Splitting the difference between the previous Flux 800 and 900 the Flux 850 gets the game-changing Mode Shift found on the Flux 1250. This means there are three steady modes all using both the wide and spot beams. Go from Steady Low to Steady High in a single push without cycling through a flash mode. Press-and-hold for two seconds and you get into the secondary modes: Steady Flash to be seen in busy urban environments Flash Mode for endless runtime and two Flashlight modes with 10 and 20 hours of runtime for hanging around the campsite or when you forget to charge your light and need to conserve the last few percent of battery life to get home.
IPX7 waterproof means this light can survive being submerged 1 meter deep for 30 minutes. No it's not meant for scuba diving. But is can handle anything you can throw at it on two wheels.
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:
Specialized is one of the best-known quality bike brands in the world. Started by a group of riders in 1974. A fact which has guided their decision making ever since.
" Made for riders, by riders."
They strove to make the best quality tires when quality tyres weren't around. When people wanted to ride cruisers in the dirt, they made the first production mountain bike. When roadies wanted to go faster, Specialized doubled down on carbon and built their own wind tunnel.
Bikes like the Allez, Rockhopper and Stumpjumper have developed followings and reputations of their own. Specialized has a reputation for making high-end, high-quality bikes. Specialized bikes always look great with high-quality paint and sensible sizing hel0s you get the right bike each time. If you buy a Specialized bike you can be guaranteed it will do what it is supposed to and will last.
Please note: Manufacturers can sometimes change the specification of the products from time to time.
