The Basler Standard Light Bar-45x300-x is a wide bar light with a 45 x 300 mm luminous area and a recommended working distance of 10–500 mm, offered in four LED variants (White 5000 K, Red 625 nm, Blue 465 nm, IR 850 nm). It runs on 24 VDC (+/-5%) with about 24 W power consumption via an M8 4-pin connector, and integrates an internal LED controller supporting continuous and strobe operation, with optional compatibility with the Basler SLP Strobe Controller. The black anodized aluminum housing with PMMA light cover is rated IP54 (IP67 available as separate order numbers), weighs 560 g and measures 54 x 310 x 23 mm. Continuous operating current is 1350 mA for White/Red/Blue and 1800 mA for IR, with a minimum flash time of 100 us and operation specified for 10–30 °C and 30–70% humidity.

The Basler Standard Light Bar-45x300-x is a wide bar light built around a 45 x 300 mm illuminated area, which is the defining geometry here: a long, narrow strip of LEDs rather than a ring or dome. That elongated emission footprint is what makes it useful for grazing or low-angle illumination across larger objects, and for laying down even brightness along a line of travel on a conveyor. Because it is a directional bar rather than a diffuse dome, the angle at which you mount it relative to the part determines what it reveals: positioned at a shallow angle it casts long shadows that exaggerate surface texture, scratches, embossing and edges, while pointed more directly it provides general field brightness for area-scan capture. The recommended working distance spans a wide 10-500 mm, so the same fixture can be used hugging the part for high-contrast raking light or pulled well back to cover a broader scene.
The light is offered in four LED variants that change what contrast you get from the same housing: White at 5000 K for broadband, color-faithful imaging; Red at 625 nm; Blue at 465 nm; and Infrared at 850 nm. Wavelength choice is a contrast tool rather than a cosmetic one. Monochromatic Red or Blue narrows the spectrum so monochrome sensors see sharper, less chromatically blurred edges and can be paired with matching bandpass filters to suppress ambient light, while the shorter-wavelength Blue tends to sharpen fine surface detail and the IR 850 nm variant penetrates certain materials and ignores printed color, which is helpful when you want to read past surface graphics. The White 5000 K option is the one to pick when downstream processing needs true color or when the inspection itself depends on color cues. Note the current draw differs by variant: 1350 mA continuous for White/Red/Blue and 1800 mA for IR, which matters when you size the supply and budget thermal load.
Electrically and mechanically the fixture is designed to drop into a standard 24 VDC machine-vision cell. It runs on 24 VDC +/-5% at roughly 24 W via an M8 4-pin male connector, and it carries an internal LED controller that supports both continuous and strobe operation, so basic on/off and overdriven flash control are available without an external box. For tighter synchronization and overdrive you can pair it with the optional Basler SLP Strobe Controller; the strobe path supports a minimum flash time of 100 us, which lets you freeze motion when the bar is gated to the camera trigger. The black anodized aluminum housing with a PMMA light cover handles heat and protects the optics, the unit is rated IP54 with an IP67 version available under separate order numbers, it weighs 560 g and measures 54 x 310 x 23 mm. Operating temperature is specified for 10-30 C (up to 45 C with heat dissipation) and 30-70% humidity, so in warm or enclosed enclosures you should plan for airflow or a heat path to stay inside spec.
Best for
Low-angle grazing illumination of larger objects to bring out surface defects, scratches, embossing and texture across the long 300 mm emission strip
Conveyor and line-of-travel inspection where an elongated bar lays down even brightness along the direction of part flow, gated in strobe mode to the camera trigger
Surface and packaging inspection where the monochromatic Red 625 nm or Blue 465 nm variant plus a matching bandpass filter raises contrast and rejects ambient light
OCR/OCV and reading past printed graphics using the IR 850 nm variant, which ignores surface color to expose underlying marks
True-color or color-dependent inspection using the White 5000 K variant where faithful broadband illumination is required
Selection notes
Pick the wavelength deliberately: White 5000 K for color-faithful work, Red 625 nm or Blue 465 nm for monochrome contrast and filter pairing, IR 850 nm to read past color, and remember the IR variant draws 1800 mA versus 1350 mA for the others, which changes supply sizing and thermal budget
This is a directional bar, not a diffuse dome, so plan the mounting angle: shallow grazing angles maximize defect and texture contrast while steeper angles give general field brightness; the wide 10-500 mm working-distance window gives room to tune coverage
The internal LED controller covers continuous and strobe operation on its own, but for synchronized overdrive and the 100 us minimum flash time add the optional Basler SLP Strobe Controller and gate it to the camera trigger
Confirm the environment matches the IP rating: standard units are IP54, and if washdown or dust ingress is a concern you must order the IP67 version under its separate order number rather than upgrading in the field
Budget for thermal and electrical fit: 24 VDC +/-5% at about 24 W over an M8 4-pin connector, an operating range of 10-30 C (up to 45 C only with added heat dissipation) and 30-70% humidity, plus 560 g and a 54 x 310 x 23 mm envelope that needs a rigid mount at the long 300 mm span

Applications this camera is commonly selected for. Open one to see the full recommended hardware and approach.
Get a first image quickly with the pylon Viewer, then move into the pylon SDK for your application. These cameras are GenICam/GenTL-compliant, so any compliant vision software can drive them as well.
Download and install the pylon Camera Software Suite for your OS from Basler. This provides the pylon Viewer, the GenTL transport-layer producers and the pylon SDK (C/C++/.NET/Python). On Windows the installer adds the needed drivers; on Linux follow the included setup notes for USB and network permissions.
2. Connect the camera and check the link
Cable the camera to its matching interface: GigE Vision to a GigE port (use a quality cable and, ideally, a dedicated NIC with jumbo frames enabled), USB3 Vision to a USB 3.x port with the supplied cable, or CoaXPress to the frame grabber. Provide power where required (PoE, USB bus power, or PoCXP). Open the pylon Viewer and confirm the camera appears in the device list; for GigE, make sure the camera and NIC are on the same subnet.
3. Grab a first image and set exposure, gain and pixel format
Select the camera in the pylon Viewer and start a continuous grab. Adjust exposure time and gain until the image is well exposed (avoid clipped highlights), set the pixel format (e.g. Mono8 or a Bayer/RGB format), and focus the lens. Use a test pattern if the lens or scene is not ready yet.
4. Configure triggering and acquisition
Decide between free-run and triggered acquisition. For synchronized capture, set the trigger source (software or a hardware line on the I/O connector), trigger mode and any debounce or exposure mode, then verify timing. Note the parameter names you change in the Viewer feature tree, as you will reuse them in code.
5. Move to the SDK or a GenICam-compliant library
Recreate your settings in code with the pylon SDK (C, C++, .NET or Python) to open the device, apply the same features and pull frames into your pipeline; pylon vTools and pylon AI can add processing blocks. Because the cameras are GenICam/GenTL standard, third-party vision libraries work too. Once the image stream is stable, you can route frames to a deep-learning inspection such as Rosepetal for automated defect detection.
