A 5000 lumen bike light that weighs just 49g is crowdfunding on Kickstarter

Hello Von, 
I'm Enrico the founder of this project.

As explained in the campaign, Focus is not intended to be used hours at 5000 lumens. Focus can emit a burst of light @ 5000 lumens. For example, you can flick your high-beam in specific situations (for example, a blind turn, a dangerous situation, etc...):

More than that, Focus can sustain a low light intensity for more hours.

Cheers

I'm impressed; this light is something I've been wanting for years. Congratulations.

Thank you! Have a look at the campaign if you want, we just reached the goal by we're setting it for new stuff:

Why not? every bike light I've used has micro-USB.. works for me.

Because it's old fashioned and sucks. Needs USB C.

Yup, that's true, and that's the problem - because everything else* has moved over to USB-C. So I have to swap and juggle cables, remember to pack that extra cable on travels, etc, just for the bike lights. It's a faff to be honest, and more than a faff when I forget. So given a choice, I ain't buying no micro-usb nuffink no more!

* except iPhone, but who has one of those?

Hello, 

thank you all for the feedback. We decided to move to the USB.C. No problem at all! You can have a look at the updates here: https://www.bybtech.it/focus

Are they for real going to use micro-USB for this device?

Hello, 

we'll use the USB-C. We received a lot of feedbacks about it. No problem at all.

Hi Enrico, the kickstarter says your light will do 800 lumens for 6+ hours, is that correct, and the chanrging time will be approx 15minutes?

If not could you tell me what time the 800 lumens brghtness will run for? and what brightness it can do for 3 hours?

Hi, 

thanks for pointing it out. Thanks to its compact (& drones derived) battery we can provide a super-fast charge. Basically, you can charge your light when you dressing for the ride. 15mins to top-up.
We have a smartphone app that let you choose the exact amount of light you want (there's a scrollbar from 0 to 100) and the corresponding battery duration is live updated. I can try to attach a screenshot of the app here: 

In the current setup, we are able to range the low-beam lifetime from 1/1.5h to 6h+. The intensity ranges from 200 to 800 lumens. You can fine-tune and customize your intensity vs battery duration according to your needs.

You can see the progress of the campaign here and text us messages from here as well: https://www.bybtech.it/focus

If you need further info, drop us a line

Cheers

Thanks, I need 3-3.5 hours at 500+ lumens so This might not be for me, I'd be interested in a bigger capacity version if you ever do one.

Hi check12,
the light intensity to do 3 hours is actually set to 400/450 lumens.
Considering the super-compact it's a lot. We're confident of increasing the battery life slightly. 
You can always link Focus to an external battery/power bank and selecting the "External battery option" from the smartphone app.

Correct, flashing lights are not allowed but a recent change to the German law means StVZO-approved lights can include a high-beam mode. In other words, they enable the rider to switch from the StVZO cut-off setting to a more powerful full beam when needed.

Ah, good point!

Isn't there something a bit odd about a pricing model where two units (€279) cost more than twice as much as a single unit (€125)?

The Early Bird Duo pledge is €229.

(My advice is to not go for electronic based KickStarter products unless it's a known and trusted company - though they seem to have produced BYB Telemetry successfully).

Ah - it's been corrected, though only the Euro figure so it now says "A backing of €125 (~£105) gets you a single Focus One unit, and you can get two for €229 (~£232)." I know we're not doing great but don't think the pound has quite dropped below parity with the Euro yet!

Does it not depend on how and where the beam is focused (and the angle it is fixed to the bike at) ?

I might be getting this wildly wrong - but surely if you have a 5000 lumen light to be seen, only to have to point it downwards to not blind people, couldn't you simply have a lower lumen light pointed straight ahead?

In short - isn't this all a bit pointless?

I think the general idea is, is that you wouldnt be running it at a constant 5000 lumens at all. Only using it for flicking your high beams like when youre behind the wheel of a car and either giving way to another vehicle or saying thank you etc etc.

Most of the time you'll be using it at the lower power ranges 300-800lumens (though i dont think the battery will actually last as long as they claim)

Saying 'thank you'?

.

I'm a cyclist: how DARE you?!!

I've never really understoud this - saying "thank you" to another motorist by temporarily blinding them. I find a better option is to blink the lights off (i.e. drop to side lights or daylight running lights).

One change I would like to see made to highway code is to change the advice in rule 115 - there's no need to have dipped headlights turned on at night to be seen on a lit road. Side lights or daylight running lights are more than sufficient. Generally cycle lights only need to be so bright, because they need to compete with the glare motor vehicle headlights (which results in other lights being almost invisible). BTW I like how some motor manufacturers have picked up on the fact that their daylight running lights are brighter than their indicators, and now turn off the light on one side when indicating.

*edit daylight running lights probably produce more glare than dipped headlights
