note: For the full output range, the HC33 requires an 18650 battery with >8A output. The HC33 can also be powered by normal 18650 batteries, 2x CR123 or 2x RCR123 batteries in a pinch. However, the light might shut off at the Turbo or high setting when using CR123As or 18650s with lower than 8A output.
