LUX CHECK at US$15: LUXGRID's international lighting-calculation price memo
LUX CHECK gives one standard calculation area a clear US$15 master price, with no area-size or light-quantity surcharge inside the defined scope.
One clear master price for a clearly defined lighting check
LUXGRID has set the international LUX CHECK master price at US$15 through 21 October 2026. The offer is built for customers who already know the X by Y luminaire arrangement they want checked and need a professional calculation of how that supplied layout performs.
USD remains the fixed master price. The website can display daily local-currency equivalents for convenience, but those figures move with the exchange rate. The final scope is reviewed against the information and files submitted with the quotation.
What the US$15 LUX CHECK scope includes
The standard scope covers one calculation area, one mounting height, one luminaire type with suitable IES or LDT data, and one customer-supplied uniform X by Y grid. LUXGRID checks the modelled illuminance performance and standard uniformity result for that arrangement using the information provided.
The customer should provide the usable length and width, the relevant height, the X and Y quantities, and the exact photometric file for the proposed luminaire. LUX CHECK is a validation route for a supplied arrangement; it is not a full lighting proposal or a substitute for site verification, electrical design, authority requirements or professional approval outside the agreed lighting scope.
No area-size limit and no light-quantity surcharge—within the standard scope
A larger rectangular area does not automatically cost more, and a higher X by Y quantity does not automatically add a luminaire-count fee. The US$15 price remains available when the job is still one standard calculation area, one height, one light type, one supplied uniform grid, a normal LUX CHECK outcome, one revision round and the flexible service queue.
Terms still matter. Multiple spaces, multiple mounting heights, several luminaire types, irregular or obstruction-heavy geometry, manual positioning, full layout design, urgent turnaround, extra revisions, alternative comparisons, glare or emergency checks, compliance schedules, tender-level reporting and other advanced deliverables are priced through the full quotation engine.
If you know the target lux but not the X by Y quantity
Choose the LUX TARGET add-on inside the quotation engine when the average-lux target is known but the required uniform X by Y quantity is not. For a basic standard scope, LUX TARGET adds US$3 to LUX CHECK, producing a US$18 total. LUXGRID then calculates the required grid from the stated target using the supplied geometry and photometric data.
The target should come from the project brief or the responsible project team. Reaching one average value does not by itself establish compliance: uniformity, glare, emergency performance, calculation surfaces and any applicable standard may need separate review.
A small calculation should receive a small, transparent price
LUX CHECK separates a quick, well-prepared validation task from a complete lighting-design assignment. Customers with the right inputs do not need to pay a full proposal fee simply to learn whether a known grid reaches the intended illuminance result.
When a project needs more, the same guided quotation engine adds only the relevant scope. That keeps the entry service simple while allowing larger, more technical or faster projects to be matched with the work they actually require.
Frequently asked questions
Is LUX CHECK really US$15 regardless of room or warehouse size?
There is no area-size surcharge inside the defined standard scope. The project must remain one calculation area, one height, one luminaire type and one supplied uniform X by Y grid. Complex geometry, multiple areas or other additions are priced separately.
Is there a limit on the number of luminaires in the X by Y grid?
LUX CHECK does not add a light-quantity surcharge for the supplied uniform grid. The flat price applies while the rest of the job stays within the standard scope and the files are suitable for calculation.
What must I send for a LUX CHECK?
Send the usable area dimensions or clear drawing, relevant height, X and Y luminaire quantities, exact luminaire model, and a suitable IES or LDT photometric file. Include the result or target context you need reviewed.
What if I need LUXGRID to find the required X by Y quantity?
Select the LUX TARGET add-on in the quotation engine and enter the average-lux target. It adds US$3 to a basic standard LUX CHECK scope, making the basic total US$18.
Why does the local-currency amount change?
The permanent master price is in USD. Local-currency equivalents are refreshed using the latest available daily exchange rate, so they can move while the US$15 master price remains unchanged during the stated validity period.
