Red-orange mega death ray!

[evan9162]

I just finished my 1W red-orange mega death ray!

It's well hidden inside this 2C maglite.

That emitter is the one I freed from a 1W R-O star, T-binned for brightness (60-89 lumens!). It's running direct drive off 2 C cells, running over 400mA. The Ray-O-Vac alkaline C cells I picked up measured 3.4V fresh with no load!


Time to light this bad boy up!

From left to right - Death ray (obviously), 1W HD (Q2J) in a mag 3D at 1.2A, 5W HD (V3T) in a mag at 700mA.

And here, up against a 5W SE royal blue at 800mA:

And with wide focus on the death ray:

So this beast is showing up severely overdriven 1W whites for spot brighness, and is rivalling 5Wers for sheer light output.

Wow! Nice mod!!!

A bit of advice. I was walking down the street once with a r/o on 2AA with NX05, and had a group of teenagers come up to me asking to see my laser. /ubbthreads/images/graemlins/grin.gif

With a beast like yours, you could easily find it getting confiscated by the cops. /ubbthreads/images/graemlins/smile.gif

Nice. /ubbthreads/images/graemlins/thumbsup.gif How tight can you focus it over a long distance (say outdoors)?

Lux,

No kidding! I could impersonate a squad car with this and my 5W royal blue!

Mike,

I'm afraid to shine this thing outside, as my porch overlooks a highway. I don't want anyone to think they're getting pulled over!. Lemme do a quick check...

At 24', the spot is 2' across. Consulting my trig, that gives about a 4.5 degree beam.

Evil. Pure Evil. I love it!

I'm afraid I'll get in trouble one of these days with these high powered LED's. It's a good thing I've been to busy to mod them into anythign yet....

You're using the original MAG reflector, not one of the little standard beam shapers, right?

NICE result.

 

[IsaacHayes]

How well do plain red luxeons do? Are they not as bright? /ubbthreads/images/graemlins/frown.gif

Yep, using the original reflector, I just cut the tube off the end of the reflector.

Plain red won't be as bright. Red high domes average 44 lumens, while red-orange HD's average 55 lumens. This one is T-binned, so is supposed to output 60-90 lumens. I'll split the difference and call it 75 /ubbthreads/images/graemlins/grin.gif, and at rated current /ubbthreads/images/graemlins/cool.gif. Put THAT in your luxeon 3 and smoke it! /ubbthreads/images/graemlins/wink.gif

Even after running for about 20 minutes, this thing isn't warming up AT ALL.

I suppose this means that we wont be hearing about any further installments of your frigid luxeon experiments. /ubbthreads/images/graemlins/grin.gif
BTW, I am thinking about putting my remaining "T" bin red-orange in an ARC LS body modded to use a MM reflector.

 

[IsaacHayes]

Are the majority of R/O luxeons T binned or did you guys get lucky?

Which color looks best? Red or Red/O? More evil? /ubbthreads/images/graemlins/grin.gif

I believe that we got very lucky. I've heard no reports of any binned higher. I had fun asking if anyone had seen higher in the following thread: T bin 1W
"Evil" is not an engineering parameter so I am afraid that I cannot help you with this question /ubbthreads/images/graemlins/wink.gif

 

[Lux Luthor]

Red/orange also appears brighter than red, since most objects tend to be more "yellowish" than pure red.

 

[evan9162]

I'm not sure about the evil thing. I'm sure my red-orange was infused with plenty of evil, direct from the factory. Who knows, maybe Lumileds infuses the reds with more evil to make up for their slightly lower light output /ubbthreads/images/graemlins/tongue.gif

 

[IsaacHayes]

/ubbthreads/images/graemlins/tongue.gif The color looks red to me in your pictures. A bit on the orange side, but defiantly still red. Is there not that huge of a difference betwen red & r/o? It's not like red vs orange right? that's why they call it red-orange. Am I correct?

 

[evan9162]

It's not that big of a difference. The red-orange is spec'ed at around 617nm, while the red is at 627nm.

 

[IsaacHayes]

I can't help but ask for outside pictures. Perhaps zapping someones house or building afar. Reflecting off street signs... etc!

 

[Zelandeth]

Oh, I sooo have to try that...

Nice mod! Have to admit, even without optics, the sheer output of the 1W R/O I have here impressed me! Seems to take overdriving better, doesn't get as hot as the 1W blue and white I have here at equivilant current ratings.

 

[Rothrandir]

actually, the red, red/orange, and amber luxeons are very particular about overdriving /ubbthreads/images/graemlins/frown.gif
heat reduces their output much more than their siblings /ubbthreads/images/graemlins/frown.gif

 

[evan9162]

Yes indeed. The "Warm" luxeons (red/r-o/amber) are based on materials that have a drastic reduction in light output when they heat up. They also have a higher junction-slug thermal resistance (making it harder to keep the junction cool), AND their Vf increases at a much higher rate than the Vf of the "cold" (white/blue/green) luxeons.

All of this screams "RUN AT 350mA!!!" for the "warm" colored luxeons. /ubbthreads/images/graemlins/tongue.gif
