Has anyone had any experience of using Dialux software?
It's free, but I was wondering how it compares to relux.

They are comparable - actually Dialux and Relux have the same origin in University research projects.

I have used both - which one you stick with is usually personal choice based on the interfaces and what access you have to manufacturers photometric data.

Like all software, it needs a degree of care and an understanding of the expected result

Thanks Oms.
I know Dialux is completely freeware.
My understanding of Relux, is that you have to purchase the modules. Is that correct?

And, yes. Software should only confirm your initial calcs. But it does produce a nice drawing that you can show to clients :-)

Oh and I've also been told that, if your particular manufacturer's catalogue isn't in relux, you can adapt a standard fitting by changing the lumen output etc.
Can you do this with Dialux?

Relux is free - as are the plug ins from a huge number of manufacturers (which is why it's free)

You can change things like lumen output in both - but other than a very quick approximation for say emergency lighting output for conversion luminaires, you would ideally want to be working from accredited photometrics supplied in TM or illumdat format.

I've not yet failed to get data for a fitting if it's available (I exclude tin basher copies of other fittings that are sold with no testing at all)

I'll have a look at relux as well.
Thanks.
