P7 Led in 2.5" Throwmaster, long range beamshots!

[AlexGT]

I have just finished modding my 2.5 throwmaster reflector to accept a P7 led, the results look good... more updates as soon as I finish playing with it.

Teaser pics...

This thread is worthless without BEAMSHOTS!!!

[AlexGT]

Ok I'm back now!

Imageshack seems to be offline, anyone knows another pic hosting site to upload some pics?

AlexGT -

Seems like it should be much more intense. I'm guessing that you might not have been going for lux but more for beam structure. If that's the case, your Throwmaster looks to be collimating that P7 beautifully.

NICE indeed, sir.

[AlexGT]

The beam is very intense as you will see when compared to a SSC P4 USWOH at 18 feet with closeup.

P7 Mag compared to a Q5 50 x 38 mm aspherical mag at 1.2 amps both on tightest focus



And edited to reduce the brightness of both

[Icebreak]

Wow. I see what you mean. Thanks for posting this.

New pic using Stefan camera settings (F=2.8 / Iso 100 / exp. 8") distance 124 ft



And with a 6 second exposure looks more as what my eyes are seeing.

Did you bore out the opening in the 2.5" head? Did you have to do anything else to it? I tried fitting one to mine but the hole was far too small.

[AlexGT]

Yes, I did open it up using a step drill, did it really slow and just enough for the heatsink and led to fit. I also had to rise the heatsink about 1mm using an Oring.

Thanks and good work

nice warm tint with intensity

The tint looks very nice in comparison to the P4 SWO – what tint-bin is the P7?

[AlexGT]

It's photonfanatic's SWOI P7 led, but the tint looks more like the Cree Q5 WG tint which is the one installed in the Aspherical mag, the tint are almost the same.

[AlexGT]

Distance to the wooden fence 263 ft, the house and tree on the other side of the fence are 453 ft. (F=2.8 / Iso 100 / exp. 6 secs.)

The small bridge (Yellow arrow) is 504 ft away.

Nice Outdoor shots! That P7 throws nicely, like an incan.

BTW, Where are they taken? Looks like my old backyard in Houston TX?

[Firecop]

Nicely done! How did you mount the P7 - on an H22 'sink? How does the P7 fit inside the reflector - did it require any modifications?

[AlexGT]

Yep it's Houston, the P7 is mounted on a H22A C Heatsink powered by 2 SOB 1500 for a total of 3amps from 2 Li-ion C cells

I had to bore out the reflector a bit for it to fit.

I keep coming back to this thread checking out the beam shots. The flora behind the little bridge is being well lit at maybe 550'. Easily 1 2/3 football fields. What's impressive is that this is in an urban environment with a lot of local ambient light plus the glow from a metropolitan sky.

Add to this impressive focus of light returning a powerful image the excellent regulation chosen for the torch and it seems that AlexGT really has something pretty darn spectacular here.

AlexGT, remember when we started seeing Luxeon I watters that were 8-10 times more powerful than nichias?

[clg0159]

WOW! The more I see of the P7 the more I wish I could afford one! Nice work. I have been out of Houston for 4 years now, but I still recognize that night sky

[AlexGT]

Had a little oven incident this evening, and since the kitchen was full of smoke I decided it was a good time for beamshots!

[AlexGT]

LOL! And to think we drooled over them! That's probably what we will be saying about the P7 in a few years from now.

Nice work there Alex

[Icarus]

Good job Alex!

I suppose the 2.5" head has a smooth reflector?
In that case I'm surprised you don't get a donut.

Do you have an idea how much more throw you get compared to the 2" reflector?

[AlexGT]

It's a VLOP, you can get a donut if you are focusing for it, I just focused to get a round beam of light, there are some artifacts but the hotspot is about 1/3 the size of a P7 with a standard Mag reflector (I tried it) this alone increases the throw considerably.

Your post convinced me to invest in this head. Thank you.

(now, how do I hide this from the wife?)

If she finds it, the minute you get in trouble, remove the tailcap, stand it up on it's head & tell her it's a vase for the nice flowers you are going to buy her.
