Hooray!!
I am in :)
Not yet decided if I want to build another aluminum hosing or to try enter the world of 3D printing.
Does it counts as "outside services" if I am using the 3D printer in my office?
PS: thanks for everyone involved 
My feeling would be that using a tool/etc. that you have access to and permission to use is not an outside service. Otherwise it would exclude maker spaces and such.
This is of course not an official ruling, just my thoughts.
No. You can use it.
Glad to hear it! Your build for the 2019 / 7th O-L contest was awesome!
Building it under a bridge or where ever the heck that public property was… WOW!
I am in . Just gotta see if I can get the stuff to make it work .
Hey, glad to see the contest running this year again 
Thanks Hoop for taking the lead and to the organizers in the previous years for keeping it alive as well!
I will still decide on entering or not, but if I do, it will probably be with something modded 
Meanwhile, good luck to all the contestants and good work too 
Need some ammo for your build?
No, you’ve got plenty already?
Then maybe you could spare a round and do like DB Custom did in the 1st annual Old Lumens challenge!
Now that’s a shiny bullet.
We have sponsors now, (Thank you sponsors!) but what we still need are participants!
I am still not exactly sure of my entry this year, I have a general concept idea. As in previous years, it will fit into the Hand-Made category and will make use of some Wooden components. Nothing new for me there.
My topic is located here, but there is nothing I have not already said there.
This year I will try to save a beloved headlamp
Thank you Hoop for making this to happen
Here is my only memory of Old Lumens…Hopefully we will meet some day…

Hey Vinh, nice to see you around! Your store is an inspiration.
Thanks for being a sponsor.
Very cool and very generous, Vinh.
That’s cool that you have an Old-Lumens creation Vinh.
Many has come and go…Sometime when I slow down to reminisce it makes my heart a bit heavy.
Marshalls of goinggear used to send me gift lights with my name laser engraved…
I have a hard time building a collection of my own because $$$ always gets in the way….Yet I have never sold a single light gifted to me. They are all the most special…
Old Lumens was a wonderful man that I respected from the early days. I am glad there is this tradition in practice annually to honor him.
Hi, I’m thinking about joining the machine made category. Is making a drop-in acceptable, even though it isn’t a complete light?
Making a drop-in is an acceptable entry for the Modified Light category. To enter the Machine Made category, the entire light housing and drop-in would need to be made by you.
For clarification, I believe a battery holder similar to the plastic type in this link would be suitable for a Challenge entry. Correct?
Battery carriers of this type are allowed.
