what do I need to drive my Nichias?

Building a triple 219B light, this one:

L2 voltage bin.
What exactly do I need to power it in series?
I was planing on 2 18650s in series for power.
hoping to run it at 2.5-3 amps, it will have extreme heatsinkage.

Can I just use a LM350 and a resistor or will that get too hot?
it only needs 1 mode.

I'd consider looking at Mountain Electronics. Their Qlite driver is 3.04 amps stock, and you can have them add 7135's and modify the modes. Done! I've built a few triples from these components, in various amperages.

Are your leds in series or parallel?

They are all made parallel. Never used the gold jumper bars that I purchased with the mpcb's, just used solder to bridge the contacts. Parallel is bridging 4 contacts. Look at the International outdoor page, it shows this clearly.

No issues with light output variance due to Vf tolerance?

None that I can detect with my eyes
