Eight positions with a single turn

The filters are built into the flash head. Turn the wheel to switch colours instantly, with no need to find a gel, cut it and tape it to the head. Seven colour filters are available, plus a clear position for neutral light.

Seven colour moods on a single wheel

Filters #85CTO and #82CTB correct colour temperature towards warm and cool, while #206, #812, #102, #805 and #504 are effect colours for portrait and product photography. Switching takes a second, so you can try variations right in the middle of a shoot.

No gels, holders or mess

Traditional colour filters are bulky, hard to store and easy to lose. The KL01 has its filters built into the head, so you just turn: fast, clean and effortless.

Four power levels

Use the M button to switch power between 1/1, 1/2, 1/4 and 1/8. Lower power means shorter recharge times and longer battery life, ideal for fill light. At 1/8 the flash handles a continuous burst, and at full power it recharges in 2.5 s.

Up to 600 flashes per charge

The built-in 3.8 V / 400 mAh battery lasts up to 600 flashes at full power. It charges over USB-C in about 1.5 hours, with the same cable as a phone. The charging cable is not included.

Controls at a glance

On the body you find the power and output button, the test flash button, the flash window, the colour filter wheel, the power level and charging indicators, the USB-C port and the hot shoe foot.

Fits in your pocket

The flash measures 53.5 × 43 × 37 mm and weighs 49 g. Carry it in a jacket pocket or a side compartment of your bag and attach it when needed. The single-pin hot shoe fits most digital cameras with a centre contact, and the flash works in manual mode.

Portrait and creative photography

Colour filters change the mood of a shot, from a warm evening portrait to a rich fashion frame. Actual flash output varies with the selected filter, as each one transmits a different amount of light.
