I picked up a Surefire G2L (L = LED) a couple of weeks ago, figured I'd give it a little once over for you guys.

The Surefire G2L is rated at 80 lumens, with 11 hours of output. Before everyone jumps down my throat about this, no, that's not 11 hours of 80 lumens. It's a decreasing curve of regulated light, hard to explain but I try. Someone will jump in with a CPF graph sooner or later. Going price is about $69.

The light is a bit shorter then a AA Maglight, and a little bit wider as well. It runs off of 2 CR123 3V Lithium batteries. These used to be pretty expensive, but buying in bulk or direct from Surefire will lower the cost a good amount.

Completely Made in America, the light has an aluminum bezel (acts as a heatsink) and a polymer (Nitrolon) body and tail cap. The tailcap is the push for momentary, twist for constant type. It's useful but it does have it's limitations. You do have to twist for constant on, and sometimes pressing the tailcap (not the button) down will activate the light. Another $50 will buy you a "clicky" tailcap, but for that additional price you might as well get either a E2DL or another G2L.

The beam pattern was typical Surefire. Flawless bright center dot with an even diffused surrounding off spill. Light color was a different story. Close up you can't really tell, but turn the lights off and shine it on a white wall and there is a very noticeable blue ting to the light. Disappointing really considering my E2DL has a perfectly tuned white beam.

Run time was pretty accurate. After about 8 hours you notice a large drop in light output, and it slowly goes down to nothing after about 20. At 10 hours I could still find my way in the woods, and at 15 I could still light up the inside of my car reasonably.

Construction was top notch, F&F were amazing as always. Close tolerances on all the parts, especially the battery tube. Changing batteries is fun because they slide in without any rattle and hold very securely. Some lights will have a battery "rattle" while this one doesn't.

This is an excellent backup or emergency light, as well as a great light for what I do (construction/mechanical contracting) because you're always either using it or loaning it out. With the polymer body I'm not worried about it breaking. Easy enough to wash up after exposure to unhealthy amounts of cleaning chemicals too. :thumbup:

Downsides include the beam color and tail cap. Upsides are relatively low price for a 80 lumen/2 CR123 battery light, outstanding warrenty, and great construction.
 
Excellent review!

The 11 hours is quoted as "usable light"... the 6PL has a flatter runtime curve because of the all-aluminum construction [better heatsink].

The blue tint is normal for the underdriven Seoul emitter that Surefire uses for this model.
 
Hey Josh. Good review. I too just got a new G2L. Mine had a 200+ lumen upgrade. If you unscrew the tailcap just a little more the button will engage fine but it won't be able to be turned on by just applying pressure to the tailcap itself. I actually prefer the momentary to the clicky caps. I like the polymer body as well. I hear they are easier to use in cold weather cause they don't get as bitter cold as the 6PL in the hand. Dang good little light for the money.

Be carefull with that G2L, with that much output you will have lots of heat build-up and could ruin the drop-in.

Nice review Josh, now you just need a malkoff. :D

I put a malkoff M60LL in my G2L and IMO its what the surefire drop-in should have been. With the malkoff you get a true 8 hours of regulation better tint and a better beam. Like the surefire drop-in you can also use 3.7v RCR123's to power it for free lumens, you also get a bit more throw with the malkoff because of the optic.

The only down side to the malkoff is you will have a slight gap in the head area but this does not effect anything its just cosmetic.

Here is a side by side of the two drop-in's, surefire on the left malkoff on the right.

I guess that explains it.

I dabbled in hobby electronics for a couple of years, so I know a wee bit about this, but not nearly as much as some of the CPF regulars do. Underdriving a LED will give you better efficiency, I just didn't know they did that on the G2L.

The P60L also has a thermal regulator that cuts down the power when the heat builds so it does not destroy itself. 80lm becomes 65-70 in a very short time with the G2L.

Because the G2L now uses a Aluminum head, would that still harm the following dropins?

I run my E2DL till it hits about ~15 lumens then I swap the batteries.

Mostly I do contracting work, and everyone needs a flashlight. Some people pull out little AA lights and squint, I pull out my E2DL (high mode) and hand it to them. The difference is night and day.

Of course, then they ask me how much it costs. :rolleyes: $150 is unreasonable to a lot of people. I got the G2L so I have a easy to spot (yellow), very durable, above average light that I can honestly recommend to other people on the job site.

Browsing the Surefire site I just noticed that they also have an upscale G2L with some reflective tape and a diffuser.

The M60L and LL are the best options the M60 could be used for a few minutes at a time but not for long periods, the M60 MC-E is not even a option the amount of heat that thing kicks off might melt the light.:eek::D

The change to the aluminum head helped but it does not do that much, the malkoff module though is almost a perfect heatsink itself. Besides being a heavy solid chunk of brass its back filled with thermal epoxy even sealing the driver board. I like the LL in my G2 but have been wanting to upgrade to the L. I switch to using my G2 in the winter time because metal lights get to cold, the 80 lumen LL gets the job done but my current work light is 600+ lumens so switching to 80 in the winter just dosen't seem right. :D

Where did you find that surefire that thing is sweet?
 
Hell yeah, I see surefire is finally putting up real runtimes.
