Has anybody spotted a Sainsbury's yet with Solar Powered Belisha Beacons yet? because the Monks Cross store has them - and to be brutally honest, I don't know why they bothered. During the day thay are unlit (charging), and so at night you'd think they'd flash on and off as normal beacons do... but they don't. The "off" time is about 3 times longer than on standard beacons, while the "on" time is only half the time it is on a standard beacon. The LED(s) inside don't come straight on and straight off either, for some reason it was decided that the driver module would dim them in and dim them out (though the dimming isn't very good, and you can see the stages of the dimming). I think there may even only be 1 LED inside each of these beacons, as they are really dim - you can't work out if they are working if there happens to be a Vista Grande in the same sight line as the beacon; and if there is a Vista Grande within 2m of the beacon, then the beacon doesn't work at night!I didn't notice it at the time but the Wallington store has these as well. They weren't actually working though - the recent gloom not helping no doubt. The solar panels look to be far too small to power anything other than a LED and I doubt more than 1 at that. Not enough charge during winter and I bet during the summer, the illumination of the globe won't be bright enough to see against the sun. A case of form over function...
