Godox ML40Bi and ML40R: palm-sized LED lights with magnetic mount

Godox has launched two compact LED lights, the ML40Bi and ML40R, that share the same pocket-sized body but differ in color range, FX modes, and output.

Godox continues its impressive release cadence of low-cost portable LED lights with a new pair of palm-sized LED. The ML40Bi and ML40R are built around the same compact form factor, small enough to palm or pocket, and share a magnetic snap-on mount for quick placement on metal surfaces.

43-minute runtime

Both lights run from a built-in 4800 mAh lithium battery, rated for around 43 minutes of runtime at full output, and support charge-while-shooting via USB-C at up to 60 W. The ML40Bi covers a 2800K–6500K CCT range; the RGB-capable ML40R extends that to 1800K–10000K. CRI and TLCI ratings are approximately 97 for the Bi and 95 for the R version.

FX mode count differs slightly across the two lights as well: 11 on the Bi, 14 on the R. Both support control via the Godox Light App, NFC pairing, or on-fixture controls, with Bluetooth range up to 30 m.

Reflective boost

Both lights can benefit from a wide range of accessories from the Godox Mount accessory system

The optional ML-L10 Lens Reflector is purpose-built for both models. Godox claims it boosts output by up to 24× on the ML40Bi and 16× on the ML40R compared to bare output. At 1 m and 5600K, the ML40Bi measures 1060 lux bare and 26,400 lux with the ML-L10 fitted, a multiplier of over 24×. The ML40R comes in lower at 781 lux bare and 12,300 lux with the reflector. The reflector is available separately at $11.90.

The lights are compatible with the Godox Mount accessory system. Both units measure 97 × 46 × 91 mm (3.82 × 1.81 × 3.58 in) and weigh approximately 422 g (0.93 lb) without the reflector. A BG02 battery grip provides extended runtime.

Stuck on you. The built-in magnetic mount on the ML40R allows quick attachment to metal surfaces without additional hardware
