Pros: - Very nice color, especially outdoors.

- Brighter than my previous ones, quite possibly a brightness bin upgrade.

- Aluminum pill with brass ring for pcb improves heat transfer from the led to the module.

- Single mode, perfect with a forward clicky.

Cons: - Warm white leds can become an addiction, you are warned! : )

Other Thoughts: Works well on 1-2 Li-ion or 1-3 CR123A.

If you have never tried warm white leds before, this is a cheap and good way to try it.

Bottomline: Get one and try it, you won't regret it.

Great drop in with 5A tint

Pros: Great tint for outside use. As another user has already pointed out, when you go to a 'warm' tint like this, it is hard to ever go back to the cold whites. Yes the Q5's and R2's of this world put out more lumens per watt, but many of those lumans are at such a high colour temperature that it really doesn't contribute much unless you only plan on shining your flashlight at white walls all the time.
 
Cons: This is only a single mode emitter. When, oh when, will the driver manufacturers start making simple three mode (High, Medium & Low) drivers for these things.
 
Other Thoughts: This drop-in will work from a single 3.7v cell but the output is reduced slightly.
I have noticed minor flickering for a short time after switch-on, occasionally when running on a single 3.7v cell. Maximum brightness is acheived with a supply voltage of at least 4.5V. Works fine on 12-14V as well (for anyone thinking of running these from a vehicle supply. Current draw at 12v is around 330Ma. I like to turn these into compact throwers by replacing the stock OP reflector with a smooth one from an sku.5937. This setup works very well in one of my favourite hosts the WF-502B.
 
Bottomline: Nice drop-in.
Can't wait for this tint emitter to be producing >100 lumens per watt.
I live in hope!

Once you try it, you will never go back.

Overall Rating:

Pros: -Neutral white 5A bin emitter
-Excellent color rendition outdoors compared to common cool white LEDs
-A quite respectable output: 185 lumen out of the front (measured in a Surefire 9P on 2 li-ion cells).
-decent beam without very pronounced rings
-fits somewhat tightly in a Surefire which means better thermal path than with loose fitting modules
 
Cons: -The head does not screw all the way down, leaving a 2mm gap (a cosmetic issue, really).
 
Other Thoughts: Warning: once you experience neutral white emitters once, you will never go back to cool white.
 
Bottomline: Get it. Now.
 
					

Good, cheap, warm

Overall Rating:

Pros: 5A tint is very pleasant without looking "sickly yellow"
Good throw
Relatively clean beam
Works well on 1 or 2 Li-Ions
Single mode (some people may consider the lack of low modes as a con but I love single mode, especially with a forward clicky)
 
Cons: Q3 would be a nice upgrade and is available in 5A tint
Output is not as high as other modules but still very good
 
Other Thoughts:  
Bottomline: Great module that is easy on the eyes, especially useful outdoors where the warm tint and good throw are put to good use.  Makes a great addition to any P60 host.
