Introduction

Epos 300
The Kelvin Epos 300 is an RGBACL LED COB studio light with full color soectrum for professional use in the film industry. The lighting technology developed by Rift Laos enables especially high accuracy and quality of the light emitted across the full color spectrum, giving the users a much more predictable and continuous quality in their creative use. The technology is combined with high attention to user and customer experience in usability and digital/physical UX, exceeding market standards. It is designed and constructed for longevity in a rough working environment. Made to withstand life on set and beyond.
2.1 Features
The Kelvin Epos 300 provides lighting to professionals with a minimal environmental footprint. All lamps are LED-based, ensuring a low and efficient power consumption, with maximum light output per watt. Most of the casing assembly is made from highly recyclable materials. A reliable and lasting quality gives the product a much more sustainable footprint. Combined with high efficiency and sustainable solutions in manufacturing, logistics, and packaging, the Kelvin Epos 300 is a high-performance product made in Norway.
2.2 Properties
Due to the unique Cantastoria Light Engine, a predictable continuity of lignt across the full color spectrum is guaranteed, and the light intensity is highly precise and controllable to an accuracy of 0.01%. The light and build quality exceed industry standards and solves a major challenge of life on set: It is durable, sturdy, yet compact. The materials make it sturdy; the design and the construction make it strong. And the form ts not just beautiful, but allows the light to be stored vertically, horizontally or in any way needed, without endangering the elaborate electronics within. We believe The Epos 300 has any expectations in its segment. We further aim to elevate industrial design standards and attention to detail in the film light industry, with a design conveying the main values of Kelvin – precision, sturdiness, usability, and accessibility.
2.3 Idea
To creators, cinematographers, photographers, studios, and filmmakers, light is essential to define and set the ambiance for a set scene. It makes the difference between a good story and great visual storytelling. In addition to providing a high-quality light, smooth usability is core to be efficient and making the best use of valuable time on set. The Epos 300 is designed to address usability and efficiency in use, providing a fully compatible app for iOS and Android – Kelvin Narrator – to control the lighting unit via Bluetooth, in addition to its touch screen and buttons. Seamless integration of a full lighting kit on set is possible, whether controlled with a touch of a finger on a phone or the individual control units of the lights. Equally, reliability and power requirements are key factors addressed through dedicated design and engineering.
2.4 Form
Electronics and lamps are delicate components requiring sturdy casing to prevent damage from impacts caused by drops, rough use, exposure of weather and rough conditions. The design of the Epos 300 is developed to communicate the impact of a high-tech precision device, while being robust, reliable, and practical. An innate simplicity also reflects the efficiency of a modular production, smart logistics and the ability to be recycled. Extended use of aluminium allows a sturdy construction, which is also easy to recycle, long lasting and a superior protective case for its sensitive electronics within.
2.5 Function
One of the benefits that advocate the Epos 300 is the separation of the light head and the light control unit. The light may be controlled remotely from the Bluetooth, Kelvin Narrator App for iOS/Android, DMX, Lumen Radio/Wireless DMX (built-in) or from the separate control unit, which is operable free standing or suspended from a vertical support. The light unit can thus be fixed remotely and in out of reach positions. The front of the lamp has a Bowens mount for various accessories that modify the light.

13.0 Approved Accessories
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; OO 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 O 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 D9O 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, optics, 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 D/5 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 wnen working with softboxes, umbrellas and so on.
