Sold/Expired Feeler: MagCTower

[download]

All we know Mag lack of heatsink for MagLED upgraded or other retrofit dropin Led.
Here is the :toilet: idea, just replace the plactic part to this black aluminium heatsink.
All you need the tool is 2mm Hex Key and be patient to open & put it back only.
And the most important thing is to keep the quick focusing system work as usual.
The result is . You can drive your MagC as hard as possible because the tower transfer the heat to the MagC body.
No more frosty lens. Stay bright. :devil:

Here is the 30mins. test run of 2x MagC with MagLED 4cell & UCL at Room Temp. 27 degrees C & RH 90% .
Green MagC with stock plastic tower. (No mod.)
HA MagC modded with MagCTower Heatsink.

Here we go....

The MagCTower direct contact to the MagC body, you know where the heat goes.

Steam were build up by heat all over the reflector & Lens at stock Mag.

The frosty lens reduce a lot of throw.

interest? :thanks:

Charles - I would be in for a couple. This looks like a nice mod for those that might want to keep their MagLED close to stock. How much is involved in changing out the part? Can this design be carried over to the D Mags? Thanks. Kirk

download, I think I understand what you're describing, but I'm still a little fuzzy. Do you mind posting a few pictures of it installed inside the maglite body and another of it installed outside the mag body, but still on the switch assembly? This would really help me visualize your words.

Hi Kirk,
It does not work MagLED only, whatever you dropin LED is OK too. So it will be very easy to upgrade the LED module.
For the installation of the heatsink: a 2mm Hex key, a flat head screw driver & a little bit lubricant that all you need.
No soldering & dremel job. 5-10 mins will finish the mod.
Unfortunately, current D-size Mag have different design. The heatsink has to re-design all over again.

Hi JamisonM,
The installed heatsink show at the photo, I will show more detail after starting sell.
Stay tuned.

:thanks:

PM when selling please

Now that's a good idea... :thumbsup: So what's the price going to be?

Don't worry, it will come very soon, not months, not weeks, only days. :santa:
Price should be around $1X + shipping. Reasonable? :thinking:

:thanks:

 

[JamisonM]

I think I see what you're talking about now download. Before saying anything though, I'll wait for more details.

I would be interested. Please PM me when it becomes available.
This picture might help since I have the C size switch housing in half to insert a Kiu Alumin base but in your case it would be your black tower

 

[Niteowl]

Nice Charles, I like it. I'd be in for at least one most likely two. I like how sturdy it is and might put one in an ROP,.... just because.

Well, now I have a question.
If the purpose is to transfer heat and the tower is metal why paint the aluminum black?
Wouldnt there be a better heat transfer with 'bare' aluminum?

I thought a thin Black anodizing surface is better for heat transfer & the moving parts. ....:thinking:.... please correct me if I am wrong.

NewBie got the excellent info!
Thanks

I would be in for at least one, maybe two. Thanks.

There were some studies awhile back on CPF showing that black is indeed better than bare al for heat transfer. Can't find thread.

:thanks: Niteowl, you reminded me to test with stock 5 cell Incandescent bulb drive by 2x Li-ion 18650. Can't imagine the large amount of heat transfer to the body, it may help to save the black plactic inside the tower if drive harder like ROP....

I remember looking at Newbie's post and at first I found the information hard to believe but his temperature readings proved that
Black is better than plain aluminum.
Thank you for the link

Newbie's post tested heat transfer to stationary air via radiation. I don't think conduction to another metal part (i.e. the light body) would necessarily behave the same :thinking:

 

[cnjl3]

'IF' there is a choice I would rather have unpainted aluminum.

 

[Reptilezs]

anodize(any color) has a negligable effect of heat conduction which is the case here. black is only beneficial in a open air enviroment which the inside of a mag body is not.
