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

3. 2 LM1 D, 2 LM1 RS
4. Layout of the PCB (little bit changed to the picture above)
5. Tesla for comparison... (candle in the wind )

That's some serious light! How are you powering the emitters, and what current level?

 

[rob1111]

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 )

I like the second beam shot the best. Are you sell those??

 

[rob1111]

@ biketuna:

Yes, i am going to sell the PCB with the emitters and optics/reflectors soon.
I already ordered some and will tell you in this thread when i am ready to send them...

 

[rob1111]

Sorry guys, there was a little mix up with the beamshots, i don't know how to insert images properly...
So this is the next try

two BOOM RS and two BOOM M

two BOOM S and two LM1 RS

two LM1 RS and two LM1 D

two LM1 RS and two LM1 M

 

[rob1111]

Puhhhh, this time it worked out

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...

Nice work. I'll be following this.

 

[rob1111]

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

Robert

Rob,


Does the LMl-RS produce any halo? And does the -D provide the same throw as the RS?

Thanks

 

[rob1111]

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.

how much $ ?

 

[brows141]

You have a PM!! Can you post a pic of what the finished product you are selling looks like?

 

[rob1111]

Here is a picture of the final PCB (with and without LEDs mounted)

 

[mtb_robs-x]

2000 lumen, now we getting there

good work, would like to see more,...

wie ist den das wetter in muenchen ?

Es ist ziemlich kalt

Wohne aber mittlerweile wegen der Arbeit am Chiemsee...
Und hier kann man bald die ersten Feierabendskitouren gehen.

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?
