Light Upgrade from stock bulbs

You've got that backwards...... Lower power draw = lower current = LESS strain on the rectifier.

hmm.. i'd always heard the rectifier has to burn off any unused power as heat...  if you're lowering the draw, you're increasing the amount it needs to burn off... /shrug

Well I'll let u guys know how it pains out so far nothing bad has happened. Will it I don't know, I'm not an electrical engineer/electrician/etc so i have no idea what this rectifier is u are referring to all I know is that the light works great for what I need, and if it blows up or catches in fire, lesson learned!!. I'd prefer the light to be thrown out a bit farther and provide a bit more lighted area. Also my distances I mentioned above are not accurate its just me making a comparison they may in fact put out a usable light beam to 100m, i just was stating there is a difference. 

The shorter led stack may work better for focusing, as the light source would more inline with reflector. I'll have to see what I can find or a shorter stack/lled array. Only issue i see is that there may nit be as many LED's to give off the light.

Well after some considerable use and taking the bike out on a back road at 11 at night, I am going to recommend you do not use these bulbs outside of an urban centre.  The distance the light is projected is phenomenal, but the usable viewing area is extremely and I mean extremely short. I was riding in the middle of the night on a backload with tree's around and I was only going 50kph and I was seriously white knuckling because you could not see more the 20m which is not that far ahead. 

They are great for urban just do not use them as a light for heading out on the back roads.  They are extremely bright but most of the light is lost/scattered and not focused.

I would not suggest bulbs from iJDMtoy.com. I purchased some of them for my car of bulbs of about 6 LEDs each. On most of them, at least one has burned out. They are also not very bright compared to other LED brands. Many people say they buy cheap LEDs that aren't very good. I would suggest going to ebay and searching "cree LED white 9006" (with your own bulb type and color). Cree is the brightest brand of LED I have ever seen, and you can only find companys on ebay from china that buy them in bulk and make bulbs. You will know its a cree when it has a projector/lens bulb onto the top of the bulb.

Because the headlight is in a reflector cup I would suggest buying a bulb that has the cree LED projector on the top as well as 4-8 SMD LEDs to light up the cup.

Good luck next time! Remember that all LEDs are not created equal.
