Terms of Service

By using Recessed Light Calculator, you agree to the terms below. If you don't agree with any part of them, please don't use the site.

Planning Estimates, Not Professional Advice

Every calculator on this site runs the IESNA lumen method to produce a planning-level estimate — fixture count, spacing, wall offset and illuminance. These results are not a substitute for a stamped photometric design, a licensed electrician's assessment, or a review against local electrical code. Always confirm specifics with a qualified professional before purchasing fixtures or beginning installation work.

No Warranty

Recessed Light Calculator is provided "as is," without warranty of any kind, express or implied, including but not limited to accuracy, fitness for a particular purpose, or non-infringement. We do not guarantee that any calculation will match the results of a full professional lighting design.

Limitation of Liability

To the fullest extent permitted by law, Recessed Light Calculator and its operators are not liable for any damages — direct, indirect, incidental or consequential — arising from your use of this site or reliance on its calculations, including damages related to installation errors, code violations, or property damage.

Acceptable Use

Use this site for lawful, personal or professional lighting-planning purposes only. Don't attempt to disrupt the site, scrape it at a scale that degrades service for other visitors, or misrepresent content from this site as your own without attribution.

Intellectual Property

The design, text, and calculator tools on this site are the property of Recessed Light Calculator. You may link to any page freely; reproducing substantial portions of the content elsewhere requires permission.

Changes to These Terms

These terms may be updated occasionally as the site changes. Continued use of the site after an update means you accept the revised terms. See the privacy policy for how we handle data, or the contact page with any questions.
