PROCESSING is clean and looks quite robust. The silver part is likely to be made of aluminum. The base is firmly connected and very stable. The cover of the LEDs is made of glass. Everything feels meticulously crafted and high quality.
PACKAGING: Each spot secured in a protective plastic molding and packed in a cardboard box. The whole then with "bubble wrap" wrapped in CV assigns AMAZON box, which in turn 4 pcs. In a larger AMAZON box (the box would have been enough high women's boots for a pair ...). A little less packaging would have done it! But after all ;-) arrived all 4 spots intact)
Beam pattern: It is clear that for the replacement of a normal halogen lamp only one LED light with many LED's out of the question. This light bulb has a really wide spread range and then the light well distributed (in my application in progress / entrance).
SWITCHING: Very good is the switch-on. Absolutely no time delay and immediately 100% light there! Also no flicker or flicker or other interruptions.
Brightness: Here, however, the brightness of this light source is remarkably. In my estimation, the light is at least as bright as that of 50W GU10 lamps previously used. Visually, it appears almost 10 to 20 percent lighter, but this is probably due to the brighter light color. The light color is warm white - this is a very bright shining, but not cold light. Halogen light acts compared to more "yellowish".
The light also has no blue or green tinge but is really bright and radiant, in my view, best comparable to daylight.
From light forth'm maybe totally convinced, and would not cover the cost of about 9, xx I would like to immediately change the whole house. So we have left the endurance test experience (installation of 4 pcs early September 2013 - when it shows a failure I sign.) 3-year warranty by the manufacturer sounds ever quite well - so one would have to expect at least 15,000 h operating time.
Strong buy recommendation!
