Yeah, it's definitely a bit smaller in diameter and slightly thinner, but look at what you give up.
4-6 hours instead of 40-50 hours
5.5 lumens instead of 1.5 / 18 / 80 lumens
$40 vs $25
Blue light vs. white light.
For me, the advantages to saving a few cubic millimeters in space is nothing compared to what it lost. I like the Arc, I own three of them in various generations but I have to concede that it's a dinosaur compared to the new generations of AAA LED's.[/QUOTE]
Eh, the iTP/Maratac in my opinion doesn't even measure up to my E01, those 40-50 hours claimed on low? Bogus. Unless you never turn it off. The E01 has way more real world runtime with it's (initially) higher output. And the "MarEOS" sure as heck doesn't say "drop me, I can take it" like my E01 or my Peak Eiger for that matter.
