In fact, if the lights are not too close or the colors are too noisy, there is no need to use the background. As long as there is no light from the camera to cause reflection, the light of the lamp itself will be highlighted.
Jewelry and the like are unnecessary. A lamp that glows itself will reflect light when illuminated by a jewelry lamp, which will affect the image of the lamp itself.
If it is dark around, it has no effect on the photography of the lamp itself. Using M-file instead, using large aperture, tripod and close focus, and properly adjusting exposure time will have good results. If there is a lot of noise, it is because the ISO is too high, so adjust the ISO not to exceed 400.
If there is no camera that can be adjusted freely, it is suggested to change the camera metering mode to spot metering (most cameras have it) and shorten the focal length.
