1. Convenience
Different lamps are installed in different ways, and the process of disassembly is different. How easy is it to set up and remove the lights? Does it use 5-pin DMX or 3-pin, and how does it compare to other lights? How heavy is this light, suitable for one person to install, or need an assistant.
2. Durability
How long will your gear last? Find an interesting phenomenon, whether it is concert stage lighting fixtures or theater lighting fixtures, the lighting engineers who use them will always take gentle care of them. Or will your lights be fixed and only move once a year, or even less? Does it matter if there is only a cheap price? While considering durability, you also want to see the service life of this lamp. I really want to see if the manufacturer really believes that the luminaire is enough to guarantee that it won't have a serious light decay in one or two hundred days!
