World’s Brightest LED Bike Lights 2010 I ride a bike to work. I ride a bike home at night on an unlit country road. I use a 5 watt LED bike light which gives a feeble spot of light ahead of my bike. So, I think to myself “what if I had a brighter light on my bike” I think to myself “what if I had a really, really bright light on my bike” Hey, I’m Tesladownunder, “what if I had the world’s brightest light on my bike” What would it take? I have experience with a huge 100W LED that is brighter than a cars headlights. But that is simple to do and I have already done that almost as a joke. But what extreme can I take this to? Lets make a real project of this and give it a real budget – say $1000 (later blown out to $8,000). So….here it is, ladies and gentlemen; welcome to the Worlds Brightest LED Bike Lights. How bright? 100,000 lumens. Remember that figure. Gallery

 OK. Step one. Take a ladies bike with front tray and rear carrier. Add a big round thing in the front and some tacked on stuff and you can get some idea of where this is going.  So here it is.

       Lighting a lighthouse! Here is ONE 100 W 6000 lumen LED focussed to a 5 degree beam. I will be using 15 of these in the front of the bike. Check out my 100W LED page. The Bunbury lighthouse is on but you cant see it’s beams easily in the photo from this angle. The 100W LED runs on three 1.3 AH, 12 V SLA batteries attached to the LED which is resting on on the wooden fence here. It is fan cooled and runs around 3 A 34 V via a 0.4 ohm resistor, if I recall. This is 6000 lumens – remember the 100,000 lumen total figure.

The World’s brightest flashlight shown above lighting a lighthouse with different colours. The last photo is with lights on full with much shorter exposure. This uses 15 of the 100 W LEDs.

First light for the rear lights (above). These are separate red, blue and green and are mostly decorative at a “mere” 300 W. Shown here with blue (left), red plus blue (center) and red, blue and green (right). Specifications Front lights: 15 x 100 W LEDs (12 white, 1 red, 1 blue 1 green: all approx 6000 lumens) 1500 W total 90,000 lumens Beam 5 degrees Rear lights: 3 x 100W LEDs (1 red, 1 blue 1 green) 300 W total 18,000 lumens Beam 20 degrees Total: 18 x 100 W LEDs (12 white, 2 red, 2 blue 2 green) 1800 W total 108,000 lumens (range 82,000 – 115,000) ie approx 100,000 lumens total Power: 3 x 12 V deep cycle 33 AH batteries Run time: est. 10 mins at 60 A 33 V LED data from Led-world2007 are limited and to my mind insufficient and at variance with other similar LEDs. The lumen question marks in the tables below are for the quoted lumens from similar LEDsfrom a different manufacturer which might be closer to the true values.

Concept In designing this bike at this time I am taking advantage of two things. Firstly, my experience with a single 100W LED last year (when they cost $500) and secondly that pricing of the 100 W LEDs have dropped to around US$100 which makes a multi – LED project feasible. So with some expense I can make a leading edge project with massive light output that was not possible only a few months ago.  Some of my original concepts are shown above. Things have evolved a bit since. Note that for static displays or media it will work better if it is not just a “one trick pony” but has other aspects of interest. So my primary goal is massive light output but in addition I want it to be a light that I can strobe, pulsate, dim, sync to music, or colourise to any colour at reduced power. This is not meant to go on the road any more than a monster truck or an F1 racer is meant to go on the road. They are the expressions of the strongest and fastest extreme versions of the 4 wheel “car”. But we still enjoy watching them in their place. These bike lights should never be shone at oncoming traffic. Nor the brake lights either. This is a display bike. I will have a very low power setting of a few watts that will suffice for road use and maybe a standard bike light set for emergencies. So, this is definitely NOT a mountain bike setup. Apart from TV and print media, I envisage this being used in static displays, at bike shops and shows. I won’t get many miles on the clock. It has 3 internal gears but is nothing like a proper bike to ride.HID’s/Xenons are a bit more efficient than the best LEDs. They are also more compact and are much closer to a point source and can be focused tightly. So for that tight beam they would be great. However, I don’t have any special expertise with “glass” but do with 100 W LEDs so that seemed the natural way to go. “Ohh really …. someone else claiming the biggest and best”. Well yes, but this here is the data. My bike has 100,000 lumens. Compare:
