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:
