For most wedding work, a speedlight is the more practical everyday flash because it is small, light and quick to move, while a monolight gives more power and consistent studio-style output for formal portraits. Many wedding photographers use both, choosing by the part of the day.

What Each Light Is For
A speedlight is a compact flash that sits on a camera or on a stand, powered by AA batteries or a small pack. A monolight is a larger flash head with its own power supply, usually mains powered or running on a battery pack, and it often has a modeling lamp and a mount for larger modifiers.
Key Differences
| Trait | Speedlight | Monolight |
|---|---|---|
| Portability | Very high | Moderate to low |
| Power output | Lower | Higher |
| Modifiers | Small, clip-on or umbrella | Large softboxes and reflectors |
| Best moment | Reception, candid, ceremony fill | Formal portraits, group shots, outdoor fill |
When a Speedlight Wins
- Fast-moving receptions where you bounce light off ceilings and walls.
- Venues with limited space, where a large stand is a hindrance.
- Off-camera setups with a wireless trigger and a small softbox.
When a Monolight Wins
- Formal couple and family portraits where you want soft, even, repeatable light.
- Bright outdoor sessions where you need to balance the sun.
- Long sessions where fast recycling and consistent output are important.
A Simple Working Plan
- Use a speedlight on camera, bounced, for dark ceremonies where flash is permitted.
- Switch to an off-camera speedlight with a small softbox for the reception.
- Set up a monolight with a larger modifier for formal portraits if you have room and time.
- Carry spare batteries and a backup light either way.
As general guidance, set the camera to manual exposure around f/2.8 to f/5.6, a shutter speed of roughly 1/125 to 1/200 for flash sync, and adjust flash power until skin tones look natural.
Modifiers shape the result more than the flash head itself. A small softbox or a bounce card can make a speedlight look far softer, and a large umbrella or octabox turns a monolight into a flattering portrait source. Practice at home before the event so you know your power settings, and always agree with the venue and the couple about where flash is allowed. Carry a spare light and extra batteries, because a failure during the ceremony cannot be repeated.
FAQ
Can a speedlight handle a full wedding?
Many photographers do exactly that, using bounce and small modifiers. Power is the main limit outdoors in strong sun.
Is a monolight hard to travel with?
It is bulkier, so plan for a stand, a power source and a bag. Battery-powered models reduce the cord problem.
The Short Version
Choose a speedlight if you want speed and light carry. Add a monolight for formal portraits and outdoor sessions. Confirm brand compatibility for your triggers and camera.
