triple reflector from DE for Cree/P7

[lucca brassi]

On base of screen picture I have prepaired blueprint for AluPCB with triple SSC P7. I just start to order some of these reflectors ( I know that I must made bigger hole for P7)
I just like to be sure - has anyone here build lamp with these reflectors , have maybe bamshot pictures? Reflectors are these

or

Best Regards

I have seen a maglite conversion using 3 P7 that looked like it used this reflector.

I always made my own head enclosures because of some heat dissipation details.
Like only to be sure to get uniform round beam with a little hot spot in the centre.

You maybe think this?
CANDLEPOWERFORUMS MAGLITE 3 P7

Yeap, wrong thing, huh?

I know someone who used one of those in a maglite with 3 MC-E's. 30watts, so it chews through the battery, but it's BRIGHT! Focus wasn't as bad as I expected.

Actually I have some ideas to correct beam...but I must simply build it and test it (not just talk )

next thing it is to made lamp based on this (light path it is in the opposite direction)

Yeah, with a driver, you would need about 15.5 volts. Without I ran 3 P7 directly with 9 D batteries about 10.8 volts. I used NiMH, but I would definitely go with LiIon next time.

I am currently working on a custom machined SSC P7 direct drive with 14,400 mah battery pack. The canister will be Delrin and the light head aluminum. Light head will be a huge heat sink.

I have accumulator from here NEWTECS 14.4V /10Ah it is quite small.

length : 179.5mm ; diameter :<80mm; weight : 1,95kg

With fall on step-down switcher 1,5V I have full tension long time. But please don't do that without controller

Not agree quite - LiPo are light (thats part is fine -think small too) but I think that canister it is to much buoyant . I have wing same as DIRZONE for single and I have with in weight pockets 4+4kg . With lamp 4+2(lamp2) - to get balanced rig in that case don't use pocket on right side. Also I have 1,88m and plenty of space to put my canister
LiPo's same capacity 2x(U= 7,4V , I=5000mA ,weight= 270g ) = 0,54kg , price is the same : 119&#8364; . But battery is more tricky , need protective circuit , maybe overheat....explode

I have in work 2 tanks and several lids ( lamp testing ) at local workshop - H new style lids in exeption with sliding reed switch which looks like normal toggle switch and some other changes which I think they are useful.Plastic it is the same like yours.

Light head will be a huge heat sink.

read this HEATSINKS and find some online calculators- I think you'll find out what the fake is. It don't need to be to big but it need right waterflow.

I have think to put in lamp head wet contacts switch - just to reduce light power to lets say about 25% - just enough to came out of water at night dive to the shore (rocky) and not to overheat/burn lamp.

Yesterday I finally got reflectors from DE ! (1,5 month!) I have started to route PCB (now I finally have pieces to mesure them) for LED still I have to start drawing constant current driver PCB.

I have thought that I can maybe made at that reflector variable focus with some more hacking on reflector...
