The GlareOne Botis 400 is a 400W battery-powered flash designed for fast-paced location and studio work, with integrated TTL, HSS, and a 30W Bi-Colour LED modelling light. It delivers consistent daylight-balanced output with short recycle times, strong modifier efficiency and enough battery capacity to cover long sessions without stopping to recharge. The compact body and Bowens mount make it easy to integrate into existing lighting setups.

Efficient 400W power

The GlareOne Botis 400 has a maximum output power of 400W, but offers performance that rivals other 500 and 600W lights. The flash tube design and reflector efficiency translate into noticeably strong output, particularly when working with standard reflectors or more focused modifiers. A strong output makes it suitable for overpowering daylight outdoors or for lighting larger studio setups without pushing the unit to its limits. With a range of 0.01-9 seconds, recycling remains quick even at higher power, helping maintain rhythm during portrait or commercial sessions.

Consistent colour and modifier-friendly light

The Botis 400’s protruding open flash tube produces an even, well-distributed beam that fills softboxes, umbrellas and beauty dishes cleanly. Colour temperature remains stable around 5500K, so skin tones and product colours stay predictable across a shoot. A protective glass dome shields the tube without affecting light spread, which is reassuring when packing and unpacking on location.

Freeze mode for motion control

Freeze mode is where the Botis 400 becomes more than a general-purpose flash. With flash durations as short as 1/20,200 s (t0.5), it allows you to stop motion reliably, from splashes and fabric movement to fast human action. The screen displays the actual flash duration at each power setting, making it easier to choose the right balance between output and motion control rather than guessing.

Built for long sessions on battery

The supplied lithium-ion battery delivers up to 500 full-power flashes on a charge, which comfortably covers long location days or busy studio shoots without swapping batteries. Active and passive cooling allow up to 180 consecutive full-power flashes, useful during dynamic shooting where stopping for cooldowns would break the flow. Charging is straightforward, and the battery system is compatible with the Botis 600 for shared power management.

Integrated wireless control

The built-in 2.4 GHz receiver slots straight into the GlareOne system, working with compatible triggers and master flashes. With 16 groups and 32 channels available, multi-light setups remain organised even in complex environments. Visual group indicators on the housing make it easy to confirm settings at a glance when lights are placed high or tucked behind modifiers.

FAQs:

Does the GlareOne Botis 400 support TTL and High-Speed Sync?

Yes. The Botis 400 supports both TTL metering and High-Speed Sync up to 1/8000s. This allows you to work quickly in changing light or balance flash with bright ambient conditions outdoors. TTL can be overridden manually when more control is needed.

How effective is the Freeze mode in real use?

Freeze mode provides flash durations from 1/530s down to 1/20,200s (t0.5), which is short enough to stop most fast motion. It is beneficial for action, dance or creative splash photography. The ability to see flash duration on the display helps you choose the correct power level for sharp results.

Can the Botis 400 be used with third-party modifiers?

Yes. The GlareOne Botis 400’s Bowens mount supports a wide range of modifiers from GlareOne and other manufacturers. Softboxes, reflectors, beauty dishes and snoots fit without adapters, making it easy to use existing light-shaping gear.

Is the LED modelling light suitable for video?

The built-in 30W Bi-Colour LED modelling lamp is useful for previewing light placement and for simple hybrid photo and video work. It offers a 2700K to 6500K range, making it flexible for mixed lighting conditions. While not a replacement for dedicated video lights, it works well for close-range or accent use.

How portable is the Botis 400 for location work?

With a compact body and battery, the Botis 400 travels well for location shoots. The light alone weighs 1995g, and with the battery attached, it weighs 2480g. The included carrying case protects the head and accessories, and the weight remains manageable even when paired with larger modifiers. This makes it practical for photographers who move frequently between setups during a shoot.

What accessories come with the GlareOne Botis 400?

The Botis 400 is supplied with a reflector, a set of colour filters, and a grid, giving you immediate control over beam spread and colour. The reflector provides a punchy, efficient light for general use, while the grid helps narrow the beam for more controlled or dramatic lighting. A dedicated carrying case is included, making it easier to transport and protect the light and accessories.
