finally, what a relief.  too bad they aren't tint labeled, and they coulda spared an extra bag instead of dumping the xp-g in w/ t6

Holy smokes what exactly are you building with 16XMLs? Any chance you can part with one for me to test out?

I am already visualizing the duct tape over your mouth.

9 are for 1 light Cool

i'll do a rough test and take the 9 best for that one

the rest will be used as singles, in projects I've already started, but obviously I won't be wrapping all that up any time soon so I could send one off.  I assume you mean to send it back?  Probably won't cost either of us any more than a stamp?  pm me an address...

tested all the xm-l w/ 1.4A and then 2.8A driver - simple ceiling bounce

now - all this is to be taken w/ a grain of salt - this setup was pretty crude (I may retest w/ a light box since they're all bare)...nonetheless...

the relative difference stayed pretty much the same at both currents but the higher current revealed a 1st 2nd and 3rd place (1 is noticeably brighter than all others)

for comparison (since it was the only one I had loose) I also tested the xm-l (claimed t6) from my xtar d06 (which will now receive that bright one!)

all led-dna emitters scored higher than the emitter from the xtar

2 of claimed U2 scored the same as the led-dna t6 - and those three were marginally brighter than the xtar (5%)

the rest (except the brightest) fell into 2 groups, roughly 10 and 15% brighter than the xtar.  the brightest measured 20% higher.

NOTE: the relative low score of the xtar emitter could VERY well be from my horrid abuse of the light and emitter...but it still validates the others (to some degree...maybe only to me lol)

i don't think I can assess tint until I get them in a light...

I bought a couple of 16mm T6 in separate orders, both arrived within a reasonable time frame (2-3wks I think?) and I finally got round to building one into a bike light for a friend. I don't have a single XM-L@3A light to compare it to (only a 2x XM-L@3A and 2x XM-L@1.5A), but it's about as bright as I'd expect with a nice cool white tint. No funky stuff at low currents either, even at the "oh, so that's what the die looks like when it's on" low of the KD V2 driver Smile

The other one will get built into an all-in-one torch/ bike light over the next month or so, so we'll see how that one works out. I have to say though that 20mm stars are nicer to work with if you have the space!
