Luxeon Tri Rebel usage question

[mariom]

Hello There,

First i want to excuse my Bad english again.

I've ordered a Luxeon tri rebel wich i want to use in my Saber.

One blue/blue/white
And one white/white/blue.

Wich is better for a bright light blue.

Build in is a Nano Biscotte V3 with 3.7 Volts Set up.

Can i use all three LEDs wired parallel? Of course with the right resistors.
I don't want to use one for Flash ob Clash. The Blade flickering from the NB v3 is good enough for me.

Best regards
Mario

I calculated a Little bit.
Is the following ok when i'm wiring parallel.

@1000mA

The two Blues need a 0,22 ohm 5 watt resistor (i have them at home)
The white need a 0,47 ohm resistor. Also in 5 Watts
But thats are 3 amp and the NB V3 has 2 Amp direct drive

Or should i go with 700mA
3x 700mA = 2100ma
Blue with 0,47 ohm = 3,4 volts
White with 1 ohm = 3,0 volts
Is this better

Has Nobody an answer for me?

I haven't read the new manual for the NBv3. Can the main led pad handle more than 2Amps? If I remember correctly, that was the limit on the NBv2. Could be wrong though.

2A is the published max per pad for the board.

[mariom]

Then i should go with 700ma per LED.

Blues with 0,47 ohm i will get round about 650-675 mA
White with 1 ohm will also be 650-675mA

So all three will be 2000mA

You most likely would be better off running one Blue at the full 1A and running the White at around 700 mA to get a light Blue.

Reverse it and you have a nice silver or icy blue.

And which of those were the "bright light blue" the OP asked for again??

[FenixFire]

Icy Blue vs. Light Blue...he never gave a pantone color he was trying to hit. 'Light" blue is very vague. Maybe it is just the designer in me speaking but bright light blue could refer to 1000's of shades of blue. I was just giving him an example for dialing in the color.
