List of bicycle lights’ performance figures (lumens, runtime, etc.) measured with an integrating sphere

Sat, 07 May 2022 07:41:31 +0000

I measured bicycle lights’ performance figures such as lumens and runtime with my integrating sphere (see How to measure lumens of a light with an integrating sphere).
Below is a list with measured figures. I hope this list will help you when you choose a bike light.

The values listed on this list are not the manufacturer’s nominal values, but are all actual measured values.
In the initial view of the list, each row is in descending order of Lumen-to-Weight-Ratio (LWR).
Each line can be rearranged by pressing the item name listed in the header of the list.
You can also find lights by entering the name of the light or manufacturer’s name in the search box.

Note: When the list is viewed on a smartphone with a narrow width, all values may not be displayed.I recommend you use a PC web browser.
Most of the reviews are currently in Japanese, as they are currently being translated into English.

Item Descriptions See here for detailed explanation.

Runtime (in hours)
Time taken for the light to reach 10% of its initial lumen.
Average lumens
Average value of lumens during the lighting time.
Total Lumen Output
Total cumulative amount of lumens produced by the light during the lighting time.
(= Runtime * Average Lumens)
Weight (in grams (g) or ounce (oz))
Weight of the light including its fixture and battery.
Lumen-to-Weight-Ratio (LWR)
Total Lumen Output divided by the weight (in grams) of the light.
LWR percentile rank
Percentile rank of the light’s LWR among the bicycle lights measured so far.

Notes on data use

All measurements were conducted at room temperature between 20°C and 25°C (between 68°F and 77 °F) using new batteries.
The performance (lumens value and runtime) described in the list may not be achieved when using deteriorated batteries or at extremely low/high temperatures.
The values may change in the future due to data updates and re-measurements.
Lights that have received extremely low review score are not recommended for use, and links to the manufacturer and sales website may not be included in the list.
