The only thing I think these are ok for is where it's difficult to get power to such as above a bridge on a sign. For anything else such as replacing a mains one, I don't think it's worth it at all. They are ugly, oversized, overpriced and I can't imagine the batteries lasting more than 5 years. The mains version of these lights are ok but, I have seen them and they seem to suffer from faking paint after a few years! I think the Reddilight brand name came from the location Redditch. A good old 2 x 8w sign light would be much more reliable and brighter by miles. I can't see these working after over 20 years!

I doubt these could be better than a mains installation. I can't imagine the energy saving being more than the power consumption of a mains one. Plus, the mains one will need less maintenance as there would be no battery or solar panel to clean. Some of the sign lights here are under trees and gone green. A solar panel wouldn't be very good covered in algae!

Yeah but how much???? How much does an LUA cost? I bet not 700+ quid lol

Yeah, LUAs are no where near that. LUAs are better than these anyway. They can be easily retro-fitted and LUAs actually use really good paint! There is also a photocell window so no chance of water getting in the photocell.

What's the point in having an on-off switch on it anyway?

The construction is weird, but it doesnt look anything "smart cloud based style" so to speak, which is a positive thing in my book

We had similar lights installed in Israel in the 80s/90s but with rectangular panel/battery box, and the lantern was a standard lantern on an arm below it. And they worked well, i suppose with the occasional battery replacements. Though on a "wet" battery it might have done 10 years straight without any maintenance too

I looked closer at the image and I see the switch. I can't imagine why there would be a switch and I wonder what it actually controls. I notice this one is also suffering from bubbling paint!

Can forgive it for a bit of flaking paint I suupose since it's about 20m from Collingwood dock and about 100m from the River Mersey...

I've seen the ones in Gateshead with loads of the paint missing.
