Quote:Recently (last few weeks) they changed them all again (but kept the columns this time) to Metal Halide or something (greenish glow) with 2 long tiger stripes along the road. AND STILL NO SHIELDED LIGHTS. Odd, I would have thought they would have used LEDS!

Quote:To my eyes it's way brighter. But if I use a longer shutter then I can't manually hold it without burring

Quote:I bet that they do use shielded light fixtures. I don’t think that they can just replace the bulbs, and all the new LEDs are shielded. If they’re smart, they’ll also reduce the number if lights, or reduce the brightness to the level needed.You can discuss that with them, but just cutting the amount of light going up will help a lot.
