Every type of light source renders colors differently. CRI (Color Rendering Index) is a scale from 0 to 100 percent measures how accurate the light source is at showing true colors. Higher CRI value means higher match of sunlight (being CRI 100) and also influence our color perception. Since color perception may probably decides our opinion of goods, whether we buy them or not, many retail environments require the best CRI properties.

Usually if standard items, 3-5 days lead time for sample and we will ship bulk order within 10-15 working days. In case of heavy production burden or customized items, it may take a little longer time.

We offer 2, 3 and 5 year’s limited warranty for different kinds of products or different requirements of lighting projects. During this period, if customers have the proof showing quality issues and that proof is approved by Smile Lighting engineers, we would like to replace the defective ones with new qualified items. Please note that warranty is not equal to lifespan. Our products have more than 50000-hour long lifespan.
