When purchasing laser lights, you need to combine the use scenario, needs and budget, avoid misunderstandings, and then you can choose the right equipment. First, clarify the use scenario. For small indoor scenarios (such as home use, small gatherings), choose semiconductor laser lights with power of 500mW-1W, small size and convenient operation, and prefer RGB full-color models to meet the needs of atmosphere creation; for large outdoor scenarios (such as electronic music festivals, outdoor lighting), choose solid-state laser lights with power of more than 1W, IP65 and above protection level, and support DMX512 control to ensure brightness and stability. Second, pay attention to core parameters. Prioritize products with standard power, small beam divergence angle and long service life, and avoid buying products with false power labeling and poor quality. Third, consider the budget. The price of home models is mostly a few hundred yuan, and the price of professional outdoor models is several thousand yuan or even tens of thousands of yuan. Choose the appropriate grade according to the budget, and there is no need to blindly pursue high power. Finally, choose regular brands. Products of regular brands have guaranteed quality and perfect after-sales service, which can avoid the problem that faults cannot be repaired during use.
