The compact, lightweight FlashQ Q20II from LightPix Labs is a cost-efficient, manual-exposure lighting solution with advanced triggering and control features. The flash weighs just 4 oz and measures 3.9 x 2.3 a 1.1", making it easy to squeeze into tight places where larger units can't go. With a guide number of 65, the Q20II has manual power selection from 1/64 to full power, runs on two alkaline or rechargeable Ni-MH batteries, and will recycle to full power in 6 to 7 seconds depending on the batteries in use. One of the flash's clever features is the RF transmitter built into its removable foot and the receiver built into the body of the unit. By detaching the transmitter and mounting the flash head remotely on a light stand, you can adjust power and trigger it from the on-camera transmitter at distances up to 33'. In fact, the transmitter can control up to eight Q20IIs simultaneously. Convenience features include a flash head with a built-in filter holder and tilting capability in 0, 45, 60, 75, and 90-degree click stops. Finally, a pleasant surprise is the Q20II's LED light which can be used as a modeling light, or with its high CRI of 95, used as a 5600K video light.
