Delivery arrived very quickly. For now I have only exchanged one of the 3 LED spots in the bathroom and surprisingly really is the Mailux at any point behind the Halo Spots. Light is bright, pleasant and the viewing angle is softer and larger than in the original spots (what was desired but also in my area so).
A deduction of points I have to give, unfortunately, since they are not mechanically 100 percent compatible with the original Halo Spots. The headband of Halo versions can no longer be properly used (by force) :(
Whether they are really good to be seen, because the durability I can not say anything yet after 1 day;)
