Designed around the latest-generation Osram 1400-PS Lok-it lamp, this now “classic” fixture is positioned at the top of the Claypaky range of traditional spots, delivering a powerful, uniform beam, beautiful saturated and pastel colors and a comprehensive set of effects.
We decided to scrutinize all the functions of one of these new fixtures in our own laboratory. We choose to test the Scenius Spot in Dimatec’s showroom, assisted by Rémi Derruau, product specialist for this Clayppaky
aky distributor.
Aesthetically, Scenius is different from its companion products, Mythos and Super Sharpy. The nose is squared but the more elongated head gives it a less stocky global shape. The lamp around which the Scenius was designed is the 1400-PS Lok-it, which has some very precious qualities: a color rendering index (CRI) of 95 and a luminous flux 20 to 30% higher than the lamp that powered the Alpha 1500 range.
The grand tour inside
Under the hood, the maintenance levels are well defined :
Level 1, , for anyone, anywhere, involves everything that can be removed with a Phillips-head screwdriver.
Level niveau 2 requires a higher level of skill and access preferably in the shop, using a Torx screwdriver.
Level 3, final level is reserved for authorized, Claypaky service technicians and requires a smaller Torx screwdriver.
We begin the disassembly and the guided tour.
The menu display and connectors are on the same side. There are the usual two XLR5 DMX connectors, one EtherCON connector for control via Art-Net, and one PowerCon True 1 chassis plug for mains power. As usual in a Claypaky fixture, you can access the menu to change settings or update the firmware even if the projector is not connected (small rechargeable battery inside for this use).
The tour of the exterior ends with the head, where two covers held on by four 1/4-turn screws don’t stand up very long to our curiosity. The two filters of the head are directly fixed to these two composite supports. This choice may seem a little odd, but we quickly understand that this places them above the fans while providing simplified access for maintenance.
The two large fans are mounted upside-down, in order to create an air flow on the components nearest the lamp. On the top and bottom of the head are the three control boards for the stepper motors and parameters. These are identical, the function of each is defined during installation by setting the DIP switch on the board with the code for the parameter group it will control.
At this point, we wonder how the rest of the disassembly will proceed.

The two fans block access to the effects and, in front of them, there are the control boards. On one side of the head, the PCB is mounted on a hatch, for quick access to the optical system. By removing the two screws that hold it in place, this rotates on hinges and allows wide access for routine maintenance of the zoom, the focus, the two frost filters and the prism.
The same type of solution has been implemented for the fans. They are hinged on an axis and held in by two screws but, in addition, a spring holds them in place when they are in the open position. As they are located on the CMY module, the disassembly is easy. The follow-up is easy. Just simply remove the two bracket screws and disconnect the ribbon cable to extract the module. This requires a little attention, to prevent damage to cable or color flags, but it’s not brain surgery.
The fans can then be folded back to take down this element and work easily on cleaning or repair. The CMY module has four pairs of flags: cyan, magenta, yellow and CTO, manufactured thru a nanosecond laser percussion process, providing a better transition between saturated and pastel hues and increased uniformity, regardless of the zoom setting.
The other module is strip away as easily as the first one. It is made of two plates between which are housed the iris, the two rotating gobo wheels, the color wheel, the effects wheel and the shutter! A small impeller is positioned to cool the elements between the two plates. The disassembly of this module is considered level 2 service, and thus requires a Torx screwdriver. Each plate incorporates three parameters. The glass effect wheel is magnetized, allowing for easy and quick interchangeability.
The gobo wheels are equipped with seven slots to accommodate six glass gobos, with an image diameter of 26 mm. They are mounted on a removable support and, thanks to a “poka-yoke” alignment key, the images will always be positioned with the same orientation in the gobo holder. Thus, the user will always find the same indexing of the gobos without having to reprogram, even after disassembly or after substituting a unit. Obviously enough, it’s not necessary to open the module to change the gobos, or even to disassemble the fixture.
We then can remove the two covers of the yoke. In the horizontal part are the two impressive hybrid, three-phase stepper motors that provide the movement of the head on two axes. In the arms on one side we find the pan control board, as well as the tilt lock.
On the other side is the belt and the gears that drive the head on its axis. On this side, but on the side of the head itself, is the access to the lamp ignitor.
Just in front of the lamp is the mechanical dimmer. The two blades are covered with a frosted glass portion that enables a more discreet insertion of the saw-teeth into the beam. It has a raised cover plate that serves to protect it during the removal of the CMY module but, more importantly, to redirect the stray light from the lamp back into the reflector and, thus, back into the beam. At Claypaky, they won’t let a single photon be wasted!
On the back of the head are the access to the lamp and its adjustments. The lamp housing is completely closed, allowing for better control of the temperature in the head. To see the reflector, we have to remove the cover, but since Rémi has his certification, we can go on without hesitation! The cooling of the compartment uses two tangential fans with a good performance ratio of volume of air against noise.
Now let’s move on to the base. Removing the two covers, we find part of the power supply section. The rest is sealed in metal boxes. Fortunately, the two sides come off easily and the motherboard located behind the display can be accessed. Between the two is the battery that allows the user to change the projector settings without external power. If it starts to lose its charge, one simply has to remove the motherboard from its four spacers to change it. We note that a short rubber strip runs on the sides of the base with catches that hold it, for better resistance to moisture.
The tests
To show the evolution of the products of this Italian manufacturer, we set up this new spot next to an Alpha Profile 1500. We strike the lamps and let them warm up. 3, 2, 1 Go! Rémi opens up both dimmers and the “Wow effect” makes complete sense, the Spot 1500 literally pales in comparison with its young successor and its white seems to go a little green!
