Product and component testing services is the evaluation of a finished product or component through performance in electrical, life, environmental exposure, dynamic, ergonomic or other specialized tests.  Also testing to standards such as UL 489, CE or MIL-STD 810.

Optical spectrum analyzers (OSA) can divide a lightwave signal into its constituent wavelengths. This means that it is possible to see the spectral profile of the signal over a certain wavelength range

High intensity discharge lamps (HID) contain compact arc tubes, which enclose various gases and metal salts, operating at relatively high pressures and temperatures. HID lamps are often used as UV light sources.

Lighting fixtures and lamp sockets produce artificial light in industrial areas or workspaces, and mechanically hold and electrically connect lamp bulbs to wiring.

Power distribution units (PDUs) have an electrical input and several outputs, often as electrical outlets, for powering multiple devices. 

DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies

Power supplies are devices that produce AC or DC power.  This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters

Power transformers convert power-level voltages from one level or phase configuration to another.  They can include features for electrical isolation, power distribution, and control and instrumentation applications

High voltage power supplies use linear technology to provide one or more DC outputs at voltage levels of hundreds or thousands of volts

Specialty electrical distribution and protection products are specialty or proprietary products related to electrical distribution and circuit protection

Spectral lamps radiate line spectra of various gases and metal vapors with high brightness and spectral purity

Spectral filters are used to selectively transmit light according to its wavelength. They are not to be mistaken with color filters, which can be differentiated by an associated schott glass number

Panelboards and switchgear are electrical distribution devices that convert incoming electrical power into several smaller circuits and provide overload protection in the form of fuses or circuit breakers

Distribution transformers are pole-type transformers that supply relatively small amounts of power to residences. They are used at the end of an electrical utility’s delivery system

Lamps are light sources that emit incoherent light for illumination. There are many different types of products. Examples include fluorescent lamps, halogen lamps, heat lamps, incandescent lamps, LED lamps, projection lamps, spectral lamps, and stage lamps. Specialized and proprietary lamps are also available
