First of all positive. This light is very bright; Works great even in bright daylight. Now for the downside. This light is only visible when you are on the same plane as the light. This lamp is equipped with LEDs mounted in the top plate and pointing downwards. The light emitted by the LED is then reflected in all directions by a very nice polygonal mirror, but in the same plane as the light. In other words, if you park at the bottom of a hill, someone walking over the crest of the hill will not see the light until their eyes are at or very close to the level of the light. Luminaires with the LEDs facing outward lose some of their brightness if you view them from an angle above or below the direction they are facing, but you still see the full light. If you look at this light more than 10 degrees above or below the light level, you will see almost no flare. If you're using this in a situation where you're always on the same plane as the person you're trying to see (airport, most parking lots, in a warehouse, garage, etc.) this is great. However, if you use it at a construction site where your car may be parked at an angle, such as B. on a construction site, you will not be satisfied.
