Products and Product Information

We aim to describe our lighting products, dimensions, finishes, materials, compatibility, and images accurately. Measurements may have reasonable manufacturing tolerances, and colors or finishes may appear different depending on lighting and display settings. Product specifications may be updated when necessary.

Pricing and Orders

Prices, promotions, and availability may change without notice. We reserve the right to correct obvious errors in pricing, product information, or availability and to cancel or limit an order when reasonably necessary, including for suspected fraud or inventory errors. If we cancel a paid order, the applicable payment will be refunded.

Payments are processed through Shopify and available payment providers. You agree to provide valid billing and payment information and authorize the applicable charges for your order.
