We here at PIXAPRO offer a varied selection of lighting for your needs. Two of our flash lighting units that we have available are the LUMI400 and the STORM 400. In this blog, we will look at the specifications of both of these lights and advise you on which would be best for your requirements.

Whilst these two lights share quite a few similarities, they are a few rather important differences between the two. The power range for these lights differ quite a lot, as the LUMI400 comes with a 6-stop power range that is between 1/1 – 1/32 power, whereas the STORM 400 has an 8-stop power range that is between 1/1 – 1/128 power. This allows the STORM 400 to make much more accurate adjustments in power, whilst also having a much wider power range to work with, offering the user much more flexibility. The Recycle time for the STORM 400 is also a much quicker range, as it is from 0.05 – 0.7s, compared to the recycling time of the LUMI400 which is 0.3 – 1.5s.

The LUMI400 also misses out on many features that the STORM 400 comes equipped with. It comes with Rear-Curtain Sync, which is when the flash fires at the end of the exposure, or at the rear curtain, allowing you to freeze the subject at the end of the motion blur trail. As well as this, it also comes with High-Speed Sync which enables you to use your flash at shutter-speeds faster than your camera’s sync speed without having to worry about a black bar across your shot. One of the more impressive features that the STORM 400 has is called “Stroboscopic Flash Mode”, and what this feature does is causes your STORM 400 to fire multiple low-powered flashes in rapid succession. Combined with a slow shutter speed, you are able to capture a sequence of images of a moving subject in one exposure such as the one in the photo above.

These features effect the purpose of each of these lights. The LUMI400 is a powerful flash that has many uses, such as for still photography and portrait photography (ranging from a single person to a group shot). The STORM 400 however is a more specialised flash. Whilst it can still do all of the things that the LUMI400 can, it is also possible to be used to capture motion very well such as sporting and dancing, this is something that the LUMI400 isn’t designed for.

So, if you are looking for an easy to use, high quality, powerful flash unit, then the LUMI400 will meet your needs. But if you are interested in a flash that offers more accurate specifications and many more features, such as High-Speed Sync and Stroboscopic Flash Mode, then the STORM 400 is the right option for you.
