The most beautiful lightning flashes I have ever made! It was definitely the right decision to do this with the LFX Master DMX.
I will definitely pack the LFX Master DMX as standard equipment for feature films, as I have often had problems with the built-in effects from various manufacturers.
We had 1 x Arrimax 18K and 2x M40 with corresponding dimmer shutters. The shutter control, the lightning LFX, works really well with the “welding” effect of the LFX Master DMX.
Thank you for your world class support.

LFX Master DMX is like the name states – a masterpiece! This unique tool gives endless possibilities how to use your lights in practical way. Best example how powerful LFX Master is when people have asked me on set ‘where did you find this perfectly flickering fluorescent?’. I didn’t, the answer relies in LFX Master DMX. When coupled with wireless control trough iPad, you can adjust all your effects on the go and still keep the possibility to fine tune the colour of your LED unit. LFX Master DMX is always in my kit now-days!

Finally! After using the modular Flicker box for many years and more recent the universal flicker boxes LFX Master DMX and LFX Master dim there is a good solution to easy generate effects for your LED fixtures. Especially the function of DMX in is very useful. You can control (and even store) your effects in Luminair. We can play off set and have everything ready on set. That gives us the efficiency we like. Thanks!

Hello FXhub is a perfect tool for simulations of fires, candles and TV. We specifically we are using now in a movie about the bombing of Gernika, we have many days outside at night to recreate the fire following the bombing. We have come to set explosions to light, and we are trying to make fireworks effects. Very good buy.

As gaffer I have the luck/misfortune to work with some talented DOPs who work with a rich image. They are pushing the limit every time, they have an idea and I can find the solution. The LFXHub & RC4 were good compagnions to fullfill their desires: neon effect, broken fluoro, flicker effect wired & unwired, aeroplane position lamps, bad working headlamp, television effect with or without shifting colors.
