First, it allows you to be seen better by drivers on the road. You're less likely to be overlooked by parked cars or other things on the road. Second, by illuminating your helmet, motorists can see where you're looking much better and approach you more easily.
Chips On Board (COB) is a method of LED construction that has a number of advantages over more conventional technologies. It allows for a more compact footprint while delivering higher light intensity, which means you'll be seen from a greater distance. It also results in a more uniform light output. Lumos likes to call it their best LED technology at the moment.
The Lumos Ultra MIPS+ is an additional safety feature that is built into the helmet to provide extra protection against rotational movement on impact. It is also Lumos most ventilated helmet to date. They listened to feedback from their customers and paid very close attention to how the Ultra directs air through its internal ventilation system. Three huge vents were created in the back of the helmet to ensure hot air is pushed out and keeps the rider cool, whether commuting or sport riding.
MIPS® Multi-directional Impact Protection System
MIPS® is a sliding plane system inside the helmet, designed to slow down or absorb the amount of energy transmitted towards or away from the head.
