Which is better, a raw meat lamp, a light bulb or a lens?

Lens lamp beads have better light gathering effect and light propagation efficiency. Lens-type lamp beads adopt lens design, which can concentrate and focus light more, provide longer irradiation distance and stronger brightness. Lens-shaped lamp beads can also effectively reduce light scattering and waste, making the lighting effect brighter and more uniform. In contrast, although the price of raw meat lamp beads is low, because there is no lens design, the focusing effect and propagation efficiency of light are poor, and the illumination distance and brightness are not as good as those of lens lamp beads. Generally speaking, lens lamp beads are better in lighting effect and experience, so lens lamp beads are good.
