Is it better to shoot the portrait of Jinbei sun 150w or the portrait of Jinbei sun400 quadruple lamp (with 4 bulbs)?

Generally speaking, 4 lamps are better than 1 lamp, and the brightness of 1 lamp is usually hot, and the light of special bulb is always 4 lamps.

The difference between a flash and a normally lit lamp: the flash flashes instantly to achieve brightness.

The advantage is that the flash won't be on all the time, and it has high durability (my friend used it for five or six years and it broke down several times)

The disadvantage is that sometimes the huge light is too dim to be a little dizzy.

(So there are also photo studios that use flash lights to light the reflector, depending on the photographer's purpose. )

Always turn on the light, the electricity bill should also be taken into account, the temperature generated by the light will sting your eyes if it is too bright, and there is also the cost of changing the light bulb.

Mix and match is a test of your light level (it takes a long time to debug the light). It is recommended to mix and match less.
