Frequently Asked Questions About LED Lighting Parameters
What is the best CRI for warehouse lighting?
CRI 80 is generally sufficient for warehouse aisles; use CRI 90+ where color-coded labels or safety colors must be distinguished.
What IP rating do I need for outdoor LED lighting?
IP65 minimum for outdoor walls and bollards; IP66 for coastal or heavy rain areas; IP67/IP68 for immersion.
What is a good efficacy for commercial LED lighting?
100-130 lm/W is good; 130-160 lm/W is premium and usually DLC Premium eligible; 160+ lm/W targets utility rebates.
How do I choose between 4000K and 5000K?
4000K is neutral and comfortable for offices; 5000K is cooler and better for factories, inspection and hospitals.
