The NiteRider® Sentinel 250 is designed to increase cycling safety by way of 2 varying flash patterns and 2 steady beams (High/Group Ride Mode). Behind the durable red lens and casing are two powerful LEDs that emit 250 lumens in the brightest Daylight Visible Flash setting, allowing you to be seen day or night. For enhanced safety, the Laser Lane modes (3) are designed to project ultra-bright laser lines on the ground. This creates a virtual lane for the rider, further increasing visibility.

Bike Lights - How Many Lumen Do You Need?
Bike lights are rated in Lumens. A Lumen is the measurement of the total visible light emitted and is commonly used for all kinds of bulbs.
One thing worth noting is that most lights advertise their headline rate. Packaging may say 1000 lumens. Reading the small print they might only do that for an hour. That light may run 500 or 600 lumens for 2 or 3 hours. So it's worth buying a light with more lumens than you need to get decent running times.
There is no fixed agreement on how many Lumens you need for a bike light as it depends on the type of cycling you are doing. As a rough guide we say that:
- Daytime running lights = 100+ Lumens
- Urban commuting lights = 50 to 200 Lumens
- Rural riding lights = 400 to 600 Lumens
- Trail riding lights = 600+ Lumens
Please note: Manufacturers can sometimes change the specification of the products from time to time.
