Ken at Power in Motion gave me this 900 lumen LED bike light to try out. Naturally I said yes! My reference lights are a pair of Dinotte 200L-AA that are rated at 200 lumens each and run on 4 AA rechargeable batteries. I’ve always thought the 200L’s were very bright so I was interested to see what 900 lumens was like.
This light kit consists of a LED light engine, proprietary rechargeable battery and AC charger. The box the light comes in is easy to open with a flip top and magnetic latch. That’s nice because typically I recycle product boxes because they aren’t very easy to open/close for day to day use. I’d actually keep this box to store the light when not in use and reuse is better than recycling by a long shot.
The light engine features a SSCP7 LED and simple reflector. Note that the optics are not focused so you get a cone of light that extends from the light engine.
The light engine case is waterproof and features a integral heat-sink to keep the light cool. There is a single control button on the back that cycles between high power steady, low power steady, flashing high power and off.
I have no specs on the proprietary battery pack other than a stated runtime of 3hrs on high steady. I tested this and managed 3hrs 10mins with my unit. Low steady should run for a lot longer and in flashing mode I imagine it will be a week or more of night riding before you would have to think about charging. It took me 4hrs to charge the battery from empty to full with the included AC charger.
I should note it looks like the light engine may draw a small amount of current when off [same as the Dinotte] so I’d recommend you unplug the battery pack if you aren’t using it so you don’t drain the battery unnecessarily.
The plug is waterproof and easy to use. Both the plug and the wiring look solid and should be robust enough for long term use. Ken mentioned that this light can be connected to one of his e-bike kits so you can run it from the main e-bike battery. That would be a convenient option for a electric bike commuter.
The battery come with a nylon case that can easily be attached to your bike via a velcro strap.
The test light engine mounts in a similar fashion to the Dinotte 200L using a rubber o-ring. This is a very versatile mounting method that has lasted several years of regular use. This means the light can be swapped from bike to bike in seconds without tools and the beam can be aimed up and down on the fly. Of course this type of mount means the light can be stolen easily so you’d be advised to take it with you when locking the bike. You get a large and a small o-ring with the light kit so you should be set for just about any diameter bar.
On the whole I really like these o-ring mounts. The convenience of use outweighs the security issue for me.
The test light is attractive and looks well made. As you can see from the photos it’s quite a bit bigger than the Dinotte 200L, but at 4.5 times the rated lumens maybe that’s a necessary thing – the Dinotte 800 lumen light is much bigger as well. The Dinotte case is a work of art to be sure, however, it comes at a cost. The 900 lumen LED tested here sells for $145 CDN at Power in Motion compared to $229 USD for a 200L – LI proprietary [lithium battery version] or $351 USD for a Dinotte 800 lumen light.
The 900 lumen test light is controlled from the rear via a single button that is illuminated to show it has power and switches to red to indicate a low battery. The button is not as easy to use as the Dinotte button because it doesn’t protrude from the case as much, but I was able to change settings with a gloved hand no problem.
The light engine and battery weigh 340 grams [12oz] – light enough I didn’t notice them on my bikes.
Here are two pictures to try and compare the 900 lumen test light and the Dinotte 200L. This is not an ideal test as my camera adjusts settings differently between pictures, but it was the best I could muster on short notice. In real life the difference is even more dramatic. I have no way to measure the brightness of these lights to verify the stated lumens, but I can tell you the 900 lumen light is much brighter than the Dinotte 200L and illuminates a much wider area. This means you’ll see more of the road both close and far than you would with the Dinotte 200L. For higher speed night riding I often use two Dinotte 200L’s one aimed low and close to illuminate the near section of road and one aimed higher to illuminated the road further away. With the test light only one light would be necessary to achieve the same result.
Keep in mind I’ve only been testing this light for a couple weeks so I can’t speak to the long term durability of the unit although the construction leads me to believe it will be robust. I am thinking about buying one to test over the next year, but I have a some existing lights that meet my needs and other bike spending priorities…not to mention living so far north it’s already light until 10pm+… so I haven’t made a decision yet. This light is definitely a great value which is making me think it’s worth owning.
- the test light is well made
- the price is excellent
- the light is exceptionally bright
- the battery provides 3hrs on high steady
- the mounting system works well

Now this is where I would typically rant about the need for focused optics in bike lights like they have in Europe. However, nobody selling bike lights in North America seems to care so I’ll spare you the diatribe!…=-) I will say this – be responsible with your high powered bike lights. Consider other MUP/road users and don’t blind people with poorly aimed lights.
Adrian [a blog reader] mentioned he has some waterproofing issues with his battery pack in a similar LED light. So the investigative reviewer in me wanted to try out my test light in the wet. So I placed it on a shelf in the shower and hit it with a full force water barrage for 10 mins. I occasionally picked up the light engine and ran it through the various modes to ensure it was working fine. The light worked great and exhibited no problems from being wet or sitting in a puddle of water.
