**LONG TERM REVIEW** I keep chickens at the bottom of my garden and last year we desperately needed a source of bright light around the coop to impact on a fox problem in the area, which had killed 4 of our chickens. With no mains power there, the only solution was solar powered security lights. Having spent a number of nights looking on eBay and local shops I came across the Evo 56 units by The Solar Centre. The price for 2 units was within the budget I'd put aside for the job, but at the time was sceptical that solar LED floodlight would give out enough light, but took the plunge.
On opening the package, I was impressed with the build quality and how easy they were to fit. The solar panels mount is really handy because it has 2 hinges on the mounting plate allowing you to mount the panels on the apex of the coop roof, or I could have flattened the hinge and mounted it flush to the south facing coop wall. I gave the lights a couple of days to charge the batteries before turning them on. That evening, once dark, we tested them out, WOW!! They were bright and lit the area of the coop and run perfectly. Whether it's the lights or not, but we haven't lost a single chicken since the installation!
Last winter was harsh, and I found that as long as you turned the lights duration down slightly, the solar panels had no problem at all with charge. No time during the winter have we had to turn the lights off for the batteries to charge, which to me speaks volumes about the quality of batteries and panels used in the units.
We've had 500W halogen lights on the house in the past that after a few months all the paint would peel off the metal surrounding the glass. The lights I have here, other than dirty from rain and snow, are still as they came out of the box.
If you need a good source of bright light, but have no way of running mains power to that area, I can recommend these lights with 2 thumbs up!!
