...my lumens value is 6000....what is the lux
why you take 1 for Type of fixtures ?
lux level is not mentioned in description of other areas
🤓super
Thanks
Pls explain power factor bro
Why you divide cuf on 3 plz guide
Illumination engineering Ka aur numericals solve kariye na
why type of light fixture 1?
Good explained
Room index value ?
Utilisation factor formula is incorrect. At some length , it even crosses 3 whereas max value is 0.7.
Description main nhi hai bhai lux
Will update soon
Sir
Check for centimetre
Type of fixture is not clear.
Here I m little confused.......
what is lux how calculate lumens from lux

You are trying to understand this by reading it yourself
If it's for viewer, so it not write too small
Sorry for that, please watch new videos you can understand easily from them.
