New version 0.6.6.v20100416 released

Today I released a new version of Eulumdat Tools. It is available as Eclipse plugin or standalone RCP application for Windows XP, Windows Vista/7.0, Mac OSX 10.5 and Mac OSX 10.6 64 bit.

Preliminary support for Absolute Photometry in EULUMDAT files

Since August 2009 the EULUMDAT standard was modified to allow Absolute Photometry as described here. The new rules boil down to the following changes:
  • Only one lampset is allowed
  • LORL is set to 100%
  • The number of lamps (line 26a) is set to a negative number

IES files with Absolute Photometry translate to the new format EULUMDAT files

Many LED light sources have photometric data provided as IES files. Eulumdat Tools allows easy conversion fo such files for use with softare such as Relux or Dialux.
EulumdatTools will also help manufacturers and importers of new energy saving light sources such as LED's to provide accurate and consistent photometric data.

Numerous smaller bugs in correctly displaying grahics for these lamps were also fixed


Thanks to Fanis Kavouropoulos and Linuz Backelin for helping track down and reporting these problems!

New version 0.6.3.v20100410 released

Today I released a new version of Eulumdat Tools. It is available as Eclipse plugin or standalone RCP application for Windows XP, Windows Vista/7.0, Mac OSX 10.5 and Mac OSX 10.6 64 bit.

Improved IES file header parsing

IES files can contain many custom parameters, but these were not parsed but seen as errors.
Examples of problem lines:
IESNA:LM-63-1995
[TEST]
[DATE] 02-01
[MANUFAC] GE LIGHTING
[LAMPCAT] 30754
[LAMP] Q20MR11/SP15-FTC
[_CATEGORY] HALOGEN
[_SUBCATEGORY] MR11
[_BULB] MR11
[_RATED-CBCP] 1760
[_CANDELA-MULTIPLIER] 1
[_RATED-LUMENS]
[_RATED-LIFE] 3500
[_BEAM-ANGLE] 15
[_DETAILS]
TILT=NONE
...
LInes starting with [_ will be ignored from now on, resulting in less editing being required in existing IES files.

Fixed div by zero error in rotation symmetric IES file parsing

Rotation symmetric IES files did not convert to EULUMDAT properly but resulted in an uncaught exception.
A proper error dialog was added and the cause of the div by zero fixed.
Also the offending files were added to the regression test suite.

Thank you Linuz Backelin for helping me track down and solve these two problems!

New version 0.6.3.v20100408 released

Today I released a new version of Eulumdat Tools. It is available as Eclipse plugin or standalone RCP application for Windows XP, Windows Vista/7.0, Mac OSX 10.5 and Mac OSX 10.6 64 bit.

As I'm still in BETA stage I hardcoded an expiry date into the program, but forgot to update it. Very bad!
I'm also starting to handle PayPal payments, though the interface does not work very good yet.
Also EU VAT rules have changed so this requires a major effort to set up in terms of financial administration.

Many apologies again to my first customers. Please bear with me.

Please vote when you think IES to Eulumdat file conversion is a major item for Eulumdat Tools.
