streamlight hp convert. to p7??

[forrest]

this is something I'm thinking about, the batteries in the streamlight hp are the sub c type with 3.6 volts and around 2800 ma. (nicad or nimh up to 3000ma.

) I can heatsink with an aluminum slug, the reflector ( aluminum, op at base and smooth towards the top) will work as the opening will fit. I have a few of these lights with chargers and a fast charger and several of the battery packs. These lights are nice/ very well built and compact. i was thinking about first doing a direct drive then possibly go with a driver with 2 modes (high/low) what do you guys think?? thanx for any info!

What do you mean what do we think? Do it and let us know how it goes!

What's up with the edit button? How'd that get there? :thinking:

LOL, I pushed it thinking I was promoted to Mod. :tinfoil:

O/K, Fine, I'll do it! (edit)

Sounds cool

O/k got the p7 mounted in the Hp and it has an enormous bright flood but not much throw , there is a dark ugly hole in the center, question, if I move the led farther up into the reflector will this improve the throw/tighten the center spot? Right now it's at the very lowest at the base of the reflector, also I'm using the stock batt. pack which is 4.0volts 1600ma. fully charged, if I go to the 3000ma. batt. do you guys think it will give even more lumen's? ( p=E x I ) Any advice sure would be appreciated! Thanx!, will try to post-up some picts. beam shots soon.

here's a beam shot, I hope it comes up , first time doing this, what in the world causes this??

If you change to a higher-capacity battery in this setup, you won't get any more lumens, but runtime will go up. Yeah, try moving the reflector up and down relative to the P7.

BTW, try to keep your pics to 800 pixels wide or less, so that people using lower-res monitors won't have to horizontally scroll to see it all.

Here's some of my converted to p7 streamlight HP compared to the romison rc t5 (converted with the shark/remora), the hp is awesome, probably brighter and I can adjust the beam also , finally got eh led set so it will shoot a nice hot spot! The one with the bullit is the rom. t5 also,

very happy!

After going outside with this hp and comparing it with the t5, man this p7 in this hp blows away my t5 even with the shark upgrade I did on it! It was quite difficult to upgrade this hp light , it uses a bi-pin bulb, but with patience and tedious work I finally got it, still have to run it a while and get the bugs out

Hey Forrest,
I am very interested in how you did this. Any chance you could takes some pics of your build illustrating how you did it?

Congrats on a great idea!

 

[forrest]

Here's a few. This was this first one I did. It's kinda crude, so the next one will be better. Imagine a flashlight that throws like a task force cree and a romison rc t4 with the spill, that's pretty much what this does in one flashlight!

I cut and shaped the large round disc from an aluminum plate and also cut a small piece from a aluminum rod to attach the emitter and used artic silver to epoxy that to the disc, also had to use two alum. rivets and a small screw to stabilize the whole thing because of the "hump " inside the housing, and artic silver grease to conduct the disc to the housing and the spring to the head. I left the light on for an hour and the outside of the head got pretty warm so 'm satisfied that it's sinking the heat well, run time is beyond that hour also! hope this helps!

Yes. The bulb's filament sat higher in the reflector than the dies of the P7.

EDIT: reading the rest of the thread, I see you alreay figured that out. Usually I'm useful.

 

[forrest]

It;s also somewhat focusable, Of course I had to enlarge the hole in the reflector thus somewhat disabling it from using the original bi-pin incad. bulb, although it might be possible

 

[rolltide]

Thanks Forrest for the pics and the explanation. I might have to try something like that myself.

Cool. Nice mod... thanks taking the time to post this..

So your not really using a heatsink? Just a small aluminum plate? Does it heat up a lot?
