another 12 x led eye burner?

Originally posted on mtbr...but I figured peps here would like a peak. Still waiting for the slow china boat. Should have got in on the R2's a seller on this site had...

Almost done building this 12 x Q5 light. A Maxflex will be running two strings of 6 Q5's in parallel...so 600ma per led. Here are some pics...

The driver and status light mounted...

Trimming the lens to fit...

Inside the body...

Assembled...

Font view, lens and leds loosely inserted for show...

Side view...

On the bike shots...

Waiting for the remaining leds to come in. I'll post some beam shots when everything is wired up.

Let us know the rest of the process... Look great...

oops. posted on mtbr, but forgot to update here

I suck at taking beam shots. I only have a point and shoot. Set it at +1 exposure...

Here's a reference shot:

Full power:

Turned off:

The beam is still very much a spot, w/ side spill. I think I'll like it since I can point it way down the trail and still have the side spill for close up. I can always put some shims between the light heads and the main body to point them away from each other to get a wider beam...but I'll wait on that till I get a test ride.

Got a test ride in w/ the light. WoW

I had her on low most of the time...it was enough...even for the fast downs. When I put her on high, I think I blinded some rabbits on the trail and almost ran one over. I didn't measure the current, but the maxflex at high is 600ma per led and I have the "low" set at UIB2 Duomode L3; I'd guess it's at 300-400ma.

Reference:

"Low"

High

"cool" thing was, on low, the light didn't even get warm

looks very bright... Good stuff. L3 on the maxflex is only going to be 150ma per led. The curent basicaly halves each level down apart from the bottom level which is a fixed 40ma I think (so only 20ma for your 6s2p setup.) Basicaly drop one level you double your runtime.

Personaly I am realy looking forward to doing somting that should have this sort of output in a lot smaller size with 3 * mc-e.

Also looking fowarad to the mc-e's. However, the smaller size also means less surface area for cooling. Should be interesting.

Gorgeous job, amazing results...:twothumbs

Yeeeeee Hawwwwww! Verrrrry nice. The more light the better. I have just got into mtn. bikng and have been trying some ideas, I like this idea! (Snoqualmie tunnel, 2.3 miles and DARK)
