Colour temperature:
Setting 1 = 5090K
Setting 2 = 4915K
Setting 3 = 4915K
Setting 4 = 5000K

Therefore, total possible variation from different flash heads set to different power levels cannot exceed 4000 K,which is insignificant.
Variation between flashes at any given power setting is too small to measure.

Power setting dial:
Setting 1 = 1/32nd power
Setting 1.5 = 1/16th power
Setting 2 = 1/8th power
Setting 3 = 1/4 power
Setting 3.5 = 1/2 power
Setting 4 = Full power

Power adjustment is in 1/10th stop increments, and can be adjusted both by means of the adjustment dial and via the Wavesync Commander.

Please note that the Wavesync Commanderis supplied separately.


The SmartFlash 3 has a built in slave cell, located at the rear top, where it reacts to a flash from any other flash head or flashgun, and fires the flash if required.

The Slave Cell can be set to either S1 or S2, or can be switched off if required.

When set to S1, the flash will fire in response to every flash that it sees

When set to S2, the flash will ignore a pre-flash, which typically occurs when using a built in camera flashgun or a hotshoe flashgun that fires a pre-flash, for example when the flashgun is using an intelligent metering system.


The Flash Tube has an expected lifespan of 100,000 flashes and replacements simply plug in, there is no need to return the unit to us for a replacement flash tube.


The SmartFlash 3 accepts a standard Edison Screw (E27) replacement modelling lamp, and its 150 watts of power is ideal for all types of studio photography.


The Swivel/Tilt adjustment is simple and positive, and allows the head to be fully tilted.


The SmartFlash 3 accepts all S-fit accessories and light shapers, and the accessory release is made from steel, it is located at the side of the flash head.


The Stand mount accepts the standard 16mm / 5/8" fitting, used by all lighting stands.
