Hi Andrew,

thanks for your help so far.

## ···

...Looking at your IES file, you say you want a distribution with 12 Vertical

Angles of data and 27 Horizontal angles of data. Looking at your angles,

you have indeed provided 12 Vertical angles, but you have only provided 22

Horizontal angles, (unless my eyes are deceiving me). I have checked a few

IES files I have used and converted successfully and these quantities should

match....

----------

Ok you where right on this one, i worked with so many different files, i picked a wrong one.

------

Also I am not sure if you have cut your lumen data up within the e-mail to

save space, but when you write the lumen data should you not have 12 x 27

(or 22) numbers, i.e. 27 (or 22) lines, each with 12 numbers in them.

------

Thats the point i am confused about, i measured 12 vertical angles of this luminaire and 22 horizontal.

When i have a symmetric luminaire, i write:

TILT=NONE

1 5000 1 13[vert.] 1[horiz.] 1 1 -0.2[width] 0[Lenght] 0[height] 1 1 55

0 5 10 15 20 25 30 35 40 45 50 55 90 [vert. degrees]

0 [horiz. degrees]

1623 1582 1618 1693 1815 1979 2169 2185 2166 2111 2273 2511 [vert. values]

0 [hor. values]

What do i have to write when i have the same vertical angles but additionally these

horizontal values and a rectangular shape?

degrees: 0 2.5 5 7.5 10 12.5 15 17.5 20 25 30 35 40 45 50 55 60 65 70 75 80 85 (22)

values: (22) i guess

1623 1628 1634 1641 1658 1677 1705 1744 1786 1885 2064 2254 2546 2905 3247 3864 4579 6024 7642 9496 8984 30789

Best regards,

Christian
