    Lupine SL AF

    Thanks for the images! Yes, the position of LEDs suggests there's no reflector, LEDs are in focal plane, and the aspherical lens is doing the rest of magic - shapes the light into proper beam pattern. (and the 6 peripheral LEDs are DRL then). The bottom row? I know mtb-news.de is a great...

    Lupine SL AF

    kj2, I'm curious how it's made optically-wise. Does it have a reflector inside? How many LEDs are there for low beam? How the reflector (if any) and LEDs are sitting there with respect to the front lens? Things like this. Do you know any forum threads with good photos of the insides, with...

    DIY-powering of modern LED car headlights

    Thank you! And I'll definitely keep in mind this note about Japanese lights.

    DIY-powering of modern LED car headlights

    Actually, I think your reply is almost as helpful as it can be! If it's super simple, I can safely buy one of them (I'll keep your PM-offer as a raincheck :) ). The only missing thing is generation of the model - for those that have more than 1 gen. Could you specify the gen? (if you had...

    DIY-powering of modern LED car headlights

    Thank you! Yes, I was aware of sensors, and even a camera. Ok, let me soften my expectations, let's assume I'll buy electronic control unit (ECU). Anybody knows any headlight that, when its ECU doesn't get any signals from its sensors (suppose there's no physical contact for sensor wires in...

    DIY-powering of modern LED car headlights

    Hello everyone! I want to experiment with modern auto LED headlights, in home environment, powering them from some DIY electronics. Nothing special, just to take wall beamshots for comparison with bike's. But really, in room's environment. I want these experiments to be cheap (because it's a...

    Busch&Muller Lumotec IQ-X headlight

    Strictly speaking, there are 4 more actually :), 2 for backside, and 2 for side visibility (thanks again to the walls of the elegant cylindrical housing). The main night "single" LED is actually made of two LED dies (last photo in post 37). Outbound uses a row of 5. That's what I meant. True...

    Busch&Muller Lumotec IQ-X headlight

    Thanks for the link, nice photos there. From the beamshots it looks like B&M sacrificed optical/technical superiority in favor of aesthetic looks. The near field, although well adjusted (IQ2 lens?), is very narrow — apparently due to cylindrical housing walls blocking the rays. If the housing...

    This guy has to be a flashaholic. Custom modded POV bike light for night riding

    Also, the cyclist image is clearly a montage: no rear wheel, and since background is visible, there must have been a "tail" from the front light (the ghostly appearance could be fine otherwise). And a PhD and IEEE editor is unlikely to do such DIY-ing. April 1st?

    repairing a Supernova Triple dynamo headlight

    ‘No, no! The adventures first,’ said the Gryphon in an impatient tone: ‘explanations take such a dreadful time.’ :) Is it the "E3 Triple"? The blinding one - for off-road? (I'm mainly interested in road - StVZO lighting)

    Philips LED bike light

    Hardwarely - no changes, nowhere. Weather - if you mean buttons hole cover - it's fully rain-proof. Charging - old. Weight, and center of gravity difference - small enough. AFAIR, it was tilting down when riding on bumps about same as the original. A piece of flat rubber glued on the handlebar...

    do people know about "We Test Lights"?

    Used to be interested a while ago.. Same useless shoot-out photos that fans make.. I understand, abundance of bike lights, and lack of time and, probably, knowledge, so their "method" is simplistic, ok. But a company!? Why no beam patterns?? I, a hobbyist(!) did it, essentially without any...

    Philips LED bike light

    Probably. I don't really care about runtime. (what I do care about - unlike other people, is SR's near field.. really hate it) Yes, parallel. I put my charge connector where the original was (USB) - at the back. Any Li-Ion charger will do the job (I use one from a bike light, 1A), after you...

    Cantor, DIY: oncomers-friendly, 1S Li-Ion, rich-control firmware, beam 3D simulations

    There was some (little really) interest in my octave scripts a long time ago.. I wrote instructions how-to get beamshots simulation images fast (the proper beamshot visualization): Taking "Cantor" beamshots. It's not quite "for dummies", but I tried to make it. Also I re-structured main page...

    Philips LED bike light

    My SR80 modification. Back to the blinding artifacts - I recently installed the wall (black, between the halves): (hi-res) Color-zoomed-in (to better see artifacts) original vs. wall: Main pattern is almost same, became about 2.6% narrower (I expected worse): (hi-res) (hi-res) (you can't...
