BHK

What BHK does

BHK Incorporated is a privately held specialty light source design and manufacturing company founded in 1975 and headquartered at 760 E. Sunkist Street, Ontario, California. The company designs, manufactures, and sells ultra-violet and infra-red lamps, matched power supplies, and integrated OEM lighting systems, with a portfolio centered on low-pressure mercury analytical lamps (AnaLamp Mercury Lamps), zinc and cadmium lamps (including a 10,000-hour-warranty 10-K Zinc variant), UV grid lamps in standard and high-output configurations, Hot Spot Lamps for fiber-bundle and light-pipe delivery, the modular Lamp Manager system with 0.1% output stability, and a matched line of AC and DC power supplies. Underlying technology emphasizes double-bore fused silica tubing, vacuum-jacket construction for temperature stability, serpentine grid geometries, and proprietary processing techniques that BHK states are not available from competitors.

BHK operates on a quote-based, direct-and-channel hardware sales model, complemented by custom application engineering. Go-to-market is executed through a direct sales team at headquarters plus a global network of regional sales representatives covering Asia, Europe, and North America. Revenue streams consist of lamp and light source sales, power supply sales, and professional services for custom OEM system design, with no public pricing disclosed. Customers are primarily OEMs and integrators in analytical and scientific instrumentation (spectroscopy, fluorometry, wavelength calibration, HPLC), with secondary applications in environmental monitoring (air pollution and SO2 detection) and industrial manufacturing (UV curing, sterilization, wafer cleaning, LCD backlighting, EPROM erasing). BHK reports ISO 9001:2015 SGS certification, a documented 99.8% on-dock quality acceptance rate, and a headcount band of 11-50 employees.

Direct peers

• Excelitas Technologies: Global photonics component manufacturer offering specialty UV, IR, and pulsed light sources for analytical, medical, and industrial applications. Directly comparable to BHK's lamp and lamp-based subsystem business across spectroscopy, sterilization, and curing end-markets.
• Newport Corporation (MKS Instruments): Supplies specialty light sources (deuterium, tungsten-halogen, xenon arc, plasma) and full optical subsystems for photonics, spectroscopy, and life-science research. Overlaps with BHK's Lamp Manager-style integrated UV source systems sold to research and OEM customers.
• Hamamatsu Photonics: Manufacturer of specialty light sources including deuterium lamps, xenon lamps, and LED modules for spectroscopy, analytical instruments, and life sciences. Highly comparable to BHK in selling precision UV-VIS sources into OEM scientific instruments globally.
• Heraeus Noblelight: Specialty UV and IR light source manufacturer producing arc, flash, and deuterium lamps for analytical instrumentation, water treatment, and industrial curing. Competes with BHK in scientific-grade UV sources and shares the same OEM-driven go-to-market model.
• Dr. Hönle UV Technology: German manufacturer of UV lamps, UV-LED systems, and curing equipment for industrial applications. Directly comparable to BHK's UV grid lamp and curing-focused product lines, particularly in European OEM accounts.
• Spectral Products (Optometrics): Specialty light source and monochromator manufacturer for spectroscopy, fluorometry, and wavelength calibration — directly aligned with BHK's analytical instrumentation customer base and mercury/zinc lamp product positioning.

Broad incumbents

• Signify (Philips Lighting): Global lighting incumbent with growing UV-C, UV-LED, and specialty lamp product lines for sterilization, curing, and horticultural applications. Represents the large-scale competitive alternative BHK faces as specialty UV lighting becomes more attractive to mainstream lighting players.
• Ushio America: Manufacturer of specialty and industrial UV lamps, including mercury, xenon, and excimer sources used in semiconductor, analytical, and curing applications. A larger specialty lighting competitor with overlapping OEM customers in spectroscopy and UV curing.
• Horiba Scientific: Major scientific instrumentation group whose spectroscopy division specifies and consumes specialty UV/IR light sources in its own products. A buyer/customer in some cases and a competing supplier in others, making it a strategically relevant comparable to BHK's analytical instrument supply chain position.

Emerging players

• Ocean Insight (formerly Ocean Optics): Supplies modular spectroscopy components including UV-VIS light sources to OEM instrument builders. Competes with BHK where spectroscopy light sources are bundled into miniaturized spectrometer modules, though Ocean Insight is more downstream/integrator than lamp specialist.
