Processing: pretty neat, all openings sealed with a soft plastic seals.
Power supply: housing can be combined with "normal" tool (Phillips) open, inside a terminal block, cable entry large enough.
Wall mounting: headband is so far insufficient, the lamp almost 180 degrees can be rotated.
Light: really surprisingly bright, the comparison with "100 watt halogen" the previous speaker fits!
Weather resistance: the first (violent) rain days has the part apparently unscathed, the plate is dry from the inside still.
Conclusion: for smaller areas (with us is about 2.5 x 3.5 meters) Highly Recommended!
