Commonly asked questions about the Splash A-Lux Mono Range and Panel Flash:


Hi Pete,
I received my A-Lux today and have to say I am very impressed I will will have a good play over the weekend.
My only very small criticism would be the manual I think it would be better just on line and maybe us a video or photos.
But mate its a great light
Cheers for all you help.
(Come-on, UK A-lux purchasers, lets have some feedback!)
Hello John, 
You are right, the instructions are brief; we were meant to include further instructions and specifications on the website. This will be done shortly.
The A(automatic) mode is for use with another flash that has pre-flash eg speedlite on shutter/aperture/program priority. The A-Lux M252/302 produces its own pre-flash in response so that the camera can read the A-Lux flash as well as the speedlight flash (and ambient). If the speedlite is on-camera, then adjusting the speedlight’s EV from the camera position will adjust the total light that the camera receives including the A-Lux light


Hi Peter,
I received the flash some weeks ago, and I'm thrilled with it - its not often that I find myself saying "that's cleverly done" when it comes to equipment. I'll be planning for my next purchase soon after I work this flash into my work flow.
I have just a few minor gripes about the lack of documentation though - e.g. the A mode - how it is supposed to work, etc. I wonder if you have a writeup somewhere or if you are planning to post more about this feature on the web...
best regards
From gentleness comes strength. From stillness, wisdom.

Hi Pete,

'Your new picture on the home page, how was it taken?'


The child was taken in a friend's lounge using the excellent Lastolite HiLite background with a Mono M302 inside with a reflector, the new Magneflash Strip Light vertically to the left and a P102S Panel Flash on the floor as a chin light. Daylight from a window on the child's left supplied a relatively small amount of light, as can be seen. All units were on automatic with the Mono and Strip being at minimum power. The dslr camera was on shutter priority 1/100th and hand held with a speedlight on auto 1/16th power. This triggered the whole setup and the photographer was free to 'catch' the moment as the child moved around (they never stay still!). All units were on battery power so there were no cables for anyone to trip over.

A small amount of contrast change and the child's runny nose were 'Photoshopped'. About 70 pictures were taken of the family, dog. cat et al with plenty left in the batteries afterwards. It was a case of the photographer coming to the home rather than the subjects going to a studio, but the Magneflash units still delivered studio quality results.


Hi Pete,

'Your 'Smarties' pic with the Panel Flash; why not just use a speedlight?'


The image requires the combination of the right amount of light, a short flash duration, a relatively large light source for the soft shadow and accurate colour. It would be a challenge to do this with a speedlight. The P102S Panel flash has a similar amount of power as a mid-range speedlight. You would need a top-end speedlight working at half power or less to give the short flash duration. You would then have to use it with a diffuser or bounce (to get the soft shadow) where there would be the loss of another stop or more of light. You would then have to colour correct the blue/gray caste most speedlights would give at this level.

The image really needs two light sources, a main and a key. The easiest way to do this is to have a speedlight on camera pointing up at the ceiling (or diffused) as the main light and the Panel as the key light. If both are on TTL automatic and the camera on shutter priority, it is even easier providing the 1/10th sec or so pre-flash delay is compensated for.

In the same way as the Panel, a M302/402 series Mono, with a key light reflector fitted, would do a similar job but at a much higher light level.


Hi Pete,

1) 'Can the Splash Panel flash use rechargeable AA batteries instead of alkaline? How many shots would they give?'

2) 'Can the Panel trigger from a 'phone camera flash?'

3) 'In what circumstances would you use an umbrella with the Panel flash?'


Yes, two AA rechargeable cells can be used, preferably NiMH type with at least 2000mA capacity for 100+ shots.  If using alkalines, good quality batteries will also give 100+ shots. The Panel flash can be left switched on for several hours though this will impact the number of flashes available.

Yes, the Panel can trigger from most 'phone cameras provided their flash is true Zenon rather than just LED.

The Splash P102S Panel flash can be used with an umbrella (up to 100cm size) providing close-up, ultra-soft lighting mostly for head & shoulder portrait photography etc.


Hi Pete,

'Do I need two Panel flashes with my medium size product photography light tent, or will one be sufficient?'


When using an on-camera speedlight to trigger the Panel flash in auto mode (ie total two light sources), usually one Panel flash at the back of the light tent will be sufficient, though a lot will depend on the type and size of your subject. Two Panel flash units will give greater light control particularly if they are used in manual mode with the camera on manual, though they can both be used in auto with your speedlight for a three light-source set-up.


Hi Pete,

‘Are the Splash A-Lux Monos camera-specific, or will they work with any camera?’


‘The Splash Monos will work with almost any camera. The Mono flash units can be used with cameras with hot-shoes via the sync cable provided (you will need a straightforward hot-shoe adapter to fit your camera – available from your local store). Cameras that don’t have hot-shoes but have a built-in flash, including compact cameras, can be used. The Splash units recognise and respond automatically to the pre-flash that these cameras usually have. Some cameras switch between one or two pre-flashes; the Monos will respond accordingly, producing a flash each time to fix the camera settings.

The Mono flash units will also work automatically with speedlights – shutter priority is a good setting to use.

They will also work with standard studio lights.’



Hi Pete,

‘My speedlight has a higher guide number than the Splash Monos – do the flashguns have more power?’


‘The Splash A-Lux Monos, in common with most studio flash units, have their light outputs measured with a 50degree reflector. Speedlight guide numbers are quoted at 50mm focal lengths or higher. These give more on-axis light but, generally, when the flashguns are made to give wider light spread, on-axis light is reduced. Speedlights/flashguns are not efficient when used with larger umbrellas since they struggle to fill the umbrella with light and so produce a smaller light area.’


Hi Pete,

‘Can I use radio triggers with the Splash/A-Lux Monos?’


‘Yes, most wireless triggers can be used with the Monos (3.55mm jack plug connection – the sync lead supplied with the Monos can be split to allow the trigger to be connected remotely). The best triggers use the universal 2.4GHz frequency.


Hi Pete,

‘What are the w-s (joules) ratings of the Splash Monos?’


‘The Monos, as with speedlights, are not specified in terms of watt-seconds or joules. However, the light-output of the M302s can equate to conventional studio flash powers of up to 120ws at slow shutter speeds or up to 240ws at shutter speeds 1/500th sec or shorter. The M402s are 200ws and 400ws respectively.’
