No, not really. It's not the same material. Note that sapphire is aluminum oxide, this stuff is aluminum oxynitride. And even in materials with the same chemical formula there are differences. Aluminum oxide in it's ceramic form, IE the stuff commonly used for knifesharpeners and other things, is not transparent and has a different crystal structure than sapphire.

My point wasn't that Al2O3 sapphire was the same as Al oxynitride. The point is that Al oxynitride is definitely closer to sapphire than metallic Al and if one were to consider Al oxinitride to be "transparent Al", then why not also sapphire which is Al2O3? There is no such thing (or even close to it) as transparent "metallic" Al. It's like saying CO2 is gaseous diamond just because they both contain carbon. Rather, this Al oxynitride should be considered a kind of ceramic not metal. Of course, ceramics can be both transparent and opaque. Metals are always opaque.

Well, it IS considered a ceramic material. The whole "transparent aluminum" thing is largely a marketing/media thing and as such is rather misleading. It would be more accurate if they referred to it as "transparent alumina".

Yes, on closer inspection the sales brochure link even says ALON optical ceramic. Unfortunately for materials selection, and Eagletac, there are no good leads or hot trails on the quest for something that is both highly transparent and highly conductive.
 
So since this was on pre-order at one point, and now it's not.....does anyone still know a confirmed release date???
 
It was never a pre-order. According to 4sevens, it was accidentally visible on their site and some of us snuck in our orders, but 4Sevens did not announce an pre-order for this light.
 
New information is up on the Dealer's Corner, now being called the MX (P7) and MX2 (tri-R2 version).

EDIT: Correction, see post no. 138, below.

That's interesting... My bet was that it would be called an F10L2 or something like that.

Do you have a pic of this flashlight? Does it put out 900 lumens?



How much is this EagleTac Megalight supposed to sell for?

If it's in the $100 to $200 I might have to get one.


When is it supposed to come out?


Someone said March or April......of this year? (Because it's already March)
