Home / LED Digital Clocks
LED digital clocks
Large-format LED clocks, synced to the second, every second.
Bright, reliable digital clocks for offices, factories, schools and transport hubs, with optional GPS, NTP or Ethernet time synchronization — so every clock on your site always shows the same, correct time, automatically.
Time synchronization
Three ways to keep every clock exactly in sync.
GPS Sync
A cost-effective way to synchronize clock time against universal time coordinates using a GPS receiver — ideal for standalone sites with no network infrastructure.
NTP Sync
Network Time Protocol synchronizes clocks against a computer network time source — the standard choice for offices and campuses already on a LAN.
Ethernet / Wi-Fi
Ethernet-enabled and Wi-Fi clocks connect directly to your network, keeping multiple displays across a building or campus perfectly aligned.
The range
4 and 6-digit clocks, 0.5" to 10" digits.
Choose your digit size by viewing distance — larger digits for factory floors and transport hubs, compact digits for reception desks and offices.
