[c300d-II]

Powered by user feedback, the new and improved 300d Mark II is 20% brighter, more durable, more portable, and more intelligent than the original 300d LED. Change the way you light using the Sidius Link Bluetooth and Wifi app gives you more control and the built-in FX features are hopefully more useful then just a gimmick. When combined with the Fresnel 2X, the 300d Mark II can produce up to 80,000 lux. And as always, the 5500K‐balanced 300d Mark II maintains impeccable color fidelity with CRI and TLCI ratings of 96+ and 97+ respectively.

The improvements include a single ballast which will allow the light to go to 50% with just one Vlock battery being used - there are still 2 x Vlock ports on the ballast - one is marked in red and can be used on its own if needed. We have tested this with our 150w Vlock batteries and all seems good but Aputure still say you need 340-350W (15A) available for this solution. You also get a better way of attaching the ballast to your light stand with a heavy-duty cord hanger as well as a c-stand clamp and lock system that works very well. There is no fan in the ballast either so no extra noise. They have changed the cabling to locking power cables too which take a few mins to get your head around how they work, but all feel very nice.

The C300D II vs the C300x

We ahve been asked by a few customers what is the difference in light output between the C300d II and the newer C300x.
The new C300x does have adjustable colour temperature which does amke it look more attractive at a glance vs the C300d which has a fixed daylight temperature.
However the colour temperature settings come at a cost. It comes down to how much light the lamp emits. This is measurted in either lumens or footcandles.
With the reflector dish, the C300d II emits 3500 lux or 325 footcandles measured at 3m. However the C300x emits 1300 lux (121 footcandles) at 3200k and 1700 lux (158 footcandles) at 5500k - the same temperature as the C300d II.
So overall you get less than half the ligth output. This is due to the way the light is contructed. In the 'd' model, every LED chip is emitting one colour temperature. But the 'X' model had 50% set to 3200k and 50% set to 5500k. So at either end of the spectrtum only half the LED's are working thus halfing the output. We found this to be true also of our older Aputure light panels which had adjusable colour temperature. the highest output is at 4300k when both sets of  leds are being used. But even then it maxes out at 2100lux (195 footcandles). Only about 2/3 of the output of the other model.

So that's the big difference. Convenience vs light output. Of course you can always use gels...

Stepless dimming to zero:

Brightness now goes down to zero - yes 0% so this light can be your brightest and your lowest. This is also step less dimming control from the unit or from the remote / app and can you utilize any of 4 different dimming curves: Linear, Logarithmic, Exponential, and S‐Curve.

Wireless control is now via Wifi and /or Bluetooth - you can turn these on/off on the switches - use the Sidus Link utility app for controlling the light remotely. The light also has DMX control with DMX pass through and a 'Studio Mode' that lets the lights come on instantly for DMX control.

Cool Lighting Effects built-in:

The control box of the 300d Mark II features 8 built‐in lighting FX: “Paparazzi”, “Fireworks”, “Lightning”, “Fault Bulb”, “TV”, “Pulsing”, “Strobe”, and “Explosion”, with more coming in future firmware updates via the control boxes USB interface. The control box also features a new “trigger” button to activate lighting FX instantly. There was talk of Candlelight and new ones coming in the future through firmware so we will update if/when available.

55 degree Hyper reflector:

The 300d Mark II features the all-new, hyper efficient 55° reflector. By slightly narrowing the beam from 60° to 55° and redesigning the inner shape and coating of the reflector, they have increase the output of the 300d II by more than 3 times, when compared to the original design.
