I decided to get on the SSC P7 train as soon as I read about this new emitter. It's intended to be running at 2.8 Ampere with a vf of about 3.6 Volt.
Specs of the the emitter: (from LiteManias sales thread)
Z-POWER P7, 10watt LED CSXPI
- Pure White (6,300k)
- Flux Typ. : 700lm@2,800mA, 400lm@1,400mA
- Flux Max. : 900lm@2,800mA
- Vf Typ. : 3.6V@2,800mA, 3.3V(@1,400mA)
- Vf Max. : 4.2V
- Radia. Angle : FWHM 130 deg.
I got the emitter from dealer LiteMania, here:
http://www.cpfmarketplace.com/mp/showthread.php?t=176067
I put it in a 3D Maglite as I intended to use NiMH cells to drive the emitter to spec at ~2.8A. I have one 1D Maglite I intend to use another SSC P7 in, running on one D-size LiION cell. I also plan to mod one of my Tiablo A9 or A8 with an orange peel reflector and one SSC P7 running on one 18650 LiION. The emitter can be used with heatsinks from H22A http://www.candlepowerforums.com/vb/showthread.php?t=160483.
For the emitter to fit on the heatsink it must be modded some. I dremeled the led centering ridges down so they were level with the pedestal, then I cut away the outer walls on the opposing holes for the leads. That's necessary to make room for the leads so they reach the trimmed down legs of the emitter. There is a slight hole in the hotspot when focussed for max throw. When focussed out a bit the hole disappears. I don't mind that tendency to look like a donut, but others might take offense with the beam.
On a white wall @ 1 metre compared to my Tiablo A9. The spill area is ~4 times that of the A9 and it's just as bright!
On a white wall @ 1 metre compared to my very modded SSC P4 Maglite running @ 1.2A. That SSC P4 Mag is very, very bright but it looks weak and pathetic beside the SSC P7 Mag! The spill from the SSC P7 at 1 metre is about 3 times brighter, ~280 lux versus the SSC P4 that produce ~95 lux.
Outdoor beamshots.
All camera settings are fixed in manual mode. 8 sec exposures, white balance on daylight/sunshine. Manual focus.
The lights used for outdoor beamshots.
From the left in the photo below:
1. 4D Maglite with OSRAM 64440 IRC 50W radial bulb, KIU bipin adapter,
FM cellholder, smooth alu reflector. Running on 12 Eneloop. The 50 W IRC
Halostar equals a 75 W ordinary OSRAM halogen bulb.
2. 3D Maglite with SSC P7 emitter running @ ~2.7A. 3 NiMH cells. UCL-lens.
3. 1D Maglite with SSC P4 emitter running @ 1.2A. 1 D-size LiION cell. UCL-lens.
4. RaidFire Spear. CREE Q5 WC running @ 1.2A. One 18650 LiION cell.
All Mags with low resistance springs. I picked these three comparison lights because they represent both very bright incans, one of the best led throwers and the SSC P4 modded Mag is somewhat commonplace (though this one is a bit brighter than the various commercial dropins).
First setting.
Reference shot. First setting. No light.Nice moonlight, dramatic colours.
Reference shot. First setting. Stock 3D Maglite.
Second setting. A 250 m stretch of very dark country road. Moonlit clouds.
Impressive little bugger, this SSC P7. Isn't it? When driven to spec a wild guess would be +700 torch Lumen.
Update 2008-04-13
I decided to make the light 'regulated', I'm going to use this with 3 x D NiMH cells or 4 x C NiMH cells so NetKidz elegant AMC7135 based solution will work great (and it does, I've been using for a few days). It's one 1Ampere multimode driver with a slaved 1.4 Ampere board. Link: http://www.candlepowerforums.com/vb/...d.php?t=192677
The difference in brightness between 2.3-2.4A and 2.8A is negligible to me. It's a few thousand lux in total output, but it runs cooler and longer. And I get low, medium and strobe.
