AMPP1100

Pros- Really easy to install, and the fixture holds nice and tight without slipping. The light has a small amount of play to allow you to angle it away from oncoming cars which is a bonus. Multiple levels of intensity gives great versatility - at 400 lumens I can still see enough even on completely unlit stretches. 1100 lumens is great when I get off the road and could do with being able to see more of my surroundings. Two different flashing patterns are great for added visibility during the day. Seems to be really well-built, and has a "premium" feel. Has survived a couple of moderate showers, though it hasn't yet been tested in prolonged heavy rain. Cons- Bit on the pricey side, though as I said it does feel like a premium product, and I don't feel ripped off after spending £60-ish on the set. Battery life feels a little stingy. I'm lucky that I only have to use it for 30 mins at a time in the early hours so I only need to give it a top-up every other day. Worst case for me is that after about three days of this sort of use it went into the red. I could see it being a pain if you needed to charge from empty every day though. No way to change intensity down, you have to cycle through brightness levels in order. This is only a minor thing but if I want to step down a level (say from 1100 to 800) I have to make four clicks, which means scrolling through the two low-power flashing settings, and that's not ideal on the move in the dark. All in all though, I highly recommend this light. I'll definitely look to Cateye when I get round to buying a backup light, and I would definitely buy another one of these as my daily driver if mine got lost or broken.

Very sturdy aluminium case, and a quality finish. The handle bar mount is sturdy and doesn’t wobble about, and mounting and detaching the light is easy, but secure. The 900lumens is a little bit too bright for normal road use.. but really useful on dark paths (like the Thames path I cycle on). However the light has different brightness levels… if you can figure out how to change them! Battery life seems good.. even when on full continuous power! Overall, an excellent light.

These lights are BRIGHT. I have the 800 and the 1100, and cannot look into the lens without my eyes burning. They're extremely bright and will light up a good amount of scenery in front of you. The battery life, however, is a little bit disappointing. They take a long time to charge, and require a lot of charging. I could probably get a few short (20-30 min) rides out of one before it is on 0%, but other lights supposedly offer more time per charge. You do get more battery life when you reduce the brightness though which I suppose would be useful if you're not riding in the pitch-black! One thing worthy of note is these lights remember their previous mode. If you set it to mid-beam and turn it off, it'll be on mid-beam when you turn it back on. That's probably expected. BUT... If you set it to low-beam and then double-click the button to put HIGH beam on, then you press the button again, it'll go back to low-beam! That means it can basically double up like a full/dipped beam - that's one of my favourite things about these. The housing on mine is aluminium but I know some of these have plastic housing. The alu housing feels solid, is not too heavy (though does feel extremely sturdy), and does offer decent heat dissipation (these get warm). The flextight bracket is actually a fantastic design. It's really simple to put on, and the lights are easy to slide on and off (though they shouldn't come off unintentionally, because you need to press a button or pull up a latch depending on your light model). Overall, except for the subpar battery life, I'm really happy with these. That's why I got two!

Upgraded from the AMPP400 version which lasted me over 2 years. This one is certainly brighter and feels more premium. 3 levels of brightness plus 2 flashing modes. No charging cable included. So 4 instead of 5 stars

I bought this November 2024. It stopped working December 2025. It is a good light but one year is not good enough for such a pricey item. I bought it off Amazon so I imagine I have buckleys of getting a return on it.

Excellent product that really holds a charge for a long time. Some great modes, strobe, full and half power. I have two of these and use them on the handle bars of my mobility scooter. As the nights start earlier, they will get a decent amount of use. They kick out quite a bit of light. Am I happy with the product? A firm YES

Great light easy to fit and remove for recharging and powerful light

Its very bright :)
