1W Luxeon with BB700?

Chief_Wiggum · Aug 18, 2003

I've seen this combo, but my question is how viable is it? I know the standard 1W has a max current rating of 350mA so how is the LED surviving at 700mA?

Another related question, in 3AA direct drive mode about how much current does a 1W emitter pull?

Thanks for the info.

Chief, I believe Charlie's (Mr B) LGI drives the lux at about 900 mA to 1 amp and they are still doing ok.

Awesome. E-can + E1e + BB700 + 1W here I come!

The MadMax+ drives a 1 W at ~800 mA.

Yep, MM+ drives the 1W at 800 mA, but it is only happening when the batteries are fresh. After that, it is down hill from there.

Sort of on topic, what's the difference between the MM+ and the MM+ wide open?

Rothrandir · Aug 18, 2003

wide open means that there is no pot, so it is stuck at full power. whereas the regular has a pot so you can adjust it.

chief, don't worry about a bb700, i like driving my 1watters somewhere around 1.2amps /ubbthreads/images/graemlins/grin.gif

I was wondering this too. Does anybody know the answer?

MrBulk's LGI is a 3AA direct drive light. /ubbthreads/images/graemlins/smile.gif

/ubbthreads/images/graemlins/ohgeez.gif Thanks Chief!

Concede: I compared 3aa alk brightness to 2aa mm+, both with nx05, and same batch 1w, 3aa a tad brighter in the beginning.

Chief_Wiggum · Aug 18, 2003

Then did the MM+ maintain brightness longer than the 3aa? I'm now sorta wondering if I should go with a MM+. Anyone have any idea how it'd be with the 1W + single CR123?

Look in the Reviews Forum for a runtime plot for the miniminimag.

I didn't do a runtime comparison, since I have no cooling compound to put in the MM+ sandwich.

Gothca. Thanks, Roy. Found the runtime plots.
