Wow, nice! I would be interested in the titanium one

That is a great link! Thank you for posting it.

EDIT: And with that being my 100th post, I have gone from being "enlightened" to a "flashaholic". I need one of these replica NASA flashlights to celebrate!

Holy cow... ACR FA-5 #1024 is valued $26290 Must be IT crowd was fighting for this one
I hope reproduction lights will be a bit cheaper If price will be reasonable, I am in for both.

Yes, pure single mode. Remember that "KISS" principle? It seems it was originated around that time.

Re: You will love this NASA flashlight
Maybe my calculations are wrong but on the Apollo XII every gram on the moon had a cost of 3500 US$. Then why did they used brass, which is almost three times the weight of aluminun? The lights being used on Gemini project were similar penlights with 2xAA batteries, and made from aluminum alloy... so why change to a new and heavier design? After the tragedy of the Apollo I probably they wanted a material less flammable (aluminun will be a flare on pure oxygen atmosphere), and spark proof. Is the only reason I can think of. Nowadays they would have choosen titanium, which was not available on that time. (Check the interesting story behind the SR71 Blackbird and how did CIA managed to get the much needed titanium from the USSR).

Re: You will love this NASA flashlight
i would just like to bump my interest. thats a nice runtime graph, just imagine how well an energizer lithium would do. any kind of timeline on this project? seems to be a lot of interest already. id take whichever metal is available first, brass or titanium.

Dear flashaholics.
Next week you will have information with new runtime charts using NiMH batteries, Energizer L91 and all the test done with a using the XPL-HI Warm White Hi CRI. Also IES files if you want to play with them.
Best regards,
Javier

I can tell you no later than August if finally we decide to move ahead... Which is something that will happen pretty soon, within two weeks.

Update, new runtime chart added. Circuit improved as well as cooling on LED. This version is using the warm white LED that will be used on production. Incredible nice, warm white with high CRI, and hyper efficient, as it is a Cree XML-HI underdriven at 10% of its maximum output.
