    The smallest but very bright light for helmet/bike

    see the updated specs on the smallest (just 12 grams) 240 lumens light available on the market:

    nope, just a head integrated with regulator circuit. It can be connected to any battery which has voltage in range 4-15V. This is a laboratory sample, so it's not cheap. We're going to release soon the same size head rated to emitt 900 lumens.

    I would probably be in for a 900 lumen unit, but for 85 bucks for just a 240 lumen light head I would probably consider other options personally. I have a 14.8 lithium battery I'd love to use with a light system.. if you sold one that had trail tech ends and retailed for around 120 bucks or so I'd probably buy.

    I'm all for light lightheads for the helmet but 240 lumens simply isn't enough. It would make a great hiking/camping light though.

    What about to just double it, like this:


    Here's just SINGLE light in action:

    if you switch them both - you'll get the power doubled.

    I have to admit there is something about these little lights that I like. Even if you already have a primary bar light a set of these mounted on the bars ( as shown ) could be hooked up to provide additional side visibility ( as they can be pointed where you want.. ). Used with a 2 cell 18650 series combo and a remote on/off switch, you could have on-demand wide turn lighting...this could work. Not sure it would be worth $ 170 plus shipping to find out though.
    Once again, ( the second time in a couple days ) I have to question the beam shot. Output looks more like 500lm, you sure this isn't a photo with both lights on? A set of these with XP-G's and I might have to reconsider ( if kept under $200 ).

    first of all thanks for comments. Regarding the beamshot posted, yes, it a single light in action (according the testing rules). Compare it with other commercial and DIY lights at

    http://fonarevka.lux-rc.com/ (Road & Road2 series where I participated)

    it will give you much better understanding of the L30 light spill and performance.

    Most people wouldn't call 240 lumens "very bright". ;-)

    Will there be an XP-G version in few weeks?

    ...Or how about a twin XP-G lighhead at 24g? ...now that would be nice!

    It depends on... I believe that 240lumens is maximum what possible to squeeze from a super-lightweight 12g unit. Simply because even if a new XP-G is used, it still must be able to dissipate 4W of heat. That's physics.

    A few weeks sounds very optimistic :-). The main problem with this light to provide an adequate cooling. Estimated heat power is 10W (triple XP-G). To keep the same size active cooling could be a solution. But I'm not sure that small fan is string enough to survive on a bike.

    Ah!...Yes, having a comparison makes a big difference. It was also interesting to see the TR-801 and the Magicshine in the light shootout. Thanks for that link. The beam shot of the TR-801 I found very impressive. I like your lights. They are nice looking. If I had $170 burning a hole in my pocket I would surely buy a couple of these, unfortunately ...I don't smell smoke yet.. Having a set of these would make taking tight turns a real blast.

    A couple questions about the light test....Do you know the camera settings for the test? If so, what were they? What optic were you using on your light for the test? What was the distance from the light to the first object in the road?

    When is the 900 going to be ready?
    $20 more for the bike mount seems a bit high.

    the production plan is:
    L31 - a smaller version of L30, single XP-G R5. Custom optics with glass lens. 345 Lumens. Lead time - 2 months (Jan 2010)
    L32 - a larger torch with boost topology based on 3xXP-G R5. Custom optics with glass lens. Should give ~1000 lumens (Jan 2010)
    L44 - high-power head, 4000 lumens with custom glass optics and variable light spill. (Feb 2010)

    I like your lights. They seem well thought out and practical, and heatsinking seems to handled well. I was waiting for you to say something like this. More details when you can.

    $85 for "900" lumens (with li-ion battery, charger, & lighthead) is already here... Magicshine.

    Sorry to self-promote, really. I wavered when I hit "Submit Reply"...

    I really do like the looks of the unit described here. When did Russia get in the electronics game?

    Good on you for giving it a go, but I having built many light myself, I don't think there is enough surface area to cool the light when on high...if you have it @ 900lm...

    how long do you get before the thermal reg trip in still air?? on the 240lm unit??

    The L30 torch has been amended. Now it comes with a high quality super soft thermal resistant silicone cord instead of cheesy twisted wires in the past. The new cord is rated to sustain temperatures in range -50C to +200C. A few fresh pictures:

    it's rather a DIY now, we offer you to devise a power supply for it
    An "off-the-shell" is in close plans.
    The light comes with integrated regulator (DC 3.8-12V) and thermal control circuit.

    This brightness level is simply not realistic with a 240 lumen light.

    The telltale sign is the orange sky. The photo brightness is pumped up to the point that the dark sky becomes lit up.

    I'm just commenting on the photo though. The light itself looks awesome!!

    this photo is taken from the test at http://fonarevka.lux-rc.com. See it in "Road2" series. This color of the sky is normal for Moscow, - the same color on all photos. The brightness of the spot depends on camera settings. All photos are taken using the same settings, no cheating. Of cause L30 is not the brightest light on the market, but it's on sure the smallest one

    Yep, you are right about that as I just checked it as well. I also noticed the light-colored sky. However if you follow the link he gave the torch he shows is compared to other known light sources that gives a better point of reference. None the less, I don't think the camera settings are at the same standard as that of MTBreview.

    some fresh pics from the lab.
    I have started designing my own optics as a replacement for standard 20mm luxeon/fraen collimator:



    The main idea of this small unit to use silver mirror as a reflector and mineral glass lens to adjust the light spill in a wide range. The adjustment ring lets smoothly move between very narrow and wide angles.

    As an example how it looks together with L30 micro-light:

    The light looks very interesting, I like it! The fit and finish look great and the weight is great.2 things that are a must for most poeple here. The first would be that it needs to be brighter. Sounds like you are working on that. A single XP-G (R5 bin) run at 1 amp would be just sufficient. Second would be a low setting. Do you have any provision for a light with high and low modes? I think if you could figure that out, this would be an outstanding light. And yes, the extra $20.00 for the bike mount is a little steep.

    Good luck!

    Hard to believe that it is so light! I worked pretty hard to get the weight out of this light and still have enough fin area for cooling. As mounted on the helmet it is 27 grams and in the pic with the penny for size reference it is 20 grams. It also has no driver in the head (it is mounted with the battery).

    But that is besides Francis' valid point about exposure and what the sky reveals about it.

    If we knew the f-stop and exposure time, one could use photoshop to adjust the exposure to compare to photos taken by Francis, or vice versa.

    Great job, colleague!
    The main idea is simple - to minimize thermal resistance between the LED heat-sink and the radiator i.e. metal body. We have a secret how to reach minimal resistance. We use special quite expensive PCB construction and DOW CORNING thermal-conductive compound. Of course this forces the body to get hot. But the heat dissipation increases proportionally to the thermal delta between the radiator surface and ambient air. Simply saying a more hot surface disspates more heat. Anyway the junction temperature can't reach critical 120C because the internal thermal protection circuit switches it off when the body reaches 80C. In practice the light never exceeds 60C outdoors, normally it's a bit warm.

    Interesting lights, I like the idea of what your doing. Im in the market for a new set for a race in January next year to replace my original AyUps.

    Will you be providing full kits? if so what will it include/ how expensives?

    hi, thanks for asking! :-)

    in fact I'm not going to change the light mount, it remains the same:


    and the same mount will be shared by all new XP-G lights (single die L31 and tripple shot L33).

    Regarding the power supply unit, yes, I have completed the alloy housing specs and sent them to the factory. The electronics and LiPo cells are already in hands. I anticipate to complete this project by March-April. The test samples shpuld be available in mid-Feb.




    I'm going to use these slick professional Lemo connectors:
