My wife asked me to change lighbulb and after 2 hours I am here.
HI guys!! I hope you are having a good day!! PLEASE SEND ME YOUR WORK TO BE FEATURED IN THE NEXT CRITIQUE VIDEO :D :D Also, what should be the next topic for next weeks Tuesday talk? Let me know your thoughts xx
when is your next crit video?, i think what would be nice is like form development or plan development, like i find myself with a plan and im like okay.... how do i develop this now?
Surviving Architecture if you could do a video about approach and entrance as I find that the most difficult part for me as silly as that may sound
Art Dray101 YASSS!!!!
Hmm form development or even like little concept diagrams would be effective too
@@misdede1959 yh true actually its something a lot of students struggle with I think
amazing video, i always found it complicated to do this calculation for my designs but i actually fin dit much easier now, thank you !
Honestly I sometimes think RUclips is a better teach than some of our lecturers hehehe
Thank you!! :)
I know... and they call it independent learning.....
Great video! Quality of the video has improved alot!! Well done
Thank you!! :)
These Tuesday Talks are really effective I'm like waiting for them to come out ready to learn heheh, can you like upload on a specific time?
Thank you!! :) Hmmmm what time suits you best?
This is my first video related to this topic and unfortunately i have to say... This video is going totally above the head.
Great explanation! Can you upload the utilization factor table again please? The link in the description is not working anymore.
THANK YOU! keep up the good work 💕✨
You are welcome my friend :). Thank you for watching ❤️
The thumbnail really got me to click I didn't even know it was your video heheh, great content can't wait for next video
heheheheh click bait my friend!! just joking! Thank you!! :)
first of all I would like to thank you for your effort and your excellent video, great job and really appreciate it
Thank you very much!
Thank you for the calculation descriptions.
You're most welcome!
Marvelous. I am going to impress. Ur lecturing so super bcz of ur magical voice. U laugh when u show the room index it's mad me so cute voice and so good explanation. Really got more from you. Can you nothing. Thank you
Thank you so much! I am glad it was helpful
this video is more understandable than other i saw before. but i will watch again.
Good!
Can you please recommend websites that provide all of the lighting info and catalogs ?
So loving your way of explaining things👍👍
Thank you so much! ☺️
I would really appreciate it if you could share the video because RUclips doesn't recommend my videos to others :(
@@SurvivingArchitecture okay 👍
Ok, so this video talks about what I need and provides the answers my lighting-amateur brain seeks. I just have to see this video 19 more times and I’ll be fine. Thnx for the light shedding content. Saw what I did there?? Light shedding… LOL
That's a good joke hahahah. Thank you for watching and commenting :)
Amazing tutorial!
I'm glad you enjoyed it!
great😍😍
Wow, what a great explanation, please can help me upload that utilization table and other tables that you use. Thanks
Helpful video
Thank you for watching and commenting :)
Thank you !!
You're welcome!
thankyou sooo much!
Glad it was helpful!
Thank you for the explanation, it helps me so much to calculate. But I'm still confused where can I find the light loss factor (LLF) for an LED lamp. Is there someone can help me for this?

Great video!! I am learning alot from you!!
i know right shes great!!
Thank you!! :)
heheheheheh you are always commenting nice things. Thank you!! :)
can you reupload the utilisation factor table its not opening.
thank you.
Even showing what you been doing with projects like what's been going on, I'm more interested In you're architectural student life hehe
Very interested I'd like that too tbh
That is interesting!!
Nice lecture
Thanks for liking
Nice , I have room 4mtr* 6mtr * 3mtr high how much lights I need to fix , can you show me an example please , I would be greatfull to have the answer .
This video includes a example you can follow it and use your measurements :)
Thank you so much,but How can I get those tables please?
Your explanatoins are ok but the point is i learned something about it
Thank you for watching!
Hi Rasha, can you please update the google drive link, it's not working anymore. and thanks for the great video!
The link you put about the utilization factor table below isn't accessible 😢
One question: based on your experience, is it common that LLF ignored in most cases because it is close to 1 ?
Proud of you { random arabic guy }
I do not have that much experience on this topic tbh. I have done this calculation for a hanger project only.
hi can i ask for another link of Utilization Factor because when i click the link it said error
Hello, very informative video :). Thnks. Can you share the link for the ultilization table here?
Here is the link: drive.google.com/file/d/1aEYehk-P56409NG944VKM9twsmX9CqJ2/view?fbclid=IwAR3kjtLMzSAXoipUVx3MFjMg2ZZTnS7nvVQclEFQ42FsO5SqXPXgdxN-s1U I hope this helps :)
It does really help thnks 😁
No worries. I'm glad it was helpful :)
@@SurvivingArchitecture its not opening :(
I have a kitchen + dinning area with this dimension (L 15.0 x W 8.0 x H 13.0) in feet ( L 4.5m x W 2.4m x H 3.9m). There are two chandeliers and 6 recessed lights. For the recessed lights, what lumen should I get?
If you follow the video and use the table in the description you should get the right lumen level :)

