If the power is the same, the brightness of the LED light tube and the brightness of the LED bulb are the same.
You feel different because the light source of the bulb is more concentrated is a point light source, and the lamp beads in the light tube are arranged separately, so the light is also scattered to give people the feeling that the bulb is not bright, which is an illusion. The brightness of the lamp is actually the ability to convert electricity into light per unit time, only related to power.
If the power of the same lamp bead color temperature should be the light bulb to feel brighter, this is because the lamp bead is more concentrated and the lamp bead is dispersed, the luminous area is relatively large, so it looks like the led lamp is not as bright as the lamp, in fact, it is a feeling of the human eye, in fact, as long as the lamp bead is the same power, no matter what kind of lamp is similar.
