question about l.e.d lights & requirements

[Brian VT]

2 of my buddies replaced their stock (KTM) headlight with a Rigid Dually.
I've ridden the bikes and it's bright enough that even helps in the daytime woods ! I can get more details if needed.

My brother cut an extra number plate for two 900 lumen LED driving lights like the VisionX on his Husky. Very bright and still fits like a number plate, so low profile. You can still run numbers on it if you want. It would be easy to do this for a GG with all components on the back of the plate and a simple connector to the assembly.

jgas,

2K-2 is 35-40W AC output max, no matter how you slice it, and that does not mean a 40W DC output. Considering the losses, you can forget about HIDs. LEDs are the only real choice when trying to squeeze useful light out of this ignition stator. A couple of 10W high output LEDS is a realistic maximum for a reliable system. LEDS are so efficient though you could run a couple more on your helmet as Paul suggests for hours on a very small battery pack. No need for large heavy batteries anymore. Plus, LEDs are virtually bulletproof, unlike the small HIDs which fail on a regular basis.

Glenn,
Do you know what output the 2k3 has ?
I am looking at purchasing the Baja designs squadron setup.
Thanks Mark

I ended up buying 2 magicshine 808 led lights & put one on the bars with the 30? lense and the other on my helmet. I just used them last night for a couple of hours and I love them. They are amazing for such a small light. A guy on my 24 hr team bought a cyclopse led adventure light for twice as much as my $89.00 magicshine & it didn't do any better than mine. I might try running one off of the bike later but the batteries are so small & last so long I don't see the need. Check out actionledlights.com

I think 2K-3 is 75W on one winding(yellow) and 15W on the other(white) but they are out of phase and cannot be connected together. You could probably use two phases of a three phase rect/reg or make your own if you need all of it.

Mark,

I looked at the Baja Designs Squadron LEDs. Four LEDs for $300 is overpriced. I just had in my hand yesterday, a copy of the VisionX I used to run. Looked exactly the same except it did not have the waterproof connector system. Alloy housing that can be linked together in a block or bar, which is what BD has done. Same emitter. My neighbor bought a pair for his BMW for $53 on ebay. BD is making a lot of $$ on this one.

These emitters/controller run constant 10W power output from a 9 to 30 volt input. You will have no problem running four on a 2K-3 DC conversion, even six should be good. Should be easy to set them up in a bar configuration that mounts to the triple clamps for easy R&R.

Thanks Glenn,
So what you are saying is that they are identical in input and output ( bar the waterproofing)?
Do you know if they can be switched ( i.e high low beam?).
Anything specific to look out for or beware of if buying off of fleabay?
Cheers Mark

Yes they appear the same. The originals came from South Korea, the emitter is made there also. That emitter/controller is the same one used in all the high output single emitter LEDs. 10W constant input approx 900 Lumens. The lenses vary, spot to flood. The ones off ebay l saw looked pretty good, no connector but same alloy enclosure and stainless mount brackets. Not sure if they are just cheaper Korean units or Chineese clones. In any case its a great way to get a lot of light on a bike. The small HIDs are a nightmare as far as reliability.

Mine could not be switched but the newer VisionX can. Not sure about these. So little draw why bother? Its not like a headlight that switches beam pattern, just intensity.

I'll try and find out exactly where he got them, may get some myself. I think a row of them on the upper triple over the number plate would be slick, no special plastic/headlight shell mods needed. Just a bracket mounted under the bar mounts. Could also mount the rect/reg and a cap or small battery, with a simple AC connector to it from the stator like your OEM headlight. The lights actually link together, so a bolt on each end light is fine.

LED lights are typically full ouput only. To get a reduced output, you can use an external PWM control to vary the brightness. I use this unit:

Thanks guys.
The reason for hi and lo beam switching option is because it is a rule in the 24hr race that I am planning on doing if I get the lights sorted.
Thanks Mark

That will likely not work with the lights I am talking about as they have their own integrated controller, and have the same output for a large input voltage range. That controller linked to is suited for basic LEDs or halogen lamps.
