I ordered 4 (a backup) to illuminate a room of 10m ² the result is very correct only cool white regret the lighting angle is not as wide as I thought, so I used the technique of mirror that reflects the light;)
When the product quality at first glance looks very good Flirted ca but i have a closer look can see the flaw fixing nothing serious but I have great doubt about the longevity of these spots last for the price: )
