Voltage bin code marked on LED?

Hello,

We are using LEDs in parallel in our product, so we need the LEDs to be from the same voltage bin.
We are using the Osram Power TOPLED "LA E67F"

Is the voltage bin code marked onto the actual LED itself?, or is the bin code only on the reel or tape in which the LED is delivered?

Power TOPLED datasheet:
http://catalog.osram-os.com/catalogue/catalogue.do?favOid=0000000d0002d78e00780023&act=showBookmark

Do you know of any LED brands which have the voltage bin code marked onto the actual LED package?

We need it to be marked on the package so that we can check that the PCB assemblers are using LEDs from the same voltage bin.

My guess is that it's not marked on the device. (although you could confirm that)

Are all the parallel LEDs on a single board? If so, all you need to do is ensure that all LEDs on a given board are from the same reel. If you're having them assembled, that will be taken care of by the simple technique of only having a single reel of them on the pick and place machine. Once that reel runs out, and partially populated board is likely to be a reject.
