Still, a Quark Mini 123 is amazingly close, with 1/6th the battery and 1/100th the size.
Quark Mini 123 with RCR123 on high is rediculously bright, and surprisingly close in brightness to the RL-2088, at least in percieved brightness at certain ranges. However, over distance, the RL-2088 pulls ahead.So how close is the quark when you have the Ultrafire on high?
