Yes it’s a 900. I have 3 or 4 of the 400’s - but have the 900 for when it’s needed.
*900 is also Aluminium bodied (400 series being plastic) and the 900 has many more settings / flash rates / intensities etc
So….er….yea: it’s great ! So good I only use it on low setting. More than bright enough - and my eyesight is not wonderful. So on low it lasts hours and hours.
More than enough I think 🤷♂️

I've had an AMPP400 for years as it seemed the best compromise between light output, battery life and cost. I have found it pretty good. I'd never run it to the end of its battery life until recently and was assuming that it would go into flash mode for some time before expiring. Towards the end of my last long ride, around 2 am on a particularly dark night I noticed that the switch had turned red so expected it to start flashing soon, hopefully for long enough to last me the remaining 20 minutes through the lanes to home. Nope. It went from a decent bright light (even on the low setting) to pitch black. Fortunately I was just rolling along on the flat at the time. A few minutes previously I'd been grinding up a series of uphills and zooming downhill into a series of dips. That might have had some exciting consequences, to say the least, if it had happened then.
I stopped and fitted a rather dim backup light to get me home. I've since wondered about getting another AMPP400 to use as a backup light, or one of the higher specced ones, and use the one I've got as backup. I've got a cateye mount on my other bikes, even the ones with dynamo lights, as belt and braces.
I've often wondered if anyone actually uses the high power settings much on the higher powered ones if they are going far, for fear of having a shorter battery life. There's the faff of fiddling with switches once you've got going, versus the fact that if you've got the power, it's addictive and you're more likely to use it. Even so, I've had oncoming cars flash their lights at me even on the low power setting until I've got it pointing just in front of the front wheel. Even if you've got a light that's so powerful it can melt tarmac, it's not so useful unless you can point it further ahead.
Much better when there's nobody about, of course. It's a conundrum.
