Customer Reviews

Exposure Sirius Mk1 Front Light 4 5 21 21
Really, really bright light. Part of my cycle home goes through a completely unlit field. My old front light wasn't up to the job so after a bit of reading, picked this one up. It's bright. No, that's not quite correct. It's very bloody bright! I now have absolutely no problem with either finding the path through the field or spotting less luminous individuals/dogs/potholes. As far as front lights go, it's the brightest one I've used on a bike. USB charging is handy, but I would have preferred it used a standard usb to mini-usb cable since those are much easier (and probably cheaper) to replace if you lose it. I'm also a little concerned about the handlebar clip. Compared to the light, it feels a little cheap/flimsy. Going over a bump means that light can sometimes move around. Not a major problem for me, but if I was doing anything more energetic than commuting it'd probably become quite annoying. While the light feels good for the price, the clip doesn't match up. Overall though, very happy with it. It's very bright and feels like it will stand up well to the occasional beating that all my bike gear goes though. Well, the light will, but I think that the clip will need replacing much sooner. 18 October 2013
Good to be seen by, average for seeing with For the money this is a good product. Its good for making you visible , particularly in the flash mode. However for visibility of the road this is OK (not brilliant). 29 September 2013
Excellent small light This is a great little unit. Bright enough for all general road and bunch riding. Only downside is it doesn't have a long burntime on high - but low is more than enough for most night riding. 15 September 2013
Very disappointed... Have been attempting to charge this light over several days via the supplied USB cable, but the light isn't holding it charge, Had high hopes for this well built, stylish light and loved the fact is was made in Britain. Hope this is rare occurrence and the replacement will be what I originally expected. 10 September 2013

Answer: 
Yes. Use a phone charger with USB plug and plug in the wire that comes with the light. Works great :-)

Answer: 
The difference is the lens. The Mk1 has a narrow pencil style lens, the Mk2 has a new lens that adds a nice sideways flood of light.
