Photographic lamp 2700k (105w) is brighter or brighter than (household light bulb 200W).

If you're asking about brightness, it's only related to the wattage of the lamp.

But it depends on what kind of light bulb you use.

If they all have filaments (tungsten lamps), the ones that emit light must have a large wattage.

If you compare the energy-saving lamps with those in tungsten lamp, there is a conversion.

Because of the different luminous efficiency, energy-saving lamps are about 3~5 times brighter than ordinary tungsten lamp.

If so, your 105W photographic lamp (energy-saving lamp) can reach the brightness equivalent to 300 ~ 500W of ordinary household light bulbs (poor brand quality).

"Which is brighter and which is brighter" is a question, right?

Another problem is the color temperature.

The concept of color temperature can be found online, so I won't say much.

The color temperature k value is low and the color is warmer; The color temperature k is high and the color is cold.

Energy-saving lamps are generally divided into warm light of about 2700K and cold light of about 6500K K.

Choose the right color temperature lamp according to your needs.

In the actual shooting process, you can also fine-tune the digital camera through the manual white balance function to achieve your goal.

If it is film shooting, it can also be adjusted by choosing different kinds of film, Leiden filter and CC filter.
