The price was the decisive factor. I know some very good 3.5 Watt SMD LEDs, I had faith in the values. The design did not matter, because under grooved glass barely visible. However, the light color of my feeling here is bad - as LEDs first type, has nothing to do with a warm white incandescent lamp or good SMD LEDs. And the 180 lumen reaches the lamp hardly. They say: lumens divided by 10 = Watts of a conventional lamp. Since I in my lamp 3 x 180 lm, ie 54 Watt had built, I am not satisfied. Choose ye better LEDs because of 3.5 Watt SMD LEDs to win today much better light with more luminosity.
