Lumos Firefly is Great!

Lumos and Lumos Firefly are great! I ride early in the morning and need as much light as possible! The Firefly lights me up so great that I actually feel so much safer! I had an issue with it at first but Lumos fixed the situation and made it great!

Great Bike Lights - better than anything I have owned

Purchase 2 Lumos Firefly lights - came well packaged and partially charged, which was very convenient as I hadn’t decided how I wanted to charge them.
Currently using Qi charger and appears to works well, If I purchased more lights would consider charging pad for 4 lights

As I already have Lumos Ultra helmet, already had app and it was easy to pair both lights. Really like the different flashing/on patterns and the lights are very bright.

It was easy to attach to my bike with the pads supplied and love I can slot them in and out when I park up my bike in public places.

added bonus is that when I turn off my helmet lights, the Fireflies turn off too.

Excellent Customer Service

After a year of ownership, one of my set of four firefly lights had a battery problem. Lumos replaced it in a speedy and trouble free manner. Great lights and an excellent company. Thank you!
