The illuminance is really comparable to a 100 watt bulb and surpasses it felt a little bit.
I can give no information, but I hope it survives the constant switching on and off and the severe temperature fluctuations over the durability.
The light color is slightly towards white, which even in outdoor use is dearer to me. However, they can still be defined as warm white, but because they have a yellowness.
I would highly recommend the Lamp unrestricted
