*BLF LT1 Lantern Project) (updated Nov,17,2020)

Well, a good anodize layer is generally pretty tough already. The o-ring or “bump ring” isn’t going to protect from severe damage from abuse or long falls, but it should be enough to help with short falls and tip-overs.

I don’t know, that’s a good question. If the powder will mix with silicone you could mix it up & load it in a large syringe, then apply it in the groove for a more permanent bumper.

That would work I think.

Edit:
Best I recall silicon caulk has about a 15 minute window befor it starts to ‘skin over’. That should be enough time.

Should be completely dry in 24 hours…. unless the addition of GITD powder changes any of that???

CRX has done a lot with GITD powders. I can’t remember him ever saying if he has tried Silicone. Maybe somebody needs to try it and let us know! :smiley:

If CRX doesn’t chime in here in a bit I’ll PM him & ask.

from…. CRX Flashlight Builds post #8

“I use a mix of aqua glow powder & silicone or resin, also the glow tape can be useful for sticking to the inside of the flashlight head.”

Its there for added bumper protection when tipped over or knocked around, ( to help protect the anodized aluminum head from dings & chips. Lanterns get clunked around a lot at camps. Also it adds to the look and customization for colors, and it wont cost any more than without it. ( it was suggested by a few members of adding the rubber o-ring a month or so back.

It adds some pizazz to the appearance!

Thanks MtnDon… :+1:

Yep… straight from CRX himself….

Yep… the bumper was a great idea. It will certainly take the shock of a tip over thus saving dings on the lip of the top.

A win/win…. good looks as well as protection. :beer:

Put me on the list for 2 thanks.

I’m in for two.

:+1: … That brings you up to 6 weklund, are you gifting a few like I am? I got my name in for 6 too.

I’m thinking people are gonna love these. :beer:

I’m considering gifting too. With the relatively low current, built in charger, and cells running in parallel, this should be a safe light for people not too familiar with lithium cells.

Put me on the list one for sure. Possibly two. Thanks!

Yep … a few for gifts and a few for friends. Great endeavor. I am very pleased with the final results.

I have tried so hard to resist, but I’m asking to be put on the list for two more please. I had one already, so this will make three.

Yeah, I agree with you guys; the final result is pretty amazing. :+1:
These should make killer gifts for the right people who will put them to good use. :beer:

Very Nice!
Please put me down for 3 more.
a total of 4. Thanks!

Regarding the GITD o-ring. What would the dimensions need to be? Roughly speaking.
I know 42mm OD x 1.5mm GITD o-rings are quite common (Fasttech for example) but they’re obviously too small for our purpose. I think
So the Q8 head is 59mm but the body is 50mm? So would something in the 50mm ballpark work?
Edit: Looks like I forgot what the LT1 looks like and how large the head is. So something closer to 60mm is probably needed? Or even bigger?

One of the largest I found was a “50mm” GITD o-ring from crazy-factory.
Due note they’re sized to fit snugly on plugs of the stated size hence the quote marks on the size. It’s thickness isn’t listed either so it might be a 1mm jobbie which would a bit wimpy.

Just for shit’s and giggles, here’s something a bit chunkier, a GITD hood latch which dimensions according to the description are 50mm OD x 5mm.
If someone’s interested in those, looks like they’ve got a discount on their website. 3$ for 2 and 5$ for 4 (instead of 6.5$ for 4 on Ebay).
A bit too expensive for me as they come from the USA. 13-15$ for shipping, oof.

I like the sleek look of the first prototype, but the new design is probably more practical. It seems it should weigh a bit less and it’s nice how the handle can be folded in. It might make things a little weird for how I usually carry it though; I tend to loop the handle over two fingers. Not sure what to think about the bumper; will have to see it.
