this'll be my second build (first blu-ray) just wanted to know the differences between the couple of drivers floating around.. any one got a preference? the only ones i know about are the rckstr and the lava flex.. woundering if one is better for the power im looking for or if they are both about the same. also its in an aixiz module.. dont know if that changes anything.. thanks for all the help :)

I use the Rkcstr driver for mine :p set at 97mA the 803t should last a LONG time and burned quite well

how big a power supply are you runnig it on? (or does that matter?) :-/

I think if your going to use a 9V then go with the Rkcstr, not too sure on the Lava

i was planning on putting it in a flashlight with space for 1 AA i think.. so i could use a lith with 3.7.. unless thats not enough for either then i may be able to rig somthing up..

Well, you can completely disregard my statement because of bias, but I believe it's a straight answer:

It depends on what you want to do.  Either driver works well, provided you give it the right conditions.  But, what type of power source are you using (battery?  AC adapter?  PSU), what voltage and what current do you intend to drive your diode (for mine, anyway)?

If you can use 2-3 lithium rechargeables or an AC adapter, mine will be fine.  If you want to use one lithium rechargeable or a couple alkalines or few NiMH, then DrLavas would be better for you.

I think the Lava drive only requires 2.5V where the rkcstr driver requires about 7V input for the 803t

not too sure :-/ maybe rkcstr can clear that up

what if i just hook up an LM317 and a 10 ohm resister to a 9v?

That would work. It would give you 125mA... Though you'll want to put some capacitors in there to dampen the voltage spikes on startup. (you'll likely blow your diode without one.) People also like to add a reverse polarity protection diode in so you don't kill your 317t when you do something stupid. A bleeder resistor across the output capacitor is a nice touch too, since otherwise you might forget to short out the cap, then expose your diode to the full charge of the cap when you connect it up.

how many mW would that be? (still dont know all the math on that yet lol :p)

at 125mA anywhere from about 90mW to....130mW these diodes vary quite a bit

I run my PHR-803T diode in a heatsink made by Jayrob, with DrLava's Flexdrive v3 @ 150mA, powered by 3 AAA batteries.

It runs great, doesn't heat up, and burns way better than my Sony 16x red diode running off a rckstr @ 350mA, powered with 4 AAA batteries.

Although now that I think about it, that's probably not quite enough voltage to drive that diode with a rckstr eh?

I use a rkcstr 150mA driver with 6 AAA batteries, and it works great.  It lights a match pretty fast when focused and it stings skin unfocused.  It also heats up pretty quickly.  About 15 seconds of continuous use is enough to heat the aixiz module to what I would consider not hot but quite warm.

Acually, it doesn't matter. The current decides. Either way, 150mA will kill it in the same amount of time. Trust me, it will not last a long time at 150mA. I say stay at 100mA or lower, or 110mA with a good heatsink. That is if you want it to last.

You could use one of these with a lavadrive (needs about 3.5 volts, it's regulated),
