The Sekonic C-7000 handheld spectrometer measures light spectrum, illuminance, colour temperature and colour rendering for professional lighting evaluation. Compare LED and other light sources using one portable instrument.
Choose lighting with measured evidence. The Sekonic C-7000, also known as the SPECTROMASTER C-7000, is a handheld spectrometer for evaluating LED, HMI, fluorescent, tungsten, daylight and electronic flash sources.
For lighting procurement, product comparison or installation checks, start by defining the result you need to verify: illumination at a work surface, consistency between fittings, colour rendering or the spectral characteristics of a light source.
| Parameter | Specification |
|---|---|
| Spectral range | 380 to 780 nm |
| Ambient illuminance | 1 to 200,000 lx |
| Ambient colour temperature | 1,563 to 100,000 K |
| Colour rendering | CRI Ra and R1–R15; TM-30-18, SSI and TLCI/TLMF with supported firmware |
| Additional measurements | Chromaticity, peak wavelength, dominant wavelength and PPFD |
| Memory | Up to 999 measurements |
| Display | 4.3-inch colour touchscreen |
| Spectral CSV output | 1 nm or 5 nm increments through C-7000 Utility |
Functions depend on firmware. Confirm the required measurement modes before ordering.
A useful comparison needs a consistent test setup. Record the measurement position, distance, lamp settings and surrounding light conditions so differences can be interpreted properly.
| Buying or testing question | What to review |
|---|---|
| Does the installation provide the required light level? | Compare illuminance readings at defined measurement locations against the project specification. |
| Do replacement lamps match the existing lighting? | Review colour temperature and chromaticity under the same measurement conditions. |
| How should competing LED products be compared? | Define acceptance criteria for colour rendering and spectral characteristics before testing samples. |
| What information is needed for horticultural lighting? | Specify the required PPFD measurement locations and the intended lighting arrangement. |

When comparing supplier samples, agree on the operating settings and measurement geometry first. Keep a record of the sample reference and test conditions alongside each result, particularly when comparing different batches or replacement products.
For a showroom, office, retail space or other installation, prepare a measurement plan showing the locations to be checked. Include the relevant project requirements so the results answer a clear acceptance question.
Before selecting a meter for a test procedure, list the required parameters, expected light levels and reporting format. Confirm that the instrument's range and available functions match the intended method.




Decide how measurements will be named and organised before starting a comparison. A useful record identifies the light source, location, operating conditions and acceptance criteria, making it easier to review results with colleagues or suppliers.
If computer-based reporting is required, include your operating system and required output format in the enquiry so software compatibility can be checked.
For a Sekonic C-7000 quotation, provide the required quantity, delivery country and intended application. Mention any specific colour metrics, reporting requirements or calibration documentation needed with your purchase.
