Korea, in our country almost use from 20W to 30W for the celling light.

but i confused about emitter. i have readed post about intensity of emitter in forum. sometimes i saw that they used almost more than 150W.

it seems that different between unit scale. i use unit to mm scale

ok. thiis is question what i have.

so, have to i use intensity to 20W that is used in our country? or 200?

because of 200mm equal to 20cm.

let me know what you think and please leave standard intensity of light in each location you live

thaknks!

It also depends a bit of what type of bulb you use, nowadays alot of places and homes use the lowenergy bulbs at 15 watts and around that. They emit as much light as a 40 and 60 watt bulb does. Atleast i only use 15 watt lowenergy bulbs in my home. They last longer, cost more and emit just as much light

But normally 40 and 60W bulbs are most common here if you don't go into some big store or similar structure..

Well, I guess this depends on the habits and room sizes.

Here in Germany the total W per room is somewhere between 60W to up to ~150W for a 15-20 m^2 room.

thanks for the quickly answer Maximus3d and kabe!

so, as you say,do you adjust 15W in intensity of Maxwell emiiter?

mm,it seem that lowenergy. i don't think this energy enought to fill brightness in space.

btw, what do you think about that using 150W? i saw that value a few day ago in this forum.

maybe this link. http://www.maxwellrender.com/forum/viewtopic.php?t=4097

i mistake leaving a word

what i saying about intensity used in shop like shop of clothes and etc..

But i don't know.. in all the Maxwell tests i done here it seems that Maxwell's lightintensity isn't yet connected to the real world lightbulb intesity. If you wanna use real values now then you will probably not get good results, too dark and moody scenes. Atleast that's what my tests shown as i always have to boost the intensity of my lights into infinity :/ but i'm sure they fix that in the future with IES or what it's called heh

If you're into realworld lightsetups then i can only suggest trial'n'error now until you find what looks good.

But as usual i could be wrong hehe it's nothing unusual

this is cause of confused i have.

i have known Maxwell's lightintensity connected to the real world.

ahha!, mm yes you're right

i really hope this be fixed in the near future too

well, the real problem is that maxwells does not support IES data, so there are no phisically correct lights right now, another problem i see is that lights are measured in watts, but if you check with different manufacturers there are several types of lamps depending on the method used to generate the flux, is not the same using an incandecent light bulb than a mercury or halogen light. I think lights should be measured in luxes or candelas o lumnes, just as in real life. Check manufacturers, they measure the intensity in those units, watts are only for power consuming purposes. Hope maxwell soon incorporates IES data and a way to measure intensuty in lumens or luxes, just the way IES lights works in max.

Just my opinion.

[Mihai]

IES is an approximation, and a pretty crude one I think. It's true Maxwell needs to have other settings for lights other than watts, but having IES does not mean you have physically correct lights.

If you model the fixture instead, you will get more physically correct light intensities than with IES.

i have been used 20W lightbulb, but result was to be very darkness.

as says above, it seems that lightsetting in maxwell isn't yet connected to the real world

thanks

[cyberjuls]

But who is going to model all fixtures mihai ?

[Jun In Gi]

well, the point of this thread , what i says, was brightness with light bulb value. and i have confused cause of mention like above post.

but i think this problem isn't to be big issue, if i'm not mistake, more important thing seems that is camera setting like fstop and SS between space and time, day and night in archtectrue scene.
