Zuverlässigkeit

Die Firefly light sind eine tolle Ergänzung als Blinker oder Zusatz als Front. und-oder Rückleuchten...
Als Blinker sind sie leider nicht zuverlässig! Es kommt öfter vor, das das Blinken nach Schalterbetätigung nicht ausschaltet, was besonders für hintere Blinkleuchten nicht ungefährlich ist. Da man es beim Fahren auch auf Grund von evtl. Seitentaschen nicht sehen kann. Man blinkt weiter... was zu Missverständnissen mit anderen Verkehrsteilnehmern führen kann und auch Unfälle provoziert..

Mostly awesome!

I haven't gotten the auto brake light to work yet; otherwise, I love all other features. Battery-wise, I get about an hour of use on the boost setting, which is just enough for my daily commute to and from work. The lights are strong and powerful, both in material and lumen output. They're not the brightest but very reliable. Sometimes indicating can cause problems, but with a few right and left indications, it auto-fixes itself, or just double-tap a fully functional light, and the out-of-sync light will sync back up with the rest.

I wish they had an emergency stop feature. It could maybe be incorporated through the phone's gyro or an updated controller with an extra button.

Charger not included; any Qi wireless charger will do just fine. I would strongly recommend buying the 4x charger dongle if buying four or more lights.

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!

There must be a reason why I bought another one ?

At first I buyed 2 Lumos Firefly. Why I buyied the third? Because it is a chameleon light and allows you to do what other lights cannot do.

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.
