Specialized Flux 1250 Headlight review - floodlight function is great for the road, less so the trails

Spreading its lumens over such a wide area does light up the roads nicely - although that does mean the spotlight isn't as bright as other 1,250 lumen lights

Cycling Weekly Verdict

A very effective bike light that has both a decent spotlight for range and a great floodlight to illuminate the entire width of the road. Battery life is decent and charging is quick, although a USB-C port would be preferred to Micro USB. Weight is a little heavy for helmet mounting, but bar mounting is very good with the light clip being secure yet easy to remove. Value-wise it falls behind others which offer similar performance for a smaller price. However the floodlight is a feature that's not often found.

Although Specialized is primarily a bike brand, it has managed to expand its remit to such an extent that its helmets, shoes, and saddles have transcended the bikes - you'll see people using them irrespective of what bike they might be riding.

Specialized's lights range, it's fair to say, hasn't permeated the public consciousness in such a way. But should that change? How good is the Specialized Flux 1250 Headlight - and how does it stack up against the best bike lights that we've tested and reviewed?
