Took a while in the manual mode to accurately reproduce what I was seeing from my eyes. Yes it is that freaking bright. I used 4 x 3.6-9v @ 800ma (80% full power so each LED is getting 80% full power and not 80% divide 4) wired in parallel to achieve this and used a 6xAA battery holder which I will note is pushing the batteries hard but it's mega bright and the 6xAA weight/size/space penalty is worth it as downhill burners or when I'm riding fast in a dark area for a moment.

Edit: LEDs being used are SSC P4 U-bin (bin is like a 'grade/selection'. Think of it like diamonds and thier grading) which when I got them at DX back then it was ~$7.50 USD/ea unit. Now a days it's getting closer to being $5/ea which is good for newbies to try.

The photo shows a 4xLED unit and also a 2xLED unit (2xLED is also SSC P4 U-bin) both on high.

The photo below shows only 4xLED's on.



You may not notice the extra brightness but in person yo will see it about 20% brighter which is good when you need extra lighting.

This is the control photo so people know what I was dealing with before the ligths are one and so they can guage for themselves.



Camera was tripod mounted so the photo is the same in each shot give or take a possilbe 5% bump on the tripod shifting not that is makes any difference.
