Buyer Questions

About the Knowledge Center

Who writes these guides?

They are written from our own product data by the team that builds the fixtures, so every figure quoted matches a datasheet on this site.

Can you advise on a specification before we order?

Yes. Send the application and the constraint you are working to and our engineers will tell you what we would specify.

Do the guides cover installation?

They cover the decisions made before installation: voltage, IP rating, CRI, beam angle, dimming protocol and LED package choice.

Ask an Engineer Directly

If the guide does not answer it, message us. We answer specification questions before there is an order on the table.
