LT7 Series Light Towers
Easily build or modify the combination that works for you!
The LT7 light tower combines innovative LED technology with modular style
assembly. This enables the towers to meet the extensive requirements seen in
most status indicating applications. The simple design uses only 9 modular com-
ponents to make a five color tower complete with alarm and flashing functions.
Using the latest and brightest LEDs, the LT7 product range provides brilliant
illumination for all the lens colors. The unique prism cut design enhances the
brightness and ensures outstanding levels of visibility from any direction and
distance.
Key features of the LT7 series light towers include:
• 70mm diameter
• Ultra bright LEDs
• LED strobe modules
• Unique interlocking construction
• Fast and easy assembly
• Optional adjustable alarm
• Lead-free design, RoHS compliant
• IP65 environment protection, NEMA 4, 4X, 13
• Color-coded wiring terminals
• Only nine modular components with 5 lens colors & 4 base units
• UL/c-UL Listed, CE marked File #E245027
