Hmmm, 2s2p emitters, XHP70/50 anyone 
Any driver for a 6v led, with 9~12v (or 15v to be safe) input should be fine.

Have you considered some sort of basic jig to hold a reflector and control the depth of your cutting/sanding so they all end up the same?
Only in my head have I been thinking of an alternate way to machine the flats. I only have a cheap vice for my mill which is the main problem, that and me of course. 
Definitely subscribing. 
How do you protect the finish from the tailings?
I haven't had a problem touch wood so far. Machining into the reflector gives a cleaner cut though leaving me to make less of a mess cleaning up the very edge of the reflector surface.
I’m sorry, but it would appear you have jumped the start, & voided your entry.
Better luck next year.
j/k!
Best of luck! 
Quads make great beam patterns. Well, the one quad I have does. Wish I had some advice on the reflector challenges, but that is way out of my league.
If you have one of the old, good "3T6" drivers, you would be good to go. Just piggy back a Attiny13a on it to get the UI you want..
The reflectors look pretty good to me. I'd be pretty stoked if I attempted the same and it came out as well.
That’s where the welding mask comes in handy !
Ignore my advice, it looks like I’m you’re only competition right now. I probably subconsciously gave you a bad idea, since my subconscious probably already knew it was going to have me enter. That guy’s always doing things when I’m not paying attention.
Just kidding, although I do have to say, I’m liking my chances for at least getting second place. :bigsmile:
I'm a judge in the comp so yes you will be second. I'll be third out of the two entrants. 
The free wifi runs out in a few hours so heres a quick update. We spent most of the day here and are heading down to the Hudson river tonight for the fireworks. The Intrepid aircraft carrier and other exhibits on and around it was an amazing experience.
The start of another great build from the master. Looking forward to it.
Is that you in the suspicious looking hoody by the Dasani machine?
No, I was behind the camera but I believe we need n10siverns zombie gun slayinator along with your laser gun light to fight the hooded evil ones.
I didn’t recognize either of the two grinners looking at the camera.
Ones a pom. Ones my dad. Sometimes I dont recognize them either.
Last nights festivities on the Hudson river. Later it was down to Times Square to discover the Revlon picture love thingy whatchamacallit.
