Stupid Cree/Luxeon Question

[Bark]

I only have experience with the Tri-Rebel, but for the single dies why does it seem to have four soldering pads instead of two?

[Forgetful Jedi Knight]

It gives the newbies a "second chance" pad.

Aw, how thoughtful of them. Thanks for the information.

[Jay-gon Jinn]

Actually those pads are there to make it easier to wire several leds in series.

Another silly question just for the Cree: I see four pads. Two are clearly labelled + and -. Two are not labelled and are in between, so for the picture above, which is it?

1. Positive pads on the top / Negative pads on the bottom?
2. Positive pads on the left / Negative pads on the right?

[Strydur]

Right side is negative and left side is positive. If you look closely you can see the T shape bridging them.

Funny, when I look dead-on, I can't see it, but when I look at my LCD monitor at an angle, I see the T-shape. I guess my monitor isn't dialed in well. Thanks for the information!

Nah, that's normal behavior for LCD monitors with colors that are very close to each other.
