The Blackburn DayBlazer 125 is the big brother of the DayBlazer 65. It packs a bigger punch and longer burn times, with the same easy-fit mechanisms, at a small extra cost on the scales and a slightly bigger extra cost to your wallet.
- Pros: Very bright, easy-fitting
- Cons: Not as good value as the DayBlazer 65
In terms of how you fit and use the DayBlazer 125, I could simply refer you to my recent review of the smaller 65 lumen version. It features the same style rubberised mount that can mould to fit all kinds of seatposts and seatstays, which sits over a sprung clip for fitting to backpacks and the like.
Secure and easy to use, it makes fast fitting and removal a doddle, while the single button you use to turn it on, off and cycle through modes is precisely the same too – a simple cycle-through system with no mode memory. Thanks to the added brightness, Blackburn has included a lower static light setting at 50 lumens (the equivalent of the only static setting in the 65 model), while topping out at an impressive 100 lumens in the high level.
The lithium-ion battery has near enough double capacity (3 hours versus 1:30 hours in the 50 lumen static settings), with a max output of 125 lumens in the 'high flash' mode. In this mode you also get 3 hours burn time, which I reckon is just enough for a decent-length winter ride in typical wintry gloom, while you can use the still-bright low setting for 6 hours if you're feeling particularly hardy.
Recharge times are up slightly too, but at just under three hours from empty to full, it's very convenient to just pop it into your powered USB bus while at work or at home and have a fully powered light the next time you use it.
The light is emitted from three LEDs in a longer array body, while the power button is positioned atop the unit rather than the middle. The extra size means weight has more than doubled, but at 87g it's still hardly an issue. The only potential thing to bear in mind (compared to the smaller unit, at least) is if you run your saddle height low and you want/need to mount it to the seatpost, you might not have enough exposed post to fit it on.
The 'TIR' lens over the LEDs points the light simultaneously backwards and downwards to compensate for the natural slant of mounting it on the seatstays, and there's improved side visibility too thanks simply to the greater brightness output.
Build quality is excellent, with a quality aluminium body this time out, a tidy-fitting USB cap and an IP67 waterproofing rating, which is more than enough to stand up to heavy rain or a five-minute deluge/half submersion in my shower without any concerns. Blackburn also backs it with its limited lifetime warranty too.
Aside from the weight, the other downside is the added cost. At £44.99, it's a good £17 more than its smaller brother, which if I'm brutally honest does everything you really need from a bright rear light. That said, more power is always handy when you're on shorter urban journeys, while the extra battery life that the larger unit is capable of for longer rides is probably the most compelling reason to swallow the cost.
However, for just a fiver more you could have Lezyne's Strip Drive Pro 300, which can both out-power and out-last the DayBlazer 125 (in certain modes), while keeping much of the functionality.
Simple functionality, great brightness, acceptable battery life and good build quality

Tell us what the light is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Blackburn says: "Take the lane with the confidence you're using the strongest tail light we've ever made. Featuring 3 focused LEDs, 270 degrees of visibility, and the 125 lumen BLITZ daytime running mode, the DAYBLAZER has all of your ride needs covered. Also, because of the narrow profile of the light and our unique mounting bracket, the DAYBLAZER 125 tail light can be mounted to just about anything you can think of from round or aero seatposts, to seat stays, to a rear rack, or your back pack."

The alloy body is solid, and everything looks very well made.
Very easy, and four modes is enough.
Super-easy to use and the recessed metal clip is handy too.
No ingress to report so far.
Not outstanding, but enough for one use-then-charge if you use it for a long weekend ride.
The LEDs and lens direction is effective, and the brightness is reassuring in busy or dark conditions.
Can't fault it thus far.
87g is a jump over the 65 version, but you still don't notice it in the real world.
Lezyne's Strip Drive 150 is £32 rrp; for £5 more you can get Lezyne's Strip Drive Pro 300.

If you're not convinced that the DayBlazer 65 will meet your brightness or battery life needs, the 125 version probably will; it's not as good value, though, so it loses a mark.
