A continuous light stays on, so you see exactly how the light falls on your subject before you shoot. It suits video, product work and beginners who want to learn lighting visually. Choose based on output, colour quality, adjustability and how you plan to power it.
Why Choose Continuous Over Flash
With flash you judge the result after the shot. With a continuous light, what you see is what you get, which makes it easier to learn how angle and distance change the look. It also works for video, where a flash is no use. The trade-off is that continuous lights are usually weaker than flash, so you may need a higher ISO or a slower shutter speed.
Key Features to Compare
- Output: how much light it gives. Makers describe this in different ways, so check the maker’s guide and compare like with like.
- Colour quality: look for information on how faithfully it renders colour, since poor quality can make skin and products look off.
- Colour temperature: some lights are fixed, while others let you adjust from warm to cool to match the room.
- Dimming: smooth control lets you set the power without moving the light.
- Flicker: some lights can flicker on video at certain settings, so check how the light behaves.
Panel, Tube or Bulb
Each shape has its role, and many people end up owning a mix.
| Type | Best for | Watch for |
|---|---|---|
| Flat panel | Interviews, portraits, desk setups | Harder light unless diffused |
| Tube | Accent and background light | Limited reach |
| Bulb and softbox | Product and still life | Bulk and heat |
Power and Handling
Mains power gives steady output for long sessions, while a battery lets you work on location. Some lights accept both. Lights can get warm in use, so allow ventilation, do not cover them, and follow the maker’s safety instructions. Check that your stand is stable for the weight of the head and any modifier.
Think about modifiers as well. A softbox or diffuser spreads the light and makes it more flattering. Check that the light has a mount that fits the modifiers you want.
Set the light slightly above eye level and angled down for a flattering look, and move it closer for softer, stronger light or further away for a gentler effect. Keep cables tidy and tape them down where people walk. Practise with one light in a quiet room before a real shoot, so the controls feel familiar.
FAQ
Is one light enough?
One light with a diffuser or reflector can produce good portraits. A second light helps with backgrounds or hair, but it is not required when you begin.
Can I use a continuous light outdoors?
You can, though strong sunlight easily overpowers it. It is more useful in shade, at dusk, or indoors.
The Short Version
Choose a dimmable light with adjustable colour temperature and a mount for modifiers. Match its form to your work, and check its power option. Add a diffuser, and you have a flexible tool for stills and video.
