I have three LED's plus optics from a night lightening I-Blaast if anyones interested for a DIY project. Think they are Cree Q5's (240 Lumens each @ 1000ma). Upgraded mine to the new Cree R2's.

How about $40? They are worth about $75 Australian including optics and star mount at Cutter.
Have had about 20 hours use max.

Hmmm, I wonder if two of the 20mm triple R2s could be squeezed into a nightlightning head....
1100lm lumens anyone?

At a guess yes. Heat might be an issue with them though.

Nah run them in parallel 600mA each.

At 750mA they get hot quick if you stop for a minute or two. Would hate to think what would happen with near twice the output :crazy:

When I stop my lights do too!

The nightlightning heads run at 1200mA so just split that over the two boards. 20% more light, less heat, 10% longer runtime.

How much better are the iBlaast II's over the original Iblaaaast!? $70 better?
I promised myself I would get some night riding lights before the winter this year.

Yep - noticeably better. I upgraded mine last week.

Has anybody seen or done anything similar to this project?

http://www.instructables.com/id/Ultimate-Night-Vision-Headlamp---500%2b-lumens-with-/

The cyan light seems to be a plausible alternative to the more and more lumens coming out of the Cree's. I have priced the major components to less than $50US including shipping. I am sure there are better ways to mount them though. The gluing straight to a heat sink and covering in silicon seems a bit crude.

Stuff looks funny under funny lights, even very bright funny lights.
White light is good because grass looks green, mud looks brown, blood looks red when you fall off etc.

A yes good point. I hadn't thought about that. I had pretty much well discounted that design already anyway because i had figure out that the 500+ lumen he was talking about was with the 2.5X for the eye thing added. The real lumens were just over 200 ish.

Anyway ... I have come up with a new design. I am going to build something similar to plummet on page 47 but using Cree MC-E's 430 Lumen Cool white. The question is though, I really just want to run 1 mode (around the 750 Ma) so just an on off switch is fine by me. Do I need the hipflex and hipcc or can I used something else?

I have no idea what the 500lm/8W is about, each led was rate 45lm at 1W.

Kai have cheap 2.8A boards. 1 for each MC-E wired parallel.

This is going to give you well over 1000lm, so you might want a multi mode driver to cut it back (I found 200 plenty for climbing).

Me, I'd go for the taskled stuff, cause its good quality and nice to ride with if you need multi modes. Plus the kai stuff is often crap.
