This bike light has three sets of LEDs and four modes: 10 LEDs inner ring 17 LEDs middle ring 26 LEDs outer ring
The first three modes lights additional rings, the fourth mode flashes all 53 LEDs.
With a fresh set of three Akaline AA cells the light consumes:
10 LEDs 175mA 27 LEDs 550mA 53 LEDs 880mA
With mid-quality NiMH cells I measured 10 LEDs 155mA 27 LEDs 420mA 53 LEDs 670mA
The battery voltage and current sagged quickly in the all-LEDs-on mode.
A significant advantage is that this light uses lower-cost AA cells instead of AAA cells. And with this current draw you'll be concerned about capacity and cost.
The light is visually interesting, with a dramatic array of LEDs on a 55mm diameter mirror background. The array is easily seen through the flat clear plastic lens on the front.
The handlebar clamp is 1"/25mm nominal, with a clamping range of about 3mm -- not enough for a larger or smaller bar.
In 53 LED mode the high current caused the batteries I was using to drop in voltage pretty quickly, reducing the current. The batteries would likely last noticably less than 2 hours -- pretty much unacceptable for most users.
The handlebar clamp may have been designed for a smaller, lighter lamp. I'll add to this review if it fails in use.
If you consider power-hungry 53 LED mode reserved for occasional use, or like the look of a large array of LEDs, this is the light for you. Otherwise a smaller, lighter model should be considered.
