  • LED Light Source

    niji - Bluebox Optics

    Go mercury-free. niji, the new state-of-the-art LED light source helps to eliminate mercury from microscopy.

  • LED Light Meter

    Extech LT40 - Extech Instruments Corporation

    The LT40 LED light meter is useful for measuring and optimizing environmental light levels in a wide range of environments, including office buildings, manufacturing plants and warehouses, university campuses, schools, hospitals, and many other locations. OSHA regulates workplace lighting because illumination must be adequate for assigned tasks, and light meters are used to verify regulatory compliance, as well as state and local public safety codes and ordinances. Use of LED lighting is on the rise because it is more efficient to operate, it emits stable, high quality illumination, and the technology is dropping in price. Besides LED lighting, the LT40 can measure standard light sources fluorescent, metal halide, high pressure sodium and incandescent up to 400,000 lux (40,000 Fc). The LT40 comes with a built-in sensor with protective cover, 2 AAA batteries, storage pouch, and user manual.

  • Light Flicker Meter

    LiFli - Fauser Elektrotechnik

    The LiFli light flicker meter enables fast evaluation of light sources on the flickering part (flicker / flicker). Especially in the case of LED lamps, the flicker portion can be determined only by one measurement, since it is in the range of 0% to 100% for these luminous means.Audio features enable the flicker to be reproduced acoustically. A voltage output for further analysis by means of oscilloscope or voltage analyzer is available.

  • Light Level Meters

    General Tools & Instruments

    Our light level meters have the measurement range needed to support commercial and industrial tasks such as photography, UV curing and sterilization, semiconductor fabrication and checking thermal window efficiency. We offer one- and two-piece models and data logging models with thermocouple ports that are designed to measure the intensity of full-spectrum light or two specific wavelength ranges: UVA and UVC.

  • Trailer Light Testers

    Pro-Check 725 - LITE-CHECK LLC.

    Pro-Check trailer light testers with advanced electrical diagnostics are rugged, lightweight, and economical. They independently test each electrical circuit on a trailer to ensure proper connectivity. The Pro-Check identifies each specific type of electrical wiring fault. Lite-Check’s patented active diagnostic system takes the guesswork out of identifying trailer light and electrical problems. The Pro-Check commercial trailer light tester with electrical circuit diagnostics, not only identifies faults, but the specific circuit the fault is on. Faults are identified as “Open Circuit”, “Open Ground”, “Short” (w/all circuits identified), or “Chassis Ground”. Audible alarms alert technicians to found electrical faults.
