Custom TRI CREE Help

[jt_trouble]

Is it possible to run to run a Custom Tri Cree with a R/B/W dies, off of a NB2 with PEX using a 3.7V Li Ion battery?

Can the R & B be run in parallel and the W on the FOC circuit?

Which resistor will I need for the RED and which resistor will I need for the Blue?

Blue I was going to use a .5 Ohm 3W Resistor.

Red .. no idea. My calculations using the directions in the NB manual don't match up with anything on the TCSS lists. Or am I'm just doing it wrong. (??)

I'm trying to achieve a purple blade. Please help. Thank you!

Don't run them in parallel, run them separately for the proper resistor value. What value are you getting for the Red resistor? It's Ohm's Law, also read the owners manual, specifically the section "Advanced wiring using Flash on Clash and Tri-rebel "

Yes, it's "possible". The resistors you would need would depend on the shade of "purple" you are aiming for. I personally would runtime Blue the 1A and then resistor the Red to help get the shade you want. You would have to experiment.

I don't know why you would need a 3W resistor for the Blue though. Offhand , I would guess that you are doing the calculations wrong. I left a tutorial in the wiring section that may help you out.

Just a warning, I suck at math. lol

Following FJK's Down and Dirty Tutorial ..... Info from TCSS pages

Blue Cree Part# XPEBBL-L1-0000-00301
45.7 Minimum Luminous Flux @ 350mA
Forward Voltage @1000mA = 3.47v

R = (3.7 - 3.4)/1 = .3/1 = .3 Ohm?
W = .3 x (1) = .3 x 1 = .3 W

Rounded up ... .47ohm .5w resistor


Red Cree Part# XPEBRD-L1-0000-00901
80.6 Minimum Luminous Flux @ 350mA
Forward Voltage @1000mA = 2.59v

R = (3.7 - 2.59)/1 = 1.11/1 = 1.11 Ohm
W = 1.11 x (1) = 1.11 x 1 = 1.11W

1.2Ohm 3W??? Sorry just guessing.



White Cree Part# XPEBWT-L1-0000-00F51
266 Minimum Luminous Flux @ 1000mA
Forward Voltage @1000mA = 3.15v

I'll figure this one out once I find out how bad I messed up my calculations for the first two :P

You're calculations are correct sir!

[jt_trouble]

You're calculations are correct sir!

Well that's good, here I was racking my noggin thinking my calculator was against me lol

I personally would runtime Blue the 1A

Does that mean "no resistor"? Originally that was what I thought (more like guessed) that it wouldn't need one.

Would you also run the White FOC die without one as well?

[Forgetful Jedi Knight]

No, I NEVER recommend running a main LED without a resistor. I'm just saying you will need to run the Blue at it's full potential, and the Red at less than it's "full potential".

Good.

I'm just going for alive and kicking, so what shade it comes out is something I can tinker with later.

Here is my FOC math ... please advise.

White Cree Part# XPEBWT-L1-0000-00F51
266 Minimum Luminous Flux @ 1000mA
Forward Voltage @1000mA = 3.15v

R = (3.7 - 3.15)/1 = .55/1 = .55 Ohm
W = .55/1 = .55 x 1 = .55 W

Rounded up the closest I get is 1 Ohm 2 Watt resistor.

Yes, the 1ohm 2W will work fine.

What would be the best way to wire these up?

A link to a diagram would suffice, or post it here.

I got this pic off of a facebook group page. I plan on adding an illuminated switch as well.

Any other ideas or best way?
