The OLED display that gives you mode, run time and recharge information (Image credit: Guy Kesteven) The lens of the Exposure Sirius Mk9 Daybright bike light focuses the beam into a super bright spot that over shines all other similar lights when compared. This is surrounded by a good spread of light on the peripheral to enhance road and hazard perception, while also delivering excellent side visibility. Patented circuitry within the light will reduce power to the LEDs, if they go beyond the optimum temperature, keeping the light as efficient as possible to maximise output and battery capacity. Once the light has cooled, the power is automatically restored. In The Box

Once the light has cooled, the power is automatically restored.

It’s important to note that when shopping for Lights products, it can be tempting to go for the lowest price possible, but be wary of retailers that offer prices that seem too good to be true. Some less reputable retailers may sell counterfeit or low-quality Exposure Sirius MK10 Front Light with DayBright, which can be dangerous and not perform as well as the genuine product. Choosing a reputable retailer like Chain Reaction Cycles can help ensure that you’re getting a high-quality product at a competitive price.

Options for everyone. Depending on your needs you could have less complexity but the trade-off would be someone else not getting what they need. Some lights take time to get to grips with and their operation isn't memorable, but I didn't find this to be the case with the Sirius. Exposure does sell a smaller clamp designed for 25.4mm to 31.8mm bars, which would be a much better inclusion as it opens up compatibility for older, skinnier handlebars.Despite the light’s visual bulk and relative high weight, it was impressively stable even over the roughest terrain I could find; not shaking, slipping or coming loose at all. The rear emits a powerful 75 lumens, or up to 120 using ReACT technology, which is an intelligent system that meansit flares under braking and adapts to ambient light conditions; brightening in well-lit areas and dimming when you move into darker or shady zones. Quality Exposure Sirius MK10 Front Light with DayBright will last much longer and perform better than their cheaper counterparts. They are typically made with higher quality materials and are designed to withstand the wear and tear that comes with regular use. Investing in a high-quality Exposure Sirius MK10 Front Light with DayBright means that you won’t have to replace it as frequently, saving you money. Burn time for the power is good but not the best and not using USB-C for the connections makes it harder than it needs to be.

Various programs in the lights can easily be selected to offer a choice of run times and modes so you can find the right one for your ride, be it an all-night adventure or an intense blast. Operation is via a rear mounted button and offers a traffic light system to indicate which mode is engaged, it then switches to indicate battery level. The Daybright mode is an interesting feature that, as the name suggests, is intended to get you seen while riding during the day. It's a pulse pattern that's really bright and noticeable from a long way off – we're talking hundreds of metres – even on a sunny day.The mount isn't aero-bar compatible but fashioning something out of a silicone/rubber strip isn't out of the question, or you could fork out a fiver for Exposure's specific aero-compatible mount.

Like many of Exposure’s lights, the Strada MK10 SB features the Optimised Mode Selector (OMS) function. The optimum number of light settings is always a bit of a balance – whilst it’s nice to have a range of choices, if there are too many it can make switching between them quite a pain. Whether the additional 50 lumens makes a huge difference over the MK9 is debatable, but extra lumens are always appreciated, and Exposure hasn't upped the price. The light has a 7-hour battery charge time and a maximum run time of 36 hours, depending on the mode selected, and there's a fuel gauge to alert you to the remaining battery level so you don't get caught out. In the boxThe Exposure Sirius Mk9 Daybright bike light uses the brand's own OMS programmable mode setting to enable the end user to set the power and number of light modes dependent on preference. Patented circuitry within the light will reduce power to the LEDs, if they go beyond the optimum temperature, keeping the light as efficient as possible to maximise output and battery capacity. Once the light has cooled, the power is automatically restored. Reakt The point of all this is to keep brain power and guessing to a minimum when you find yourself at the limit while also offering a ton of choices. When riding, each press of the button will show a coloured LED. Green for high, amber for medium, and red for low. The main display panel also shows the mode you are in and a countdown timer. In case you forget which program you are in, the display shows that when you turn the light on and if the light is upside down, the display swaps direction. Exposure Sirius Mk10 the ultimate “to be seen” front light, now with the output increased to 900 lumens to light the road ahead in the dark nights. The Sirius hits the sweet spot for power to weight, housed in a CNC machined aluminium body that features 240° front and side illumination giving the flexibility to be used for the daily commute or longer rides.
