Epos 300
13.1 Bowens mount
The Epos 300 is a Bowens mount compatible light, this means that in theory every off-the-shelf Bowens mount
accessories like modifier, optics, fresnels, etc. should fit. However, due to there not being any standard on the
depth or shape of lights, we have chosen to create a list of modifiers that we have tried and approved for use with
an Epos 300. There might also be many more that works fine as well. We have also designed several different
diffusers for the Epos 300, so that it is possible to fine tune the quality of light when using it in combination with
other modifiers. The recommended diffusion is listed with each modifier.

13.2 Kelvin modifiers
The difference in output between the different diffusers is minimal; 00 is a 0% light loss, 90 is around 0.1 of a stop
and 75 is around 0.1 of a stop again.
Diffuser D100, has 0 light loss and is best for when you need the hardest light source possible, this works very well
alone or with other accessories, but you might find some color fringing on the edges when using third party
accessories.
Diffuser D90 has a light loss of 0.1 stop compared to the D100, this diffuser mixes the colors a little more to allow
for no color fringing when used with more advanced accessories
Diffuser D75 has a light loss of 0.1 stops compared to the D90, this diffuser is great for use with Softboxes or other
accessories which require a wider beam off light.
Dome Diffuser is the perfect diffuser for use with an octadome or other softboxes where you want the softest light
possible, and also the perfect match for umbrellas or parabolic light modifiers
.
13.3 Other modifiers
The Epos 300 will work with most off-the-shelf Bowens mount accessories like modifier, optic
s, fresnel’s, etc., and
the choice of diffusion will be defined by how much of the silver you use. The D100 filling the least and the D75
filling the most, we have also created a dome diffuser which allows for a much wider and truer to traditional
softbox/tungsten bulb type quality of light when working with softboxes, umbrellas and so on.
