Thanks, frisco

[frisco]

Sorry if this has been mentioned before..... do we get batteries here? Or do we order them from AW?

[FlashMike]

I'm afraid I need to drop out. No issue with the light, just can't budget for another custom right now. Good luck - I look forward to reading of your progress.

[DFiorentino]

Confirming my second unit #141:

=== Aluminum 6061-T6 (Nickel Electroless plating) ===
Draco (complete light)
- Premium S@O@ LuxI emitter
- Constant Current Regulation (60mA / 350mA)

Prefered serial number: #5
Back-up serial number: #100
Back-up, back-up serial number: anything else

-DF

[Roger11]

Serial number 104 once again confirming Aluminum, Constant Current Regulation (Hi/Lo), lanyard, Lux III.

I am really hoping at the prices that this includes batteries also....???

[milkyspit]

Confirming ALUMINUM version with TURBO head (does the regular head come with it as well, or is it an either/or thing?).

As for the circuit: I get a bit picky about having smooth switching. If the constant current dual stage will be nice and smooth... no flicker, no dented batteries, etc... then it's for me! Otherwise I'll go with the uPIC.

PLEASE... SERIAL #097 if it's still available!

[Aaron1100us]

Yeah, I'm going to have to drop out too. Way too much $ for me right now. I was #38. Thanks. Was hoping for under $100

[CroMAGnet]

Time's up! Serial Number confirmation is over and I'm adjusting the list right now.

Most will get their numbers but many are asking to be moved to the same lower numbers and I need to give priority to the lowest original number cofirmers.

BBIAF

[pcmike]

Yes! No one asked for #006!! Puh puh please CroMAGnet, don't let me down! I'm going to get some gas, I'm gonna check this right when I get home. Can't wait to see the final list.

[CroMAGnet]

Regentag Ti light serial numbers only go up to 50. So I put your two TiCN lights in #11 and #12 but if you want a gold TiN I can get you into #6. Please post your choice
dbedit I have you in #4 TiN, Let me know if you meant TiCN
mohr #20 Aluminum is taken but you can try to PM JimH and ask if he would trade with you, ask him to let me know. - Please let me know what I can get for you from the available numbers.
Roger11 You got #11
Bern I got you on my list at #14 and will post it on the next update. (#14 TiCN w/Turbo) Welcome to CPF, hope you stay a while
pcmike Yeehaw! U got #6!!


This was tricky but after a couple more hours I hope I didn't miss anyone who confirmed and I hope you all got the numbers you wanted

We still have about 15 more that need to confirm.



It's Late now, must sleep

[erinO919]

Sorry, I'm out, too.

[marcspar]

I just got back from three days away from the net. Can I still get my unit?

I was number 46 - aluminum.

Thanks,

Marc

[GJW]

Please move me from #9 AL to #42 AL.
Thanks

[flashlight]

Ti/Tin #2 should still be available as I'm not taking it unless there's another CPFer with the username 'Flashlight'.

[trivergata]

Sorry - I had a last minute trip for work to a place they've never even heard of the net, and missed my spot!

Sorry for the hastle, Cro

Josh

[CroMAGnet]

Josh, You still have a spot, just not that serial number. I can give you #9 Alu #2 TiN or #15 TiCN

GJW: Moved
Flashlight: removed TiN
Erin0919: removed
Marcspar: Gotcha on #46 Alum, unless you want a TiCN or TiN

[marcspar]

Tony, thank you! Number 46 (aluminum) it is......

not sure if this belongs in the sales thread, please move if inappropriate.
also, if in posting this i have violated some protocol or unwritten rule, modamag, please accept my apology in advance.

i was trying to figure out runtimes for different combinations of the S bin and U bin LEDs, with the constant current and PWM drivers.

i've come to the conclusion that, at these drive levels, you will get pretty much the same runtime regardless of whether you choose the SX0H or the U_0J LED. so it's probably best to make your LED choice based on the driver you prefer...

as modamag said, choose the U_0J if you get the uPIC so it can handle the burst
if you are concerned about tint shift from underdriving the U_0J with the constant current driver, just go with the SX0H

EDIT 7/3/2006
- incorporated input from chimo and goldserve
- added 2nd chart to cover AAA battery
- added bottom end of each input level from uPIC driver

EDIT 7/5/2006
- added additional battery types suggested by blahblahblah (thanks)
- combined all battery types into a single table



NOTES:

* per chimo's suggestion, used lumileds datasheets to estimate Vf at different inputs. lumileds data is +/- 0.06 V
* SX0H max Vf is 3.99
* 90% efficiency assumption borrowed from modamag
* shows both top and bottom end of the range given by modamag for each drive level, as well as drive levels suggested by others
* maximum input from uPIC driver in burst mode reduced to 700 mA per goldserve
* at the end of the runtime, the battery would be completely exhausted if there were no protection

thank you chimo and goldserve for feedback. please let me know if there are other factors that need to be taken into account.

these are mathematical estimates only, and the real-world results will be different depending on a number of other factors. this is just ballpark.

here are the posts (mostly from modamag and cromagnet) from which i picked up the relevant information, including the basic formulas:

I'm going to have to back out. Sorry. Looks like a seriously sweet light, and I'll probably regret this.

[MorpheusT1]

Sorry,


You can remove me from the list.

The burst current will most likely be around 700ma or less if people want. With such a small battery, I'm thinking 450ma should be the max. What does everyone think? Li-ion safety or mad brightness in a small package?

Kevin, you should probably set these at 2C of the intended battery packs. If the 10440 batt tubes are used then ~600mA. For the 10280's then 450mA makes more sense. I would recommend the lower figure.

[chimo]

i've never done this type of computation before, so i have no idea if these results are correct. please let me know if i've not included something significant.

Here's a fairly significant issue you should factor in. The Vf of the LED is not static - it changes with the amount of current passing through it. The Vf range quoted in the bin is for a 700mA drive current for the LuxIII and 350mA for the LuxI. The V/I curve is not linear (especially in this range), but you could probably count on at least a 0.4V drop for a LuxI and a 0.7V drop for the LuxIII going down to 60mA from the rated drive current.

Mad brightness wont mean much if the lights explode or ruin batteries. Please play it safe.

[Roboholic]

Will batteries be supplied or do I need to order some now?
Will the nano charger that came with AW aaa & charger pack work with a spacer?
I know I am putting the cart before the horse here but just want to be prepared.

What sort of time-frame are we looking at???
Time-line projects would be nice...

[liqht]

thank you goldserve and chimo for additional info...see updated runtime estimates above
