Hi guys,

i have been reading now quite a while in this forum, and now i want to make a contribution to the DIY community:

I designed a round PCB with four MC-Es M-Bin on it with 55mm diameter, so you can easily make small round housings on the lathe for high-performance lights.
There where some requests in the IBC-forum from Germany (where i am more active) so i thought here might be some guys who are interessted (also i know most of you prefer milling your housings)...

The PCB is designed to use BOOM reflectors or the LM1 optics.
With this configuration you can easily reach the (real) 2000 lumen mark (measured by a guy from the IBC-forum in a "ullbrich sphere").

This is the link to the thread at the IBC-forum, but i don't know if you can see all the pictures without being signed in there:
http://www.mtb-news.de/forum/showthread.php?t=430057

I orderes some of these PCBs, so if anyone is interessted, please write me a PM.

Cheers,
Robert

(and sorry for my bad english)

EDIT:
hmm, it didn't really work out with the pictures...
The beamshots were taken with the "official setting" from the IBC-forum (4f/ISO200/2sec)
The markers are at 5, 20, 50 and 80 meters, the ground was a little bit wet
1. 2BOOMs spot, 2BOOMs medium
2. 2BOOMs spot, 2LM1 D

On the pictures each of the four MC-Es (wired in series, if not noticed) is powered with app. 850mA.
The "lamp" so far looks like this ;)

4000+ lumen in the house!!!
YEAH (but it should be dry ;) )

Puhhhh, this time it worked out :D

In my opinion, the LM1-combinations give the best light. I prefer driving with them.
They have a good throw and there is no sharp bright/dark line like with the BOOMs.
The BOOMs are good, if you have a helmet-light with much throw for the distance and sharp corners...

Hi guys,

i just wanted to tell you that the LEDs arrived :)

I am still waiting for the lenses/reflectors.

I ordered BOOM-S and LM1-D
The BOOMS for very much flood,
the LM1-D for more throw.

If you want some, please write me a PN :)

Hi il2mb,

yes, the LM1-RS has a donut-hole, that's why i go with the LM1-D
There is no difference in throw, perhaps you could measure it, but you cannot see it.

Since it is German and not English it isn't strange you don't understand it.

Vielleicht möchten auch die Deutscher Englisch sprechen auf mtbr?
