For Europe just go to DEV-Pein.de
Nice guys with reasonable prices.

p.s. if you go for this type order the extra O-ring which is not included standard (+ €0,50)
Re: Aspheric mag SST50
The H6Flex was pretty easy to mount, I glued (DX fujik) the thermal pad to the back. Than I glued a copper distance holder 5mm thick with holes cut out for the wires to the thermal pad and that was glued to the led's heatsink.
Pretty deep, I don't have it on hand now...
Re: Aspheric mag SST50
If I read it correct (English is not my mother language) it says "Over 1,250 lumens from a single chip".
And than taking a look at the curve it is about 280% for 5,0A for the 500 to 600 lumen bin that would be between 1400 and 1680 lumen. :shrug:
+1 :bow: for making...
Re: Aspheric mag SST50
Yes I am over driving it (a bit) according the data sheet it is rated between 500 and 600 lumen @ 1,75A.
If you take a look at page 9 of the datasheet you can see that the graph has a straight line and the "current/lumen factor" is about 1,75.
This means that for 6.7A...
Re: Aspheric mag SST50
It gets hot but a couple of minutes is no problem, and with the H6Flex you have got the posiblity to dim and a temperature protection.
I am no expert on this measurements, in our company (KEMA) we have got a special department for automotive lightning testing.
These...
Nothing really special, but fun :D
3D maglite
Custom heatsink
4x C-size Li-ion
Taskled H6Flex driver
Top bin SST50 led
Cheap a$$ DX aspheric
Today I did some (calibrated) measurements and measured the following:
67lux @ 25 meters distance, I have no idea how to calculate this to a 1 meter...
I e-mailed with the guys from batteryspace about the shipping.
On my own risk they would also ship through USPS, thats a lot cheaper than UPS :D
Great service!!

As the title says I want to buy a protection PCB for a 4S Li-Ion pack with balancing function.
Like this: Batteryspace
The only problem with batteryspace is I dont want to pay $55,- of shipping for a $15,- PCB:rant::banghead:
So if someone knows a better adres please let me know.
Greetz Johan
Sweet, I have been waiting for this one!
I will need at least 4 of these (I asume you don´t take reservations:candle:).
If you like I can do some extensive efficiency measurements with all calibrated meters ofcourse.
