@CCTVCam @JDreaming You're both right. I have 4 or 5 solar-powered reflectors and 2 very bright AC-powered reflectors. Both kinds are LED.
Living in the subtropics and my roof not getting any shade at any time of the day or year, the solar ones worked great. What I did find is the more powerful solar reflectors, by wattage, weren't as efficient in lumens as the less powerful reflectors o the same type. The 60w (600w incandescent equivalent) solar reflectors were the best mix but I wasn't getting the coverage on the street that I wanted. But as for reliability, they've been tremendous. The first ones have over 2.5 years usage and still show no signs of slowing down. The batteries seems to be holding up. I purchased them in Mexico.
This is almost exactly what I've purchased in the past:
Reflector Lampara Solar Led 50w Para Alumbrado Exterior - $ 498
They come with remotes (although the listed model doesn't for whatever reason) which is nice to be able to adjust the light from a distance but they're virtually universal which means someone else could turn your reflector off. I mounted the panels on the roof and extended the cable to the reflector, if necessary. They use the panel as a sensor to detect the amount of light. When the unit isn't able to charge from the panel, it comes on and turns off again when it's able to charge.
Really, zero issues and up to my property line, they worked great. And for what they cost in Mexico, around $50 USD, they're a steal.
But they didn't have the output that I needed due to lack of street lighting.
So I picked up two of these:
Dusk to dawn sensor so no extra devices required. Comes on well before it's needed and turns off later than needed which is nice. I have a thread showing the video we've been getting off of these lamps. Quite impressive.
I picked up a couple 200W LED lights to properly illuminate the streets, I'm on a corner lot, and they may be overkill. 18,500 lumens of 5000K light. We hooked one up quickly last night to see just how bright they are and it blew us away. This is the Color4K/X. Initially, it's a bit darker...

My only reservation is that no electricity, no light. The lights rarely go off for any length of time in my area but even a momentary outage shows my vulnerability. I may get a car battery, charger and backup board to have a simple UPS. The boards are cheap on Amazon:
Car battery would be the biggest investment but I'd need a small one as longer outages are only due to hurricanes. Last year, we were almost 5 days without power but that only happens every few years.
