Rechargeable Lithium Battery Pack 8.4v 6400 mAh & Pouch Bicycle Bike Cycle LED Light

Product Information

All of our lights have at least one-hour of run time at the 1,500-lumen minimum requirement, but most offer considerably more burn time at their max output, so it’s unlikely you’ll get caught short. The 900-lumen setting is more of an emergency turbo boost mode, but battery life on the 800-lumen setting is excellent, providing just over two hours of run time.

This can be easily resolved by applying a small amount of silicone lubricant to the outside surface of the battery connector. Our bike light reviews are mainly focused on front lights that will enable you to see where you are going on unlit cycle paths or rural roads.We also had concerns about the long-term durability of the mount, but Hope’s after-sales support is generally very well regarded. However, high power beams tend to last just an hour or two at most, even for the most premium lights. A super-bright light that only has enough battery power to put out that headline figure for half an hour isn’t likely to be particularly useful, especially if you’ll need to use the most powerful setting for extended periods. There’s an ambient light sensor that puts the light in standby mode during the day so you don’t burn through the battery while it’s still light, and you can choose to vary output continuously rather than via the eight set modes. Helmet lights also tend to be ‘spots’, providing highly directional, concentrated light where you’re focusing.

Usually, the mount is tightened to the bars using an Allen key because head units can be quite heavy. If you need to ride roads or shared paths to reach your trails, you also want something that can be dimmed to not blind oncoming traffic. Probably made in China like the rest of them, unless it's one of these or similar BT-70791CK, BB-2590/U 7. The bar mount provides a stable beam and is easy to hook up to the bars, while the battery pack secures firmly to the frame with two velcro straps. In our tests, we timed each of the lights on their max setting to find out just how long the juice will last.

These battery packs are sometimes designed to strap straight to your frame but they can be awkward to mount and can get filthy in the wet/muddy conditions commonly found on the longest nights of the year. There’s plenty of power on offer from the two LEDs (plus a daytime running light strip), which can be operated independently. Some brands promise maximum capabilities; A huge amount of light in combination with a long lifetime. A built-in accelerator mode detects when you are slowing down and increases the brightness of the light. The high IPX 7 waterproof rating means that it should be able to withstand the worst of winter weather.
