Ok, we found out that the KL5 can now handle 3 cells, 9 volts. Three CR123s, two 17500 LiIon, or other LiIon X2. How about the KL4? Did Surefire change the circuit on the KL4, also? I inadvertantly put in two RCR123's in my L4 today, and it worked fine, though it did scare me when I noticed the switch. The RCR123 cells were not charged up to capacity, and the KL4 circuit was pulling 660mA's from the cells. Has anyone run their KL4 with 9 volts, and what was the result. We need a brave soul to try this out.
