I bought one of these recently, but not before searching on it and finding lots of good information...all about a year old though. Seems like no one has been discussing this light lately, so I thought I'd share my impressions for anyone else who is looking at one.
I had an UltraFire WF-502B flashlight with an SST-50 LED and a single 18650 battery. The thing never worked right. I modified the switch many times (where the source of the problem was) but could never find a real solution. Finally I had enough and ordered a real bike light, the Gemini Titan.
The one I ordered is the older version with the P7 D-bin LED rated at 900 lumens, but some things have changed compared to the versions that were posted here earlier. Seems that Gemini listened to you guys about a few things, which I find pretty cool. I got mine on sale for about $85 shipped on ebay, I believe the seller is Action LED Lights although they go by a different name on ebay. Good seller, ordered late Thursday night and it arrived today through priority mail.
Gemini also has a new Titan with an XM-L LED unit which is supposedly even brighter than this one. There's also a new unit called the Xera which I don't know much about, but I think it has an XM-L and enhanced optics as well, but this review will focus on the P7 Titan.
Here's the box it came in:
The box is actually very nice, it's compartmentalized with foam inserts and has a magnetic seal lid, so it's reusable as a travel container if you ever need that.
It was advertised to be shipped with a 3-mode LED unit, battery pack and holder, charger, and o-rings to mount the unit onto the handlebars. Basically the standard Titan package. It actually came with a fair amount more than that though, mine came a 4-mode LED unit, a 1 meter extension cable to relocate the battery somewhere else, and two different choices of optics. I really thought the choice of optics was a great inclusion by the seller or the manufacturer that sets it apart from a stock Magicshine.
Mine shipped with both the flood optics (left) and the standard spot optics like most of these lights, including the MagicShine, ship with (right).
Here's the light head itself:
Nothing much to comment on here, other than it's very solid and slightly wider than a MagicShine unit but not as long. It does have a ring that glows in the dark though:
This is another improvement over the MS, these batteries are 5100 or 5200 mah vs. the MS which has a 4400 or 4500 mah rating. While not pictured here, they are double shrink wrapped for water protection. They are also apparently made by a known reputable manufacturer (BAK I believe?) who also supplies laptop batteries for Dell and HP so no worries about premature failures or hazardous cells. They provide a 4 hour runtime on high which has been confirmed both here and in other places in several threads so I won't test that for myself. Same for the charger which has also been tested previously and shown to be safe so I won't delve into that either (not like I know how)...
Time for output shots...
This is with the flood optics. I can't recall my camera settings although if I could find them if it's really important.
Exact same settings with the standard spot optics. I rode with a guy who has a P7 MS and the beam pattern looked just like this. I really like the flood optics, it gives a very wide beam pattern that's very usable. Good going on the manufacturer or seller for including this.
As far as brightness, the guy who has the MS in our group set his on high with the spot while I did the same with my flood optics and they were more or less equally as bright. That tells me (and confirms what others have found) that the Titan P7 is brighter than the MS P7. Both are rated at 900 lumens. I also found that the Titan has a much whiter light than the MS. For comparison, the Titan's color temperature looks more or less equivalent to that of a car with stock HID headlights, or about 4300k. When a car with HID's approached from behind I had trouble discerning the color difference. The MS appears to have a slightly greenish tint.
Compared to my SST-50 flashlight on high, there is absolutely no comparison...the P7 Gemini blows it away. Interesting because the seller of the SST-50 flashlight rated it at 1200 lumens. Bit of an exaggeration, probably.
As I said earlier, my particular Titan has four modes...low, medium, and high...press and hold the button for 2 seconds and it will switch to a slow flash (once every half second, which I find more useful than a strobe), hold it for three and it will turn off.
I suspect I got mine on sale (they're supposed to retail anywhere from $110-$130 with extras) because it's the old model and the new XM-L is the thing in LEDs I suppose. But I can't see myself outrunning this light in any situation, and I ride on some very dark roads.
All in all, really good buy for the money though, I think. I was originally going to get a MS but in the end I'm glad I got this instead for the better batteries, color temp, and choice of optics.
