The problem here is not they cylindrical or black, that's all well and good.
The problems are the way in which they direct light (it should always be pointed down, unless you're intentionally uplighting something); there are too many of them, too close together, and they are too tall.
You don't want to light up the sky, that's wasted energy, and bad for wildlife and has no safety value. You want the light, generally, within about 8ft of grade (when over a sidewalk or path), for roads, you typically want higher to allow for truck clearance.
