Checkline LS-9-LED Inspection Stroboscope 120 LEDs in 15 x 8 array

Price: $1,995.00 to $2,395.00
120 Hi-powered LEDs produces peak brightness of 7500 Lux

LED Inspection Stroboscope, 9 Inch Width covers web widths up to 16" (400mm) and wider

Flash rates up to 120,000 fpm (2000 Hz) for even the highest speed applications
Adjustable brightness and image sharpness allows optimal setting for each application

The new LS-9-LED is a high-performance stationary LED-stroboscope with powerful light output and uniform light distribution over a large area for use on web-widths up to 500mm (20 inches) and wider.

High light output
Due to the use of 120 of the industry's latest high-performance LEDs, the LS-9-LED offers a powerful light intensity. The large, homogenous illumination surface delivers superb results even at difficult light conditions, making the LS-9-LED suitable for a very wide range of measurement, observation and inspection functions. It is especially suitable for demanding applications, such as those in the printing industry.

Superb image sharpness
With an adjustable flash duration from1-1000 μseconds, you will easily find the best combination between light intensity and sharp images for every application.

Flexible adjustments to all applications
Alternatively, the stroboscope can be controlled directly by the trigger signal of your system without the need for additional control units or by various RT STROBE control devices. When using these trigger options simultaneously, you can easily alternate between the signal inputs by using the switch on the reverse side of the device.

Additional control options

  • LS-5-FCM - a simple and inexpensive unit for controlling flash frequency. You simply insert this small control unit into one of the sockets on the reverse side of the device.
  • LS-5-RCU - for adjusting the flash frequency, phase shift, delay time and trigger divider. This unit is connected to the stroboscope by cable and provides the convenience of remote control even if the stroboscope within your machine is difficult to access.


  • LEDs provide lifetime use and never require replacement
  • Extremely bright and uniform light distribution over an area of 300 x 500mm (12" x 20")
  • Uses 120 of the newest generation LEDs in a 15 x 8 array providing 7500 Lux, peak
  • For web widths > 500 mm (20"), Two (2) or more strobes can be connected in parallel
  • Requires 24V DC Power (Not Included), An optional power adapter is available.
  • Connection include two (2) trigger inputs and 1 trigger output. Power can be connected in either of these 3 locations
  • Adjustable brightness and image sharpness permits operator to optimize strobe for each application.

LS-9-LED-WB - Wide-Body Housing Configuration

We offer a special configuration of the LS-9-LED Linear Stroboscope packaged in 440 mm width housing (17.3 inches) designed to provide a more aesthetically-pleasing solution when the strobe is fixed-mounted on a machine frame that is 18 inches or wider (460 mm+). 

The 120 LEDs are spread in three (3) separate "clusters" each containing 40 LEDs, arranged in a 5x8 array. The position of each "cluster" is optimized to provide the optimal light uniformity over the entire illumination area with the same effective brightness as the standard version of the LS-9-LED (7500 Lux, peak). This model is popular with OEM Machine Manufacturers of Slitter/Rewinders and similar machines used in the label and printing industries
