JUDGING CRITERIA: (may be subject to changes)
Up to 10 points are awarded in each of the following five categories:

Skill Level / Build Quality: Judged with consideration to the person’s access to tools, materials and abilities. Is the finished build functional looking good? Was it difficult to make? Was the craftsmanship top notch with the tools used?
-
Uniqueness / Inventiveness / Innovation: Is the light unique, one of a kind, or does it operate in a special way? Can something similar be readily purchased? Were new technical innovations introduced? Were new firmware, drivers, or PCBs created?
-
Build Thread Quality: Did the contestant do a good job of showing and explaining the steps involved in the build? Were the difficulties encountered along the way documented and resolved? Was it easy to follow along?
-
Shown Operational: Did the contestant show the light operating, describe its functions, take beam shots, videos, etc.?
-
Subjective Evaluation / Bonus Points: The judge may assign these points at their discretion.
PEOPLE’S CHOICE AWARDS:
There’s more than one way to win! In addition to the official judgement, a thread will be created which contains a poll, and the BLF community will vote for their favorite build. This poll will run for fourteen days. Contest participants may vote for other entrants but not for themselves.
PRIZE SELECTION:
The winner of the Hand Made category has 1st choice of prize, followed by winner of the Machine Made category, followed by winner of the Modified Light category.
Runner up of the Hand Made category has the 4th choice of prize, followed by runner up of the Machine Made category, followed by runner up of the Modified Light category. Prize selection will continue in this way as long as any prizes are left to award.
