THE RESEARCH

Q1. What is your profession?

Q2. What is the average power density (W/sq.ft.) used for your open office projects?

Q3. How often are high-performance optical standards required for your office projects - - in other words, using low ceiling brightness ratios (2:1, 4:1, 8:1)?

Q4. What is the most important or prevalent reason(s) that you specify indirect lighting?

Q5. How often do you specify each type of linear indirect fixture compared to the other types in the below list?

Q6. What light source do you most often specify for suspended linear indirect fixtures?

Q7. What type of shielding for the indirect fixture's downlight component do you specify most often?

Q8. What percentage of indirect fixtures do you specify with the following materials?

Q9. When using indirect lighting, what ceiling uniformity are you most likely to use as a goal for the design?

Q10. How often (for what percentage of projects) do you specify indirect lighting into these ceiling heights?

Q11. What are the primary obstacles that inhibit your specification of linear suspended indirect fixtures?

Q12. What fluorescent product do you specify as the main alternative to linear indirect fixtures?

Q13. On a scale of 1 to 5, how influential are the following features with regards to your selection of indirect lighting products?

Q14. How positive is your perception of doing business with manufacturers of indirect fixtures (in terms of product, service, price, value)?

Q15. How should linear indirect manufacturers focus their product development efforts?

Q16: What do you feel the indirect manufacturers are doing well that you would like to see them continue development towards?

Q17: Where do you feel the indirect lighting manufacturers are lacking in their efforts, and what could they do to enhance their product and service more towards your preference?

Why do specifiers choose indirect? What are the barriers to specification? What are specifier preferences in regards to product features? How do they view manufacturers? What kinds of projects are they working on? What are manufacturers doing right and wrong in their view? Based on the results of a survey of 3,845 lighting designers, architects and engineers, the 2004-2005 Indirect Lighting Study offers leading market intelligence, with 104 pages of analysis, graphs and tables profiling specifier use and attitudes toward indirect lighting.

Here's what manufacturers are saying about Indirect Lighting Study:

"I felt that the questions you asked were very pertinent. Being a manufacturer, we constantly get bombarded with product feedback and request for new products. Most if not all of our product ideas come from the lighting community so this feedback is extremely important. Filtering through these requests is always a challenge which is why your survey helps to reinforce many requests we get. For example, we just recently launched the 'twelve' product which is a linear indirect product that mounts 12" from the ceiling. It was very interesting to see that your survey marked low ceiling applications as the #1 barrier to indirect lighting because we have been asked to solve this problem for many years."
