The Profoto B1 and B10 are both battery-powered, wireless off-camera flashes, but they sit in different size classes. The B1 is the larger, more powerful monolight style unit, while the B10 is a compact, lighter head designed for travel and fast setups. Verify current power figures and kit contents on the maker’s page.
What Each Flash Is For
The B1 is aimed at location work where you need strong output to overpower sunlight or fill large modifiers. It has a full flash head with a built-in modeling light and works with Profoto’s wide range of light shapers.
The B10 is a smaller head that follows the same system but fits into a compact bag. It suits environmental portraits, small events and shooters who want to travel light.
Differences at a Glance

|---|---|---|
| Size and weight | Larger and heavier | Compact and light |
| Power class | Higher output | Lower output |
| Best use | Large modifiers, bright outdoor light | Travel, small modifiers, quick setups |
| Modeling light | Yes | Yes, LED |
| Wireless control | Profoto Air system | Profoto Air system |
How to Decide
- List your usual modifiers. Large softboxes and umbrellas call for more power.
- Think about ambient light. Outdoors at midday needs much more flash power than indoors.
- Consider how far you walk to a location and how much you can carry.
- Check how many flashes per battery charge you need for a full session.
- Look at what you plan to add later, since both work with the same controllers and many shapers.
Location Lighting Tips
- Set your camera to manual so the background exposure stays independent of the flash.
- Lower the ambient exposure first, then add flash on the subject.
- Use a stand with a sandbag outdoors, since modifiers catch the wind.
- Keep the flash closer to the subject for softer, more even light.
- Take a test frame and check the histogram before shooting a full set.
Think about a typical day on location. A portrait session in a park might need only one light and a modest modifier, while a commercial shoot beside a bright window might need much more output and a second head. Plan around your most demanding job, not your easiest one, then check whether the smaller unit still copes with it.
Also consider the rest of the kit. Stands, bags, batteries and light shapers add weight, so the true difference between the two systems shows up when everything is packed together.
FAQ
Can the two be used together?
Yes, because they use the same wireless system. Many photographers use a main light plus a smaller accent light.
Is the smaller one enough for portraits?
For many portrait setups with moderate modifiers, yes. Very large modifiers or bright sun are where extra power helps.
The Short Version
Choose the B1 if you need more output and work with large modifiers in tough light. Choose the B10 if you value a lighter bag, quick setups and travel friendliness. Check current output figures and battery details on the maker’s page.
