Tease!

Tease!

Be along soon

just waiting for some pics to upload

 

[neilt]

Just when we thought we had the ultimate light!

Damn you Troutie

 

[scar]

click on the photobucket link. Also seen on CPF this orning. Looks good!

Insanely big post

I know you are all fed up with Troutie and his lights And I was not going to post this one at all
and it was because of a post on CPF which I replied to which let the cat out.

This has been ongoing for a while now waiting for a hipflex and got put aside while the XPE lights were done , and Deestas sort of developed .

The Hipflex will be available very soon so it was time to get it ready to recieve it.

The housing was turned from a 38 mm solid bar for the fins and then the cavity milled out
I am really supprised that my mill has kept going after all the abuse it has had.

Then I glued 4 of the CMC holders together with some plastic epoxy these were then used to get the spacing correct for the 4 MCE M bin
Each MCE was to be wired paralel and then the 4 mce in series.

I milled 2 grooves to isolate the mce contacts and for the wires to run in

Then it was mix some AA epoxy and apply to the back of the MCEs and fit them into the housing
The holders did not press on the MCEs so I had to replace the optics to get some pressure on the leds while the AA set.

Then a quick test on my Nflex test rig it all lit up great .

and this is the Hipflex house all ready , they are a bit large 35.6 mm dia
I have left this oversize and will trim it down whae I see how much space it requires
I am going to have a remote switch so no space needed just cable entries .

Next we come to the bar mounts this is using the bars as heat sink too so they were milled to slot in to the fins for a good contact and will be bolted and AA to get good transfer.

It is just waiting for a Hipflex from George and it will be up and running
It does seem to be pretty bright running off the Nflex @ 1000ma
so each led is seeing 250 ma
and the VF of the lot was 11.67v

How many lumens for 16 emmitters @ 250ma

I will be tempted to get a beam shot even @ 250 ma

Oh The optics Have been chosen because they were the only ones I had left.
and are
1 CMC-RS
and 3 CMC- SS

That is "effin' rad"! I can't wait the beamshots!

 

[czarny_kruk]

How many lumens for 16 emmitters @ 250ma

4 Cree MC-E M bin, so min. 430lm * 0,76 (@250ma) * 4 = 1307 lumens min :thumbsup:

Easily beat Lupine Betty, which have only 910 real lumens. Not 1500 as they claim.

Very nice write up and pictures.
Alot more info than the CPF post I saw a few hours ago.
I had been following the CPF thread for a bit and still have the same question.
Will lithium ions be able to provide the amp draw at higher light output levels?
It seems the lithium polymers handle higher draws much better.:thumbsup:
Any estimate of what the amperage draw will be at full power?
Inquiring minds need to know.:crazy:

 

[rkj__]

That looks phenomenal. Well done!

 

[troutie-mtb]

You wont believe the beam shot

I had to do it , a quick visit to the woods .

I only have the Nflex and 18 v drill battery I could use .

Now that is the WOW factor I was expecting 6 months ago that never happened.

and this is @ 250 ma per led ( thanks czarny_kruk for the maths )



Prepare your selves ,



If you have followed my beamshots then You will know the trees on the right middle distance are 75 Mtres away

the trees in the far distance are over 150 mtres away and dont show on many beam shots

untill now


I was expecting as some one commented on CPF a huge wall of light with no throw .

 

[cytoe]

wow. sweet! This was probably asked before...but how do you get the inside corners to be right angles using mill?

Cheers Cytoe , this might sound daft but I chopped them out using a small wood chisel
with the Ledils you only need to square off the top 3 mm

 

[rollertoaster]

holy crap. that is truly amazing. I can't wait to see full amperage!

 

[troutie-mtb]

I think it looks quite cool stood up

 

[emu26]

So your 4 up @ 250 mA has better "useable" light than the triple @ 500mA

Do you think this is because the triple was so damn bright over such a wide area that the reflected light coming back from trail side objects played tricks on the eyes and blinded you to the distant objects?

Do you think these things work better, for our application at least, the lower the input current?

Go on mate, take the triple back out and do the same test at 250mA to see if it changes the "visible" throw you can see

Oh yeah and as I said yesterday, really nice work :thumbsup:

 

[mdsjack]

Tease!

Hype!

 

[riggsy]

bloody hell Chris thats awesome... kinda makes me depressed looking at my sorry set up now

cant wait for pics once its fully up to power

Thanks for the comments

I dont know about the power draw but the makita drill batterys are designed for abuse
fast discharge and charge . and I doubt it will see the full 2800ma much
only to to upset the betty owners .

at full power it will be drawing a tad above 2800ma

and am I right in thinking 3200 lumens ish
