The 10th Annual Old Lumens challenge - has officially concluded! Winners have been announced!

That's a wrap! The building period of the 10th Annual Old Lumens Challenge has officially ended.

Thank you to all of this year's participants. It has been a pleasure to witness your effort and creativity!

Judges will now be solicited, and winners chosen, so that prizes can be selected from the prize pool.

If anyone would like to volunteer to judge the contest, please PM this account.

Thanks for the organization and efforts to make this happen :sunglasses:

I anticipated that there might not be as many prizes as entrants. My contingency plan was to offer a prize of my own to sweeten the pot.

As an additional prize I will offer some custom MagLite “shorty” builds which I have been working on for quite a while now. I will offer three in total. You can choose any color of MagLite body.

D Mag shorty, dual bored for dual 18650 in 1S2P configuration, dual constant current drivers with independent Anduril 2 installs, separate spot and flood channels with independent controls.
The switches are integrated into the head.
Spot channel: 3x Osram WF1 behind reflectors, 9 Amps drive current total.
Flood: 3x 219b sw4500k (or if you prefer, dedomed 519A, any CCT) behind diffused TIR optics. 6 Amps drive current total.

The caveat is that these are not ready to ship. I anticipate completion in a couple of months or so.

I’m thrilled to see this is still going strong and see so many old friends doing Justin proud. Cheers y’all!

That sounds like a heck of a prize! Surely worth the wait.

The results are in! Congratulations to everyone who entered this year's challenge.

Congrats and thanks to everyone involved! It’s always a pleasure to see everybody’s projects. YuvalS, yours was such a unique project, I think that was a 1st Place very well earned!

Yes, when I saw how it progressed and worked out I said to myself that it was The First Place Project!

Your lights are nothing to sneeze at, Don, ever. :slight_smile:

Well done everyone and big props to Hoop for being this year’s organiser :beer:

Thanks so much guys. I really hope it drive others to develop a voice-controlled light.

Did someone inform Skylight it is his turn?

Yep, Skylight has been PM'd.

Thanks fellas, it was an honor to organize this year’s challenge and keep it going for another year. I enjoyed the experience.

Organizing the challenge did take quite a bit of time, but mostly because my approach was thorough. The first thing I did was study every prior challenge thread in order to see what the rules were and how they changed over the years. Every contest entry also needed to be examined because not everything was explicitly stated in the rules but could be inferred from the entries. After some deliberation about the rules I drafted this year’s challenge thread. Next I drafted a revised solicitation letter and solicited sponsors. In total, 44 companies were contacted. Seven companies responded and offered a prize. After that it was mostly a matter of maintaining the challenge thread and answering PM’s and such. There was also some housekeeping to do in the archive thread. Next I revised the existing scoresheet, and judges were solicited. Judging took me two full days because of the amount of commentary I made for every build, which formed the basis of my scores. Next I wrote some documentation to help the next organizer.

The work of the previous organizers made my job much easier. Whoever originally put together the contest archive thread, “the” or CRX maybe, had to do a ton of work. There was an existing solicitation letter, existing scoresheet, existing imgur account, and some documentation, to help me along. Revising existing documents and processes is easier than creating new ones from scratch.

Special props to whoever put together the GIF slideshow compilation (data heavy, ~414MB) for the 2020 (8th annual) challenge. That probably took a huge amount of time. I believe it was pinkpanda3310.
