Works well, good features, some bugs but good customer experience

It's a rather expensive product, but they're probably the most feature extensive bike lights you can buy. Especially the signaling (blinker) function makes it worth it for me, although it's best used in combination with their blinker remote (and the sadle bracket for the rear lights), addin to the price. The overall experience is very user friendly: the pairing process (both between the lights as with your phone), the useage and setting the lights' modes on the app are all intuitive and fast.

I experienced some bugs with the app at some point, but they communicated a fix via email and it's clear they're working on it.

The most negative point for me was that one of the lights started acting up after trying to turn it off (by long pressing), a subsequent firmware update didn't go through properly (it never indicated it finished updating), and after a few more uses the light got bricked (or something): when connected to the charger, it showed the small green light indicating it's fully charger, but it couldn't be turned on anymore. After explainig the problem via email, I got send a new light free of charge within 2-3 weeks of my first email.

So overal I'm very satisfied with my purchase.

Superb device

But the charger is worse, because it always causes overheating of the Firefly. It works better by charching it with Apple Mac-Safe.

Can each Lumos Bike Light have different light colors or functions?
Yes, it’s an all-in-one light! One Lumos Bike Light can be used as a front or rear light and with or without turn signals. You can change the function of the light as often as you like within the Lumos Companion App.
How bright is Lumos Bike Light?
We do not have an official Lumen rating on our products as this depends on many factors, like amount of lights, light pattern etc. Here's why.
Where can the bike lights be mounted?
Lumos Bike Light comes with one universal mount, silicone strap & velcro strap and 2 paddings so it can be mounted on several types and shapes of handlebars, the seat post, rear rack, bike trailer, backpacks and even your body. Just note that the silicone strap stretches up to 15cm (~6 inches).
How can I activate the turn signals?
You can activate the turn signals with the Lumos App. They can also be activated by the Lumos Remote (optional), which can be included with your perk an add-on.
Does it come with the Automatic Brake lights?
The Lumos Bike Light comes with an optional brake light feature. If you wish to have the automatic brake light feature, then you need the Lumos Remote that has a built-in accelerometer required to activate the brake lights on your Lumos Bike Light.
How long does the battery last? What is the charging time?
With a 500mAh rechargeable battery inside, Lumos Bike Light will last up to 35 hours, depending on the settings. Choose a hi-vis mode for maximum visibility on the road or battery-saver mode for the longest-lasting mode of up to 35 hours. It takes about 3-5 hours to fully charge your Lumos Bike Light, and you can check the battery level in the Lumos App.
Why a wireless charger?
As part of our effort to make the bike lights as durable and weatherproof as possible, we decided early on that we would do away with a charging port and push for wireless charging. You can charge one Bike Light at a time with the Lumos wireless charger or use your own universal charger. Bike Light uses Qi, the global standard for wireless charging, so it should be compatible with most chargers on the market.
Is it weatherproof?
Yes, you can always bring Lumos Bike Light on your rides. Come rain, come shine. Thanks to the wireless charging, Bike Light is water-resistant and can easily be mounted on your bike, trailer, backpack, you name it.
Is the Lumos App compatible with Android and iOS? Can 1 phone control everything?
You only need a smartphone and the Lumos Companion App to control all your Lumos Bike Lights and/or Lumos helmets. You can change the light settings in the app, which is compatible with Android as well as iOS.
Is Lumos Bike Light compatible with my Lumos helmet?
The bike lights are compatible with the Lumos helmets: Kickstart, Matrix and Ultra, and the Lumos Remote. You can simply sync your Lumos products in the Lumos Companion App.Note: Lumos Bike Light is not compatible with the (round) Remote Lite.
I don’t have a Lumos helmet. Can I use the Lumos Bike Light?
Definitely! You can use one or more Lumos Bike Lights with or without a Lumos helmet.
Are the (flashing) lights allowed in my country?
Bike Light has different light settings so you can always set them on the solid mode when needed. While in most areas flashing lights are allowed, traffic and (bicycle) lighting regulations differ in each country. We recommend checking the regulations of your area with the local authorities.
Do the lights meet the requirements of the StVZO in Germany?
At this moment it does not meet the StVZO requirements as flashing lights are forbidden in Germany when mounted on a bike. That said, flashing lights are allowed in traffic for example on helmets, backpacks etc. as long as they are not attached to your bike directly.If you’re cycling anywhere other than German roads, you do not require a light that's StVZO certified.
Does it have any certifications?
Naturally! Bike Light complies with the electronics regulation standards and is certified accordingly. Lumos Bike Light is certified to the relevant requirements as set out by the FCC in the US, CE in EU, and UKCA in the UK.
