I bought 2 of these lamps series - both warm white / 6W / 480 lm. Hell they are - BUT - they have a different color of light! One is beautiful - pure white light - the other mixes a yellowish-green tint to it (nasty). Since I run the lights, just a 20 cm distance from each other, falling on very.
So it is apparently "hit and miss", a "good" to get copies ... an experience that I'm doing with other manufacturers and types of LED lamps. Since probably only helps "to try and pay dearly."
