I like the GITD reflector a lot. The price is good. But I wish the magnet was optional, or at least easily removable. I know I don't want my keychain light sticking to everything else in my pockets. And I've never had the need to stick my light on anything yet. I'll stick with my ReVo for now.

+1. I love the idea of a magnet in the base but don't really think I'll use it in my keychain light since it's attached to my keys which are pretty heavy... at the same time, I'm a little worried about having a strong magnet in my pocket in terms of messing with credit cards and such.

I have kept hard drive magnets next to my credit cards biking to and from class with no problems. A hard drive magnet is much more powerful than this. The BEST way to erase magnetic media is a rapidly changing magnetic field - a magnetic eraser flips North/South quickly to scramble things. A magnet won't do that under normal conditions.

looks like a ~160° flood. perfect!!
i also like the green tint because it is a beautiful green and you cant decide if it's actually a blue tint and not the ... greenish tint of an xpg or xml.

i think the tint is called turquoise

WOW! That really is GREEN. For anyone who's seen it in real life, is it that bad? Or maybe it just looks that way on the video?
 
One thing to keep in mind, this is a flood light, so it will not seem as bright as a light with a reflector/hotspot.

Thank you for this... this makes it a little more tempting... I want to read reviews!
 
Your order has been updated to the following status.
New status: Shipped


​Woot!
 
I'm going to wait for the reviews. I don't think this will displace my SS ReVo, but it might make an awesome gift light (previously the itp A3 and now the Thrunite ti). Tad concerned about the runtime. Especially for a gift light to non flashaholics who don't carry backup lights or batteries.

Is it confirmed it is 1.5 hour hour runtime using Eneloops?
Click to expand...
no its not.
in the nutnfancy booth review David said something about "normal Alkalines" and "one humple triple A".

but let's get real. on an Enveloop runtimes wont be significantly higher. high performance Cree LED just drag any kind of cell to early :sick2:

great booth review btw, thanks nutnfancy!! ( is he a cpf member? )

Happy to see the moonlight and the runtime seems about right given the capacity of the AAA. Quite surprised at the runtime for the 25 lumen level though, that seems proportionately low compared to 4Seven's AAs and the Revo is supposed to do nearly 6 hrs on a AAA @ 19 lm. What gives?
 
In the vid David says it's underrated and does more like 30 otf lumens. Asperics is less efficient compared to a reflector for gathering the light from the led. In this case it's a flood tuned asperic so the lense is really close to the led. With a 130 degree beam angle on the led, im sure there are some lumens lost compared to a reflector. Even with the lense close to the led. Who knows the actual current draw?
 
Woot! mine shipped today! Can't wait.
Noticed today that my Preon 1 with clicked turned on in my pants, it'll be nice to edc something much smaller and a twisty so it wouldn't accidentally turn on.
 
Doesn't the Fenix E05 achieve 25+ lumens for nearly 3 hours on Eneloop? One of my favorite EDC lights.

Hoping for the same type of runtime on this light with rechargeables. An even wall of light is very useful and easy on the eyes for general EDC usage (for my needs, anyways) and the versatility of the super long running low could make this a winner.
 
In HKJ's review of the E05, he got about a full hour more of runtime out of the Eneloop vs. alkaline, so even at lower voltages the Eneloop still outperforms. My point is that there is still a high probability that the runtime numbers on the package of the Preon 0 are less than you'll get on a good nimh cell. According to this runtime test of the E05, he got 5-6 hours on a lithium primary, so there is hope for that as well.
 
Ok, the runtime charts on HKJ's review persuaded me to pre-oder :)

David says it's really 30 OTF. 30 for 1.5 hours is still pretty poor but HKJ's review shows the E05 adding 50% to the runtime when using eneloop over alkaline AA. This leads to an estimate of 2hrs 15mins with an eneloop on the P0. I'm guesssing the slight loss in lumens from the E05 is due to the lense type, the P0 doesn't look quite like traditional TIR and more like an aspheric type with semi-reflective GITD backing.

Still 30 OTF for 2hrs 15 isn't bad at all. I measured my iTP A3 (XP-E std ed.) at only 60 OTF in reality and that goes for 50 minutes. When considering the P0 uses XP-E not XP-G it seems also in line with the Fenix LD01 R4 which does 78 OTF for 45 mins or 30 OTF for around 3 hours as XP-G is around 50% more efficient than XP-E (at standard flux bins Q5 and R5). I'm assuming this uses XP-E R2/R3 depending on optical losses in the lense set-up according to these estimates.
