DIALUX LIGHTINF DESIGN EXPERIENCE **Rating:** 4.5/5.0 stars **Reviewed by:** Muhammad Waseem A. | Deputy Manager Electrical, Small-Business (50 or fewer emp.) **Reviewed Date:** April 29, 2021 **What do you like best about DIALux?** VERY HELPFU IN MAKING LIGHTING DESIGN FOR ANY TIME OF BUILDING AND ALSO THE DESING IS IMPLEMENTED USING REALTIME SINERIO AND ITS EASY TO SEE WHAT WILL BE THE PROBLENMS BEFORE ORDERING MATERIAL REAL TIME AT SITE. IT GIVE A BROAD VIEW OF THE MY WORK BEFORE PRESENTING IT TO THE CLIENT AND GIVE ME CONFODENCE ON WHAT I AM RECOMMENDING TO THE CLIENT. **What do you dislike about DIALux?** THE THING WHICH I DISLIKE THE MOST ABOUT THE DILUX IS IT LIGHTING SELECTION FROM DIFFERENT MANUFACTURE AND IS ONLY GOOD AND FIT FOR THE DEVELOP COUNTRIES BUT IN SOUTHASIAN COUNTRIES WHERE THEIR IS PROBLEM OF DIFFERENT MANUFACTURER LIMITED LIGHT FIXTURE AVAILABILITY IS THAT IF WE CONDISERED SOME LIGHT FROM DIALUX LIGHT FIXTURE CATALOG I MAY OR MAY NOT BE AVAILABLE .SO BEFORE MAKING ANY DESIGN I HAVE TO CONSIDERED THAT LIGHT THAT I AM PROPOSING FOR SOME CLIENT IS EASILY AVAILABLE IN THE MARKET.OFFCOURSE DIALUX HAS NOT TO DOMUCH WITH THIS PROBLEM BUT THEY CAN HELP IN THIS REGARDS. SO BASICALLY ITS A OBSERVATION FOR THE IMPROVEMENT OF THE SOFTWARE USEFULL NESS AND INDUSTRY PROBLEM THAT ANY LIGHTING DESIGNING FACE IN UNDER DEVELOP COUNTRY. **Recommendations to others considering DIALux:** use dialux for lighting designing but before that if you are working on already build architecture drawing first you have to rebuilt the same wall and floor layout and then add light fixture as per your requirement.it can also import file from autocad in 2d for clear understanding of the required area for analysis and desining. Dialux is free software so thank to dialus for providing support to the concerned industry professionals. **What problems is DIALux solving and how is that benefiting you?** MAKING DESIGN OF THE LIGHTING REQUREMENT ACOORDING THE HOSPITAL STANDARD BY USING DIALUS IT HELP IN SELECTION AND IMPLEMENTION OF HOSPITAL LUX LEVEL STANDARDS AND IT GIVE ME BROAD VIEW INTERM OF IMPLIMENTATION. ALSO DIALUX HELP ME TO PRESENT ALL LUX LEVEL CALCULATION IN MOST PRESENTABLE WAY TO MY OTHER TEAM MEMBERS TO HAVE QUICK DECISION WITHOUT WASTING TIME AND ALSO HELP IN OVERCOMMING UNKNOW COST. ### 12.
