Total PAR / PPFD
Measure the combined photosynthetic photon flux density at the measurement point.
Grow Light Measurement · PAR + UVA + RGB
See more than one PAR number.
X100 combines total PAR/PPFD, UVA irradiance and separate red, green and blue PAR components in one app-connected measurement workflow. Estimate DLI, map fixture uniformity and export XLSX data for deeper comparison.
Built for grow-light checks, fixture comparison, grid measurement and data-driven lighting decisions.

More Measurement Context
Go beyond total PPFD.
A single PAR value tells you total plant-light intensity at one point. X100 adds UVA and three broad visible PAR bands so you can compare how different grow lights deliver that total.
UVA Irradiance
Add a separate UVA reading when evaluating grow lights that include supplemental UVA output.
RGB PAR Components
Review red, green and blue PAR contributions as measured photon-flux components, not just a color percentage.
Exportable Data
Save measurement grids as XLSX files for records, spreadsheets, analysis and later visualization.
PAR + UVA + RGB PAR Breakdown
See how the total PAR is distributed across three broad color bands.
X100 displays total PAR together with UVA and separate red, green and blue PAR components. This is useful when two fixtures produce similar total PPFD but use different spectral balances.
Red PAR600–700 nm
Green PAR500–600 nm
Blue PAR400–500 nm
X100 provides three broad RGB PAR bands. It should not be described as a full wavelength-by-wavelength spectrometer.
Estimated DLI Calculator
Turn a current PPFD reading into an estimated daily light total.
Select the lighting duration and use the current PPFD reading to estimate Daily Light Integral. This makes it easier to translate an instantaneous measurement into a daily-light planning number for controlled lighting schedules.
Estimated DLI assumes the selected PPFD remains representative during the chosen lighting period. Real DLI can differ when light output, dimming or natural sunlight changes over time.
PAR Mapping / Uniformity Test
Measure the whole grow area, not just the center.
Create a measurement grid, record PAR at each point and let the app summarize the grid with average PAR and uniformity U0. This helps compare center-to-edge performance, fixture height, spacing and dimmer settings.

Measure More Than Total PAR
Useful when the question is intensity, spectral balance and distribution.
X100 is designed for users who want more context around a grow light than one center PPFD reading. Total PAR shows intensity, UVA adds ultraviolet information, RGB PAR components show broad-band contribution, and grid testing shows how the fixture performs across space.

Choose the Right EvoDevice Tool
X100 and EVO-100 solve different measurement jobs.
Use X100 when you want active spot measurements, RGB PAR breakdown, mapping and spreadsheet export. Use EVO-100 when the priority is fixed-position WiFi monitoring over time.

X100 FAQ
Common questions about X100.
What does the EvoDevice X100 measure?
X100 measures total PAR/PPFD, UVA irradiance and separate red, green and blue PAR components. It also supports estimated DLI, multi-point PAR grid measurement, uniformity review and XLSX export.
Are the red, green and blue values percentages?
No. The supplied X100 materials present the RGB values as PAR components in µmol/(m²·s): blue 400–500 nm, green 500–600 nm and red 600–700 nm.
Is X100 a full spectrometer?
No. X100 provides three broad RGB PAR bands rather than a full wavelength-by-wavelength spectral graph. This makes it useful for broad spectral-balance comparison without describing it as a full spectrometer.
Can X100 calculate DLI?
X100 provides an estimated DLI calculator based on the current PPFD reading and the lighting duration you select. The estimate is most representative when PPFD remains relatively stable during that period.
Can X100 test grow-light uniformity?
Yes. The PAR Collector workflow lets you set a grid, record multiple measurement points and review average PAR together with uniformity U0.
Can I export the measurement data?
Yes. X100 can export measurement results as an XLSX spreadsheet file for record keeping, comparison and further analysis.
Does X100 itself create an AI heatmap?
X100 exports the measured grid data. You can then use the XLSX file with the spreadsheet or AI analysis tool of your choice to create a heatmap or other visualization.
Should I choose X100 or EVO-100?
Choose X100 for active spot measurement, RGB PAR breakdown, grid mapping and XLSX export. Choose EVO-100 for fixed-position WiFi monitoring of PPFD/PAR and UVA over longer time periods.
Measure the light. Keep the data.
Use X100 to compare total PAR, UVA, RGB PAR components and fixture uniformity — then export the results for your own records and analysis.
