Zebralight SC600 Mk II L2 (XM-L2, 1x18650)

Hey commuters: I have been seeking the holy grail of lights. I am sure many of you have as well. I recently found on the Candlepowerforums a great little self contained super bright and not too expensive light. It is a Zebralight SC600 MKIIL2. I believe there are 3 models: the SC600, SC600II(L1???) and SC600 MKII L2. The main difference between the SC600 II and SC600 II MK-L2 is size and brightness. The MK L2 cost around $95, the other is between $65-75. The SC600 is no longer for sale and the SC600 II is being phased out.

Zebralight SC600 MKIIL2: 1100 lumen, 2 hrs. runtime, 4 in(101mm) long, 1 in.(25mm) wide, 78grams(w/out bat), single 18650 battery, beam is 80 degree spill, 10 degree hot spot, waterproof. I am seeking step-down info from CPF. If it is only temp driven this may be the real deal. Easy to pocket it when shopping, last really long for a single battery.

Here is their review:

That's a heck of a review. I see 8 very favorable reviews for it on Amazon, too.

Be careful where you aim it!

[MENTION=191215]balto[/MENTION].....I read over that review. Sounds like these are the "gold standard" when it comes to torches. I would love to own one of these but all things considered I only use torches now for back up and the ones I have work very well as bike lights. Still, if I could afford to drop $90 and not worry about it I would. Always nice if you can afford the best.

If I were one of those people in the market for a single emitter self-contained light for the bars I would definitely consider one of these rather than one of the usual bike light company offerings.

I just read some more recent comments on the CPF. Here's a quote. "....the thermal regulation is just fantastic on these new zebralights! since cooling is good it doesn't throttle down very much....."

Most high powered LEDs have a timer step down. If your light is 800 lumen it will drop down to 600 lumen after a certain time. 5 minutes seems to be a common time. The Zebra is temp driven so if you are cycling(essentially cooling the LED) this light will not drop down. You will keep the 1000 lumen.
I notice on my Magic shine and cheap chinese Cree knock-offs that this is the case. I lose lumens in a short period of time, even if the air temps are freezing. I do not know if this happens to all lights. I know bike specific lights seems to have good cooling 'fins' on theirs whereas flashlights do not. So maybe this does not happen to some bike light models.

@01 CAt: It is pricey, thus I am slow to move on it. If I didn't have lights I would buy it. For a self contained light I see nothing that beats it ....for now Plus it is so small, fits easily in pocket or mounted to a helmet.

Yes, the thermal regulation is intriguing and clever. balto, thanks for explaining why my 18650 flashlights go dim so quickly. Or maybe that's not why. They last a disappointingly short time. I've found them pretty unsuitable for cycling.

The cooling regulation is intriguing. Several things make this torch a real "want'a have"; The UI for one. The choice of power levels is almost perfect. I say "almost" because it does require that you memorize all the different "flash sequencing" to set the modes the way you want. A simple "*step-less UI would of been preferable ( * UI where you get a choice of ten levels for each mode like with the Gemini lamps )

The reflector used on these look real interesting. I can tell just by looking at the photos that the beam pattern will likely have a nice mix of spill and throw. Add to this that this is the first torch I've seen so far using a cool white version of the XM-L2 emitter. I've seen beam shots of the Zebralight torches before. They always look very bright with a nice smooth beam pattern.

Lately I've been searching for a new torch that has the newer XM-L2's, preferably with a cooler bin like U2. I also would love one with a "Step-less" UI but so far this offering from Zebralight comes closest to what I have been searching for. Jeez, you have to love the size of these things as they are so small!

My current set-ups use just three modes, ( H-, full power, M- about 275 lm, Low- about 110 lm ) no flash. I do have an XM-L2 drop-in that is neutral white and that one is perhaps a bit brighter than the others I have. Nice thing about the ZL MK II is that it has a 350 lumen mode setting. That setting would be perfect for all-around bike riding when used on the bars. At that setting you should get over two hours with one good Panasonic cell.

This the first year in a long time where I "did not buy" myself a lighting product for Christmas. Only reason for that was lack of funds. That said the credit card trigger finger is getting real twitchy. It's going to be real hard for me "not to buy" one of these MK II's. ( being the LED torch, bike light junkie that I am )
