I have a Q5 mod in a my Key Chain CR2 host that is a 'must see' as well:
http://laserpointerforums.com/f57/q5-mod-key-chain-cr2-very-nice-44067.html
Key Chain 10280 mod...
This time, I disabled the little circuit at the button switch, and used a 3 ohm 1 watt resistor to regulate the current to 332mAs'!
(With a 3.6 volt rechargeable, the emitter will draw 1 watt without the resistor)
This seems about 3 or 4 times brighter that my first Key Chain flashlight mod seen here:
http://laserpointerforums.com/laser_pointer_forums_3/forum/showthread.php?t=34357
With this one, the 'constant on' feature is disabled. The side button is a momentary switch now, which is fine. The run time is going to be less than an hour between charges with this brighter version.
Note: For a 'push on - push off' switch with this higher current, see the pictures below the 'beam shot' under 'Retrofit'.
Using the 'Task Force' key chain light from Lowe's, and the emitter from the 'Pocket Mini Host'
* Key Chain light: http://www.lowes.com/lowes/lkn?action=productDetail&productId=225284-50584-FT-MINI&lpage=none
* Pocket Mini Host: DealExtreme: $13.75 Ultrafire WF-602D 3.6V Cree Flashlight (CR123A)
* Or you can buy an emitter by itself, such as this: DealExtreme: $5.36 Cree XR-E Q5 Emitter on Premium Star (228LM at 1A)
* 10280 batteries: AW's LiIon Batteries Sales Thread *Part 8* - CPFMarketPlace
* This charger works well for these batteries: Battery chargers for lithium ion coin cells
Here are the pictures...
It has no reflector except for the shape of the key chain head...
Update: Reflector and glass lens retrofit! (see below)
The throw is very wide, which is really nice for a light of this size... *
Not a bad use for the left over emitter from the Pocket Mini Kit!

Retrofit! - Now a 'push on / push off' clicky installed under the side button!
Using a clicky switch similar to this one from DX: DealExtreme: $1.80 Clicky Switch for Flashlights (11.8mm 5-Pack)
(only mine has one leg at one side and the two alternating hot legs at the other side - see pictures)
Here's how...
It was a lot of work to get the clicky to fit inside. But now that it is all done, I am very happy to have it working at this higher current using a clicky (constant on) switch! *
Using the clicky switch, and 3 ohm 1 watt resistor, I measure 332mA's current draw with a fresh battery!
Reflector retrofit!
Man! I'm really happy with being able to fit the head of the tiny Key chain light with a machined down reflector from the Pocket Mini host, and an 11mm X 1mm thick piece of flat glass. (this is the modified lens from the Pocket Mini host, modified using a sand blaster)
This little guy has some throw now! Nice center spot too! Not bad for the size of it!...
Another cool mod for this great Key Chain host! *
This time it is using a huge, super bright 'Blue' LED with a very narrow beam (10 degree), and a 10280 battery...
The wall in the beam shot is 30' away! This sucker is so bright that it just about has a beam at night! If the beam was any narrower, it would be a 473nm laser!
