Size & weight
The Godox Knowled M600Bi Bi-Color LED Monolight weighs 10.93 lbs / 4.96kg and the separate power supply/controller weighs 8.24 lbs / 3.74kg.
How does this weight compare to the Nanlite Forza 720B and the Aputure LS 600x Pro? Below you can see.
|Godox Knowled M600Bi||19.17 lbs / 8.7 kg|
|Nanlite Forza 720B||21 lbs / 9.5 kg|
|Aputure LS 600x Pro||22.15 lbs / 10.05 kg|
The Knowled M600Bi Bi-Color LED Monolight from Godox has an adjustable color temperature range from 2800K to 6500K, and claimed CRI/TLCI ratings of 96/97.
The light has four dimming curves and Godox claims that the color temperature remains constant regardless of the intensity level. As well as being able to adjust the intensity and CCT on the fixture, you can also make changes wirelessly with 2.4 GHz bandwidth, DMX, or Bluetooth.
There are 7 lighting effects: flash, lightning, TV, broken bulb, candle, fire, and fireworks.
The M600Bi can be adjusted in 0.1% increments or quickly in 10% increments.
The M600Bi can also be remotely operated via the Godox Light App, RC-R9 remote, or DMX controller.
Bowens S mount
Just like most LED spotlights of this size, the light features a Bowens S mount so you can attach and use a wide array of lighting modifiers.
The light runs can be run via 100 to 220 VAC current using the included controller, or you can use an optional V-mount battery to power the light remotely. The light draws 730W. As a comparison, the Nanlite Forza 720B draws 800W, and the Aputure LS 600x Pro draws 720W.
According to Godox, the light can be powered remotely using either 14.8V or 26V batteries. Above you can see what output levels the light will work when using batteries. These figures are based on a 160Wh V-mount battery or a 26V 260Wh battery.
Just like other high output, high power draw COB LED lights, the Godox features an in-built fan and a rapid heat dissipation system that they claim has extremely low noise even at full power. The fan can be placed in the following modes:
Above you can see what output levels can be used in the various fan modes when using AC power or batteries.
You can pair the M600Bi with the 10″ FLS10 Bowens Mount Fresnel to deliver an even brighter and more concentrated beam. The LB-02 barndoors can also be used to precisely cut and shape the light.
The Fresnel is adjustable from 10° spot and 35° flood.
Godox claims that the M600Bi can output 198,000 lx using the included reflector at a distance of 1m, however, if you look at their published photmetric data that figure is 186,000 lx at 4300K. With the optional FLS10 Fresnel they claim a figure of 40,100lx at a distance of 3m when used at 5600K. The reading of 198,000 lx does not seem plausible for a light that draws 730W.
Above you can see the full claimed output figures for the light at various CCT settings and when used with the optional Fresnel.
So how does this compare to the Aputure LS 600x Pro? Well, below you can see:
|Nanlite Forza 720B||73,000 lx||5397K|
|Aputure LS 600x Pro||68,400 lx||5397K|
As a comparison, above you can see what the Nanlite Forza 720B and Aputure LS 600x Pro output when set at 5600K at a distance of 1m when used with their 55° reflectors. These figures are from my own independent testing.
