Worlds brightest Bicycle light - 1400 lumens

[mulki]

Just saw this on Gizmodo:







The article says that it uses "7 high quality LEDs". No mention of type of LEDs used.

Cost $ 1185.

Edit - Forgot the article link:

Read the archive... It’s Lupine Betty 6/12 not 1400 lumens – they take this value from SSC datasheet - but about 1100 lumens . So still the “brightest” is CayEye Stadium 3 – proved for about 1600 lumen power HID if I remember correctly...

Has anyone made a homebrew LED setup that rivals these?

I made a couple with 6 SSC P4 led's that would be close to this. Cost me around $200 to make each.

Hendo: Nah the minT is way too flash to qualify as a "homebrew".

Brent: yeah thats what I was looking for. Fantastic.

Might as well get this...

I think Wayne at Elektrolumens.com could definately make LED lights better and brighter than that one(and probably cheaper, too).

And yet it is! Mount two of them for six emitters, and you can even combine the types of beam you'd like. It is all about the money at this point.

As for the one at the top of this thread, I have no idea how they plan on keeping that thing cool at 1A times that many emitters!

[SemiMan]

Can not believe I am saying this in this forum, but this seems like expensive overkill with less than stellar results. I love my LEDs, but if I want that many lumens, I think today I would stick to HID. I must admit the dimmability and long life are really attractive, but I think I would go with single LED or two low cost for low power usage and then back it up with HID. I will give the nod to LED for robustness, though HID tends to be relatively good compared to halogen.

Maybe in this year you have a right. However, when led's will achieve 160 lumen @ 350mA then 4 led bike light consuming 10W will give you 1000 lumens. Then there will be definitely no place for HIDs on our trials .

I also have a homemade 6xSSC bikelight. For 1A each there is approx 21 Watts on leds. A simple 50x50mm heatsink is enough when in use. Headwind makes a perfect active cooling. It is barely mild even after twenty minutes of 21 Watts use. But without forced air convection, on my desk, it becomes hot (cannot touch the heatsink) within 1.5-2 minutes.

got Cateye Stadium, Niterider HID Storm and ARC HID.....

Cateye is retired due dead batteries. super BRIGHT when it was going. Cateye was actually too bright, had to be careful not to blind cars. now using HID storm on handlebars and ARC HID as helmet light combo.

for car brightness levels and super long runtimes (8x18650 pack). HID is hard to beat...

HID offer also other advantages: The tiny size of the actual light source makes it easier to distribute the light like you want it.

[Szemhazai]

You can place 4 leds on square 4x4 cm using 4 different kind of optics... Maybe HID head is a bit smaller but when using led's you will get the beam pattern that will better suit your needs I think.

[diff_lock2]

My main problem with led's for seeing (not to be seen) is that i just cant... with Incan i can see much more depth on and off the road. And i feel like the incan strains the eyes less.

Oh and its a fraction of the cost.

this one may be less bright, but it's made with some thinking. It does not blind cars as the beam is cut of at a certain point. so the beam profile is not a round beam, but more like a circle which was cut in the middle.

/edit
should have looked at the link before posting

[znomit]

Aren't any problems with the colour of LEDs outweighed by the fact they are putting out 3 times the light (vs halogen)?

[diff_lock2]

What i love about that light is the beam pattern, it was designed to see the road, and then you can alter it to flood for off the road. But the price is just over the top for ME. I am sure the product will match the price.

Well my 20w IRC at 14v is putting out close to 1000 lumens... i could be VERY wrong though.

LOL, thats not the brightest bike light, i made a thread a couple of weeks ago about the brightest bike light, check it out, and heres one of the links to the light http://trailtech.net/SCMR16_helmet_light_kits.html

Close, but not sure how close. I make lamps and sell these on eBay. The lamp I use is fitted with a Philips Master Line ES MR 16. I run this on 15.6v NiMh pack. Light output is fantastic, but I can't compare it against anything. Rough calculation says it puts out over 100w equivalent light.

By the way, anyone know where I can get teh best LED MR16s for may lamps?

you should post details here... loads of cpf's are bikers

I was thinking of modding a cree-based headlamp or bikelight for use as a on-camera light for videography..
Any suggestions which one to use ?
It just has to have a spotlight feature..

[ktronik]

My 'ugga' 6 Pack would be close to 1400lm.... 6 cree Q5's driven @ 1.2A each from the maxflex...

7 Q5 Fenix P3Ds:
1,505 lumens, $434.70

The boffins tell me you're closer to 1600lm K

Sweet... you know its bright when you take sunglasses for a night ride...

that's going take some doing... getting LED lights to equal output of the two HID lights I ride with.

HID storm and ARC HID ... one handlebar, other on helmet

I've also got an old Cateye stadium HID... it's much brighter than two mentioned. Cateye is a first gen with it's batteries close to dead. it was too bright to use for most rides. too easy to blind cars. runtime was never too great even when batteries was fresh.

now it's not a big deal getting 4+ hours from a smaller pack. 8+ hours on 8x 18650 pack
