Buyer Questions

Questions About These Guides

Where does the data in these guides come from

From the specification text published for the models on this site, plus the company facts on the About page. Nothing is estimated.

Can you advise on a specification we already have

Yes. Send the specification over WhatsApp or email and it will be checked against the models that can meet it.

Do you publish photometric files

Beam data appears on a product page where the factory sheet states it. Ask by model number for anything more detailed.

Can we reuse this material in our own catalogue

Ask by email. Product images and specification text can be supplied for distributors selling the range.

Cannot Find the Answer

Ask the question directly. If it belongs in a guide it will end up in one.