Hello the link in the Description is not working, can you direct me to where I can find it?
how bot a non square room? an l shape one, how do you measure that area?
can ask for utilisation factor table?
Has anyone managed to find a worth utilisation factor table? None i can find are as elaborate as the one shown. Please help?!?!
It was a good video.
Where can I get that table , it was not clear
Link in description
can you please provide a new link the old one has expired. thanks!
Utilization Factor table link is dead, please update.
Good
Thanks
Such a great video as usual. I like these more theory based videos too. They get into the the technicalities of the industry. What do you think about doing a video based on mathematics used in architecture and how its reflected in the real world (like algebra / calculus). Thanks as always!
Thank you very much! Hmmm do you mean a showcase of projects that used mathematics or the math behind project such as calculating areas, volumes and such?
@@SurvivingArchitecture I was thinking the latter, however now that you've mentioned it, if you could find the details of math used in a project I think that would be awesome too. The truth is I'm terrified by algebra 😅. Are we really gonna need calculus when we're fully fledged architects?
That could be an interesting set of videos, thank you :) lol!! I don't really know the answer to that myself hahahha but I suppose with new software coming out like BIM and computer aided design, calculations would be a lot easier. truth be told we wont really know until we are there haha xD
@@SurvivingArchitecture you sound like a robot tutorial. Lumens are equivalent to 1lumen equals 1 candle,wattage effects Kelvin. THE HOTTEST PART OF A FLAME IS BLUE.
@@SurvivingArchitecture Lighting in space has so many variables, naturally Lighting, color of paint, floor color, etc, no one uses a defined algorithm for Lighting. Too many variables to be an exact science, the only exception is wattage use,amperage draw for circuit, POWER FORMULA.
Hiii... How can find LLF ???
May I have the utilisation factor table again please thank you.
Link is not working.
Any idea where i can find that utilisation factor table you used?
Linked in the description
link is dead
So how do you determine the reflectance number (0.7 and 0.1). How do we get it?. If the room is dak wall, what number will we have? and the LLF number, I really have no Idea which situation we use 0.95 and when we use other number.
the LLF number I think is always 0.95 assuming that you have lazy workers who do not maintain the lights properly haha
what programs do you use?
Do you mean when I am designing?
thank you for this lecture. But, when instead of light type and number, only lux and specific workspace are mentioned then how to find most suitable lamp and numbers?
looking for your reply
I enjoyed the typing sound was very stratifying heheh , good content
heheheh thank you :)
Stratifying? You mean satisfying right? Anyway, good content indeed.
1000 sq.feet library room how much need lum and lights (9w led)
Hello. Can you upload **Utilization Factor** again???
Whatbis the purspose of calculating the room index?
The room index helps in understanding how sound behaves within a given space. It measures the balance between the size and shape of the room and its acoustic characteristics.
There is no value consider of room hight in step 3 calculation while in step 1 there is mentioned so plz guide about where to use hieght value in formula
MAAM MAY I KNOW THE BOOKS YOU USE AS YOUR REFERENCE FOR THE UTILIZATION FACTOR
It was given to me by a lecturer so I don' have a book.
If area of room is circle how we calculate room index?
what if the area is circular? please answerrrrr
Can you review the new markers in The Works
They have new markers? What are they called? I would definitely review them.
CMYK Twin Colour Markers, they have many sets of them
Oh that is interesting. Will have a look. Thank you :)
where can i find the utilization factor table
It's linked in the description box.
@@SurvivingArchitecture ok sir thanks
Hello. Can you upload *Utilization Factor* again???
Is it not working?
Jesus, I'm buying two lamps and see which one I like the most
Simplest method
1600 bulbs how it is possible sister...
Hi
When installing a lamp at a customer , I have to go thru this academic spew ? get outta here . the only constants I have is the area of the room, and a desire from the customer : working light . Maybe 400 lumens on the work surface . You have a task with all the numbers given ( just like academics prefer) Are the lights changable ? are the lights dimmable ? How long is their lifetime ? do you need external driver trafos, 12V, 24V or 230V . How reflective are the walls ? This should be easily calculabel with a rope measure, or a RADIUS extending from the light source . the longer the radius, the more reduced lumen at the end . You dont need a VOLUME with 3 axis, to calculate a room ! With radius, you can simplify 3 axis X-Y-Z into 1 axis R . I had this in school and their working with LUX, lumen per square meter . Its so wrong, because Light is a round shape . Its like putting a square in a round hole ! You can never caluculate it like that :)
Is this correct ? I see a lamp in a catalog, 1000LM on the surface of the lamp.
1000LM / 2meter^2 = 250 (W/m^2) or LUX 2 meters away from the source .
1000LM / 3m^2 = 111 LUX 3 meters away. Find distance from Lumen and desired Lux,
R = SQRT (1000LM / 400 LUX ) = 1.58 meter radial distance from the Light source gives 400 lux on the work surface .
The other way, How many Lumen is required from a lamp 5 meters away from the lightsource, when I want 400 LUX on the wall.
LUMEN = 400 LUX * 5 ^2 meter = 10 000 Lumen !
Instead I may use 2 lamps that is 5000 lumen .
For a reflective value on the wall, multiply with a number over 1.0 matt .
Maybe multiply in bright or dark colors with factor over 1.0 being black .
Nice and easy . Lumen is the light on the surface of the source. Lux is the brightness on the area W/m^2 . R is the radial lenght between the light source and wall surface .
Lux = Lumen / R^2
Lumen = Lux * R^2
R = SQRT Lumen / Lux

Mathematics again, ....🤯
Its really simple and quick though! :)

All of those calculations is so unnecessary. Just say how much lumens is need for a 10m2 room and 20m2 room etc.
You gotta do the math kid
I hate
