LED fixtures with a high CRI (90+), a proper lumen package, and color temperature are indistinguishable from incandescent lights.
Unfortunately, most pole lights are 70CRI, too bright, and the light is too white (4000K+).
- Sunspark 1y agoThe wavelengths are spiky compared to incandescent, and the LEDs flicker if they are not DC-driven. The flicker is pretty annoying because the transition is an abrupt on-off. Where I am the city had the bright idea to wrap LED ribbons around the poles in the downtown area to make it look more interesting. They connected the ribbons without diffusers directly to the power source of the streetlight. So what has happened now is that as you drive or walk you are looking directly at an unshielded flickering LED. I still continue to install incandescent bulbs. They look better, and as I live in a cold-weather country the heat they generate is welcomed.
- Zak 1y agoIt's possible to make an LED with a spectrum that is not very spiky, which a fan of incandescent light will likely enjoy. There is a cost to efficiency, which makes LED fixtures and screw-in bulbs with those traits specialty items. A color rendering index and R9 both in the high 90s is usually enough information to pick out such light sources. Flicker is also not a given, but a product of using cheap rather than good methods to power LEDs starting from AC mains power.
