Got one of these from Kirkcowan cycles last week - they posted this out in 24hrs for me too, it's a good buy!!!!
Rode with it tonight and for well under £100 you won't need anything else. Light case is compact and well manufactured, battery is small and light and is housed in a neoprene case that velcro's to the top tube. Light comes with a charger, headlight strap and extension cable if you want to out the battery in a pocket instead of on the bike.
Only niggle is the operating sequence, but I'll get used to that - it starts up on full beam, quick press on the button on back of light puts it to low, another press to flash mode, press again and it goes off - So when going from low to high you need to press it 3 times and have a second with no light.
Brightness? Hell yeah! So bright the moon crapped itself and went into hiding behind a cloud tonight..... Beam spread? Plenty enough for road riding and has a brighter centre point that is wide too. Easily bright enough for off road, lasts 4.5hrs on full beam.Charger has overload protection and an led that tells you when it's charged.
For about a quarter of the price I paid for a Lupine light a few years ago, I now have a much brighter light with a better beam pattern that lasts four times longer. Recommended.
