- The brightest bike light currently available is the Ugoe TB-13-01. This light shines with 4500 lumens (a typical car headlight produces about 1500 lumens). It costs about $150.
- The brightest bike light that doesn’t involve a external battery is the Cygolite Trion 1300 Bicycle Headlight — it costs around $213.
At 4500 lumens, there is no doubt that the Ugoe TB-13-01 is considerably brighter than most other bike lights, which tend to output about 600 lumens on average. The Ugoe is constructed with an “aircraft” aluminum alloy and the body is waterproof. When it is running at its highest mode, the light does get very hot to the touch, and many cyclists find it too bright in that mode (see the photo below).
However, in “medium mode” (1500 lumens), the light stays cooler, and the battery lasts around four hours. A couple of potential drawbacks: this light has an external battery pack so you cannot easily snap it on and off your bike. Also, the light takes about four hours to recharge (the manufacturer warns not to leave it on the charger for more than 24 hours).
The Brightest Single-Unit Bike Light: Cygolite Trion 1300
The Cygolite Trion 1300 is one the best rated bike lights out there. Personally, I use this 1300 lumen light when I go night riding. It will illuminate a road well enough so that I can see potholes when going downhill.
The Cygolite Trion is available at Amazon for $187.
Cygolite also makes the 1700 lumen Cygolite Centauri ($230) — this light uses an external battery.
Niterider Pro 3600 Lumen Light
The Niterider 3600 Pro is a 3600 lumen light made in the USA. This light has two chambers, and each chamber contains three Cree XML LED bulbs.
Niterider have a great reputation, and I’ve found their lights to be very durable — they’ve survived a few falls onto pavement from my bike.
This light is very bright and projects a wide beam hundreds of feet. A unique feature of this light is the incuded DIY software, which allows you to customize the settings it to your needs.
Note that the light’s beam is just too bright to use in an urban area, unless you greatly step down the intensity! If you feel you’ll be doing this, you might consider the 1800 lumen Niterider, or the 1200 lumen Niterider.
The Niterider 3600 Pro is available on Amazon for about $595.
An Inexpensive 1200 Lumen Light: The Bright Eyes Headlight
The runner-up in the brightest bike light category Bright Eyes Rechargeable Bike Headlight which shines at 1200 lumens, and costs around $50. At one-third the price of the Ugoe, this waterproof light is a worthy contender. It has a 6400mAh (amp hour) battery, which is a slightly higher-capacity than the Ugoe’s 5200mAh battery. The battery is also built into the light, making it a bit more compact and convenient.
