Time for a new prototype. UPDATING. New pics

As you know Dragon series flashlights has been discontinued, so new ones are about to "see the light".
This one is the prototype of Barbolight U-O9.
There is no knurling, but the definitive model will have.
Head is just 54mm diameter thanks to the IMS optics, 20 mm ones.
Tailcap ( with momentary) is 35mm, push-button is machined from Ertacetal-C, AKA Delrin.
Will post beamshots before Friday, comparing vs Fraen optics used on DragonLED.

There will be just ONE colour available, HAIII

Definitive dimensions,

210 mm/8,26 inch, lenght
Head diameter: 54mm/2,12 inch.
Tailcap diameter: 35mm/1,37 inch.
Body diameter: 30mm/1,18 inch

............. looks great ! /ubbthreads/images/graemlins/happy14.gif

can´t wait to see the beamshots /ubbthreads/images/graemlins/smile.gif

p.s.: HAIII rules !

Re: Time for a new prototype pic

*one of the noobs sticks his neck out*
For us newbs, could you post some more information?

Re: Time for a new prototype pic

3,6 V 4500 NiMH battery pack (alkalines can be used). Direct drive, three LS III, 20mm IMS optics. 20 ATM water resistant, 6082T6 alloy on body, 7075 T651 on "mistery part"
copper sandwich for thermal management, all contacts made from maritinme standards stainless steel... need more info?

... 12-24V charger, 90-240 50-60 Hz charger.

Re: Time for a new prototype pic

That should be enough /ubbthreads/images/graemlins/smile.gif I had no idea what I was looking at is all. Thanks.

Re: Time for a new prototype pic

Would you be so kind as to give us it's dimensions? How big is the sucka? ;-)

Thanks.

Re: Time for a new prototype pic

can't wait to see beam comparison

Re: Time for a new prototype pic

Info updated with definitive dimensions

Re: Time for a new prototype pic

by the way, Barbarin, anything new about the U-21 ? /ubbthreads/images/graemlins/smile.gif /ubbthreads/images/graemlins/smile.gif

Re: Time for a new prototype pic

Here are the beamshots, but it can be called too a beam study, comparing Fraen Trilens vs 3 IMS optics.
Same manual setting has beenm used on the camera, same battery pack, same diodes, same heatsink.
Unfortunately the prototype has been done using 17mm optics instead of the 20mm ones, wich are the definitives. According to IMS datasheets the wider ones are arround 20% more efficient, so light output should increase on that proportion.
The final product will be using 20mm optics.

Tomorrow will post pics showing beamshots on the "real world" (street, road, bathroom -a classical-, etc...)



As you can see the hot-spots are almost similar (larger diameter on Fraen, narrower and brighter on IMS). Where I find the main difference is on the sidespill, being IMS way brighter than Fraen. On the other hand Fraen does have a distinctive corona, but the sidespill is poor when compared to reflectors.

Sooner than you think, later than I would like. I'm on it, and that is a product that is going to be released.

My target is the output of a 10 Watt HID, and will get it.

Re: Time for a new prototype pic

Whatever happened to the headlamp you were working on?

Re: Time for a new prototype pic

Wow, the output of a 10 watt HID, that is awesome. I want one.

Too busy! But I have been thinking a lot on a headlamp. At least here are the guidelines I will follow the day I decide to make one.

1. All in head (batts included)
2. AA powered.
3. Single Lux III
4. Dimmable.
5. Alloy made. at least 2 ATM water resistant.

As you can see hard anodizing has been finished on definitive bodies.
You can apreciate too the antirroll clip, designed for pocket, and to make easier to switch on by twisting. Some diver woman reported to find hard to twist thsi kind of switch unders pressure. This clip allows better gripping, has a hole for landyard while allowing stand uo tailcap, and acts as antirrolling. Made from 7075 T651 alloy, will be blue anodized.






Comments are always welcome!

Hi barbarin,

this just looks great !!!! /ubbthreads/images/graemlins/smile.gif /ubbthreads/images/graemlins/smile.gif /ubbthreads/images/graemlins/smile.gif

Will the U-21 body look similar to this one (but only bigger) ?

-Nobbe

U-21 Diemnsions:

Head: 68mm
Lenght 250mm

Barbarin,

Awesome,,,any idea when they will be ready?

thanks barbarin /ubbthreads/images/graemlins/smile.gif

- 250mm still will be quite compact for this amount of light output !!
