because I still have to learn ... (note beside consumption, and Kelvin Lumen also reflect the beam angle)

..but I can not chalk up the LED lamp.
After I fell in LED lamps with no name products I have this time set to Philips.
So far, I have been not disappointed.

In the Product Description lot of information is presented in tabular and thus a clear form.
