IES File of a light bulb?

[B.Y.O.B.]

Hi,

I'm searching for an IES file of a common household lightbulb (naked, without any lampshade).
Does someone have a hint or a link for me where to search?

regards
Simon

Hi,

You should be able to find such files on light bulb manufacturers web sites.

There are a few nude bulb ies files here, unfortunately they only seem to have files for the reflector globes.

Thanks for your replies.
These manufacturers websites are written somehow complicated (at least in a language I don't completely understand) so it's rather hard for me to find IES files on such sites.

I found for example this page: http://genet.gelighting.com/LightProduc ... dCode=null
This would be a bulb of the shape I need, but I don't find an IES file download button or section

If I just type "ies" in the search field, I get many download links, but no description of the bulbs these files belong to

It would be very kind if you could help me out a bit, I'm somehow lost

This looks like a possible as it gives you the catalogue numbers of the bulbs as well. Since I don't actually know what an IES file is, I can't be much more help...

Unfortunately the Ge lighting only appears to have files for the reflector globes, essentially a lampshade within the globe.
Like this one http://genet.gelighting.com/LightProduc ... CODE=20332 :

I believe generally .ies files are specific to the fixture used as opposed to the bulb itself.
If you have a fitting for a globe on a cable perhaps you could photo it close to a wall and create your own. Or render it with luxrender if you can find a model of a globe with accurate filament (maybe one on this forum).

Thank you for your help

By the way, is it better to use a meshlight, a pointlight or a spotlight for such a case?

On page 4 of the E27 lamps, this page has some bare incandescent bulbs in Eulumdat format:

There is a free converter to IES called eulumcnv.exe floating around the internet:

Bit of ot, but do you know software that could batch render .ies files? Or does iesviewer has some commandline options for that?
