The Top Monolights with Built-in Batteries

June 1, 2016

By Greg Scoblete

The battery-powered strobe is something of mash-up: part speedlite, part studio strobe. These lights are a great option for working on location where outlets are scare to nonexistent and lugging power packs isn’t attractive.

Pioneered by Profoto’s B1, the category has steadily grown to include a variety of manufacturers, price points and capabilities.


Broncolor Siros L

The newest of the crop, the Siros L is based off the original Siros and offers Wi-Fi for remote control via an Android or iOS device. You can also trigger the flash using the RFS 2.1 transmitter, sync port and optical slave. Each flash has a 9-stop power range with 1/10-stop adjustments. Additional features include a USB port for firmware updates, 25-watt LED modeling lamp (3200K), an external flash tube and compatibility with Broncolor light modifiers.

Profoto B1

We have the B1 to thank for the birth of this flash category. Introduced in 2013, the original blending of speedlite and studio strobe ushered in even greater mobility for high-powered flash photography. In the fall of last year, the light received new firmware that delivered faster shooting in manual mode for Canon cameras. According to Profoto, the quicker pace will be most noticeable for those shooting with the 1D-X. Thanks to better integration with Canon models, it will also be possible to select TTL or manual mode in the camera menu instead of only on the Air Remote itself. You’ll also now have the option to deactivate auto power-off, which before turned off both flashes after 60 minutes of inactivity. The Air Remote display will no longer turn black after 30 seconds of inactivity but will instead dim partially after 20 seconds but stay readable for up to 100 seconds before going dark.

Output: 500 w/s

Flash Duration at Full Power (t.05): 1/1,000

Recycle Times: 0.1-1.9 seconds

Full Power Flashes Per Charge: 220
