Preliminary support for Absolute Photometry in EULUMDAT filesSince 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 filesMany 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!
