Detailed Answer
IP54: dust-protected (partial) + splash-proof; IP65: dust-tight + water-jet protected. Differences: 1. Dust (5≠6 — IP65 is dust-tight); 2. Water (4 = splashing, 5 = jets). For industrial environments, IP65 and above is recommended: no dust can enter and rain jets are tolerated. The entire LIDER LD series is IP67 (above IP65); XINGJIA's entry series is IP65.
| IP54 | Dust-protected + splash-proof |
| IP65 | Dust-tight + water-jet proof |
| Industrial rec | IP65 and up |
Note:For dusty workshops, go straight to IP6X.
