    Outstanding helmet. Would have given 4 stars because instructions were ~ none; no transformer with the charging cable; on/off switch difficult; the Red version sadly not available, but still a great helmet. MIPS I believe is worth the extra and the light weight and fit are great, the lights are bright and the turn signals amazing. Good value for the money.
    Mo. later update: Minor problem: 1. with a recumbent, bumpy ride, the rear Mips inner part knocks loudly against the outer, need some adhesive foam tape. Lumos agrees. 2. The rubber charging cover difficult to lift, better after ~20 uses.
    Some might need a small visor.

    The front, and rear lights make riding safer. And a big plus is that it comes with a turn signal that activate the rear helmet lights. The only problem is that the description wasn't clear that it doesn't include a visor. Which must be ordered separately and at present the visor option is out of stock.

    The Lumos Ultra helmet is available at 2 prices. The lower price is WITHOUT MIPS. The higher-priced helmet is WITH MIPS. I opted for the slightly more expensive with the additional protection, which is described as reducing helmet movement and helping to reduce brain movement and subsequent injury in the event of an accident. The additional protective material is inserted inside the helmet and you have to apply this yourself when the helmet is first set up to be used. It's easy and small patches of velcro keep it in place.

    The helmet itself is lightweight, not too bulky and easy to adjust. The lighting on the helmet at the front does the job of helping increase your visibility and can be set to remain on, or flash. I would say the light is not bright enough to replace a handlebar-mounted light if the thought crossed your mind. The control for the helmet light flashing pattern can be controlled via an app, available for iOS and Android. There is a charging port and button to operate the light on the rear of the helmet.

    The rear lights look great - very neat and bright, again, increasing visibility on the road. The rear lights also operate as indicator lights, left and right flashing. These are controlled via a supplied add-on for handlebars and are easy to use, with a small beep emitted from the helmet to let you know they are in use. Very handy. The button controller is small and easily attached to the handlebar. As with the front lights, the rear lights have customisation options via the phone app. The left/right indicator control comes with a 2032 battery and is easy to fit.

    The phone app also provides you with feedback on the batter level of the helmet lights and Lumos actually offers firmware updates via the app, which is connected by Bluetooth to the helmet. The supplied USB-A to USB-C cable will charge the helmet from your typical iPhone or Android charging plug.

    FYI - There is an optional device, compatible with this helmet, which can be purchased and I think uses an accelerometer to provide 'brake' lighting, to alert anyone behind you that you are slowing down.

    The helmet is breathable and feels sturdy, offering a level of comfort and reassurance when you're cycling. It's good value for money in my opinion, and hopefully, I will never have to find out just how good the helmet protection can be.
