Project inquiry
Send an existing drawing, share reference images, or describe the look you want. If you don’t have CAD drawings, we’ll prepare them free of charge.
Custom production starts only after you’re happy with and approve the design. Select the free CAD option below if you’d like us to prepare the drawings.
Before production
Start with an existing CAD package, or send the reference image, product link, sketch, room plan, or 3D model our project team should develop into a drawing.
Depending on the fixture, we may adapt dimensions, light arrangement, hanging length, canopy size, material, finish, glass or stone selection, color temperature, voltage, dimming, mounting details, and quantity. All requests remain subject to engineering, material, electrical, and production feasibility.
Custom production time varies by product. Contact customer service; our team will reply after reviewing your message and discuss the production and delivery schedule with you. Standard orders: approximately 7 calendar days to prepare, then 21–30 calendar days in transit. Allow approximately 28–37 calendar days total. Oversized curbside freight: approximately 45 calendar days in transit, or 52 days total with standard preparation. Custom production and delivery timing are confirmed with customer service. Export/import customs clearance, import duties, and import taxes included. Applicable sales tax is shown at checkout.
A 35% deposit of the confirmed custom-order total begins approved production. The remaining balance is due before shipment. We do not begin production until the CAD or dimensioned drawing, written specification, timing, price, and project conditions are accepted. Any later change request is reviewed for feasibility and its effect on price and timing before work continues.
Questions
Often, yes. Common requests include changes to size, finish, hanging length, color temperature, voltage, dimming, or quantity. Feasibility varies by fixture and requested modification.
If you already have CAD or dimensioned drawings, send them with the ceiling plan, target size, suspension, electrical requirements, finishes, and quantity. If you do not have CAD, send the desired product or inspiration image, sketch, room or ceiling plan, 3D model, and the dimensions you know. You can paste an accessible shared-folder link in the form or email files after submitting.
Approval depends on the fixture and material. We may use a digital reference, material photograph, production sample, physical sample, or another written approval method. Availability, cost, shipping, product-specific timing, and any return requirement for a sample are confirmed before you proceed. Screen colors are reference-only, and natural or handmade materials can vary.
Yes. An existing CAD package is reviewed and revised where required; if you begin with a reference image or 3D model, our project team develops a dimensioned drawing for the fixture. You confirm the drawing in writing before the quotation and production terms are finalized. The project documents identify the included dimensions, materials, finish, suspension, electrical details, and any installation or assembly information. A qualified local electrician or contractor must still verify site conditions, structural support, code, and installation requirements.
Custom-project arrangements vary by product, size, destination, and delivery requirements. Free shipping to the contiguous 48 U.S. states includes export/import customs clearance, import duties, and import taxes. Applicable sales tax is shown at checkout. The written proposal confirms packing, production and delivery timing, access, unloading, and any appointment or signature requirements for the booked service. Standard orders: approximately 7 calendar days to prepare, then 21–30 calendar days in transit. Allow approximately 28–37 calendar days total. Oversized curbside freight: approximately 45 calendar days in transit, or 52 days total with standard preparation. Custom production and delivery timing are confirmed with customer service. Export/import customs clearance, import duties, and import taxes included. Applicable sales tax is shown at checkout.
Return and cancellation eligibility varies by product and modification. The applicable conditions are confirmed in writing before production; customized products are not covered by one blanket return rule. Confirmed defects, wrong items, missing parts, or shipping damage remain subject to review under the published policies.
Documentation and certifications vary by model, configuration, and production batch. Include any required listing, dimming protocol, voltage, or document in the inquiry so availability can be confirmed before ordering. A qualified electrician should verify site and installation requirements.