The Master of Ceremonies gives me another layer with color mixing.
We review the colors on both fixtures and there is no doubt about it: with this new lamp – of which this example is not even at its best yet, since it reaches a CRI of 95 after a hundred hours of use – the color range is greatly extended and there are colors that we had certainly never seen on fixtures of this brand.
Scenius maintains a wide range of blue, like its older brother, and there are no big changes to magenta and yellow, but when you mix these last two colors, this is where there is a difference like day and night between the two sources. While the Alpha struggles to create a deep amber, Scenius puts out a “real” CMY red. The same goes when mixing blue and yellow, you can obtain a green that “holds up” and is bright.
So we took a little time to test the possibilities of this new color mixing: blends of colors and very fast or very slow transitions. This really is one of the biggest strengths of this new fixture, and new for Claypaky, whose color mixing has lacked red and green until now.
There is now a very wide range of colors with hues ranging from pastels to the brightest saturated colors. On top of that, there is light! This spot also has a progressive CTO filter that doesn’t quite go as low in color temperature as that of the 1500, since the minimum temperature is 3200 K (versus 2800 K on the Alpha Spot). There is of course a color wheel equipped with two reds, one blue, a green, an amber, a UV and a 1/2-minus green filter, which should be very useful for video capture or for the photography of a fashion show, for example.
The new palette uses all the potential of the CRI 95 source:
On the subject of filters, unfortunately Scenius doesn’t have a progressive frost, but has two different frost filters, instead. The lighter of these two softens the edges of the beam, while the second, heavier frost, almost completely flattens it out. Not far away from these, physically, is the fixtures single 4X prism. Continuing our journey in the direction of the lamp, next we find the zoom and the focus. We measured a minimum sharp beam at 9.75° and a maximum sharp beam at 48.55°, which is pretty close to what the Italian manufacturer declares for the full focused zoom range (8° – 50°).
No surprise as far as optics are concerned: Claypaky has mastered this craft, just like the movements of the zoom, which can be as slow and smooth, as they can be very fast. Console operators will be able to have fun programming effects such as rain drops or larger, more dynamic effects, even with a small number of fixtures.Next, we come to the second module, which closest parameter is the iris. Here again, there’s nothing new – when the iris is closed, we recognize the tight spot beams of the Italian brand.
The second half of the DMX range of this parameter is for iris pulsation effects, so you need to be careful when programming the opening and closing of the iris not to exceed the value 127, or 50%. Next come the graphic effects: 2 gobo wheels almost against each other, leaving only enough space between them for the animation wheel. This group of three parameters allows for a multitude of combinations.
The gobos selection
The choice of the 12 gobos seems well thought out indeed. They can be used both for aerial effects or for projection in a mix of classic and original gobo designs. The user will be able to do original things, but without taking too many risks. During these projection tests we do note, though, some more pronounced sharpness defects than with the Alpha series.
The last parameter in the head is the dimmer. It is practically up against the lamp and perfectly positioned to remain as discreet as possible. As you can see in the video, even with a long transition time, there is no jerking and the fade to black is smooth. There are still some details to work out, as the definitive curves are not completed.
Coming to the end of the physical parameters, I ended the test with pan and tilt. The video with the timestamp is really useful, because during testing I had the impression that the movements were rather slow, although 1.2 s to rotate 180° in tilt is very well ranked in its category. In pan, it takes 2.05 s to complete the same 180° range. This performance is not bad, but a slight improvement would be welcome.
For the rest, it does just fine – diagonal movements are smooth and the stops are precise. The reset parameter is divided into four parts: obviously, one with no reset and a second with a complete reset. The remaining two intermediate ranges allow independent recalibration of different parameters: one of pan and tilt, the other of effects.
DMX channel 32, in whatever mode, controls the lamp: turning it off or switching it on at 1200 W or at 1400 W. Finally, I invite you to take a look at the DMX chart regarding the “Function” parameter (DMX channel 30). Manufacturers are providing us with more and more menu options that can be controlled via the console. These are often quite useful when doing programming that requires fine tuning. For example, shifting the pan and tilt speed from fast to slow can help to lengthen transition times without jerky movements, while you can switch back to fast speed for more dynamic effects.
The results
Narrow beam
Now, time for figures and numbers. Of course, we start our first illuminance measurements with the tightest possible in-focus beam.
The illuminance in the center is 66,000 lux. With a beam divergence of 9.75°, the luminous flux in this case reaches 27,000 lumens. The intensity curve is very smooth with a rounded peak. Claypaky favors good light distribution.
20° beam
Next, we take our reference measurement with a 20° zoom setting. Here, the illuminance in the center is 15,870 lx and the luminous flux jumps up to 29,434 lm. The curve is equally regular with very rounded apex.
Wide beam
The largest focused zoom setting, 48.55°, measures 2800 lx at the center, for a luminous flux of 28,252 lm.
The dimmer curve in “Linear” mode shows the profile of a “Square-Law” curve even more. As mentioned earlier in the article, this part of the software was not finalized at the time of this present test.
See below: illuminance values for colors, as a percentage of white.
Conclusion
Claypaky did not make it to the top for no reason and, as always, the Italian brand has launched a well-designed and well-built product. Its light output is beautiful, powerful and uniform. The color palette is complete and it offers a wide range of hues and effects.
This new spot has everything it needs for success and should be appreciated by a large number of lighting designers and directors of photography. As Claypaky takes everyone into consideration, the maintenance aspect has not been forgotten and technicians will definitely appreciate the ease of access to the various elements.
