Twelve guides on specifying commercial LED lighting, written around the figures we publish for our own catalogue: beam angles, cutouts, reflector finishes, chip platforms and how to source an OEM programme.

Design Guide How to Choose a Beam Angle for Commercial Lighting Beam angle decides whether light lands on the merchandise or on the floor beside it. A practical method for picking between 5° and 60° optics by ceiling height and target.

Buying Guide Anti-Glare Downlight Buying Guide for Commercial Projects What actually makes a downlight comfortable: source depth, reflector coating and aperture geometry, and how to check them on a sample before you order.

Comparison LED Spotlight vs Track Light Which to Specify Recessed spotlights and track heads solve the same problem in different ways. A comparison across ceiling type, flexibility, cost of change and appearance.

Installation Guide Ceiling Cutout Size Guide for Recessed Lighting The cutout ladder used across the YiYo Lighting range, how to plan two or three hole sizes for a whole building, and what to check before the ceiling is cut.

Material Guide COB vs SMD LED Chips for Commercial Fittings Why the catalogue uses COB in spotlights and track heads but SMD in the mini and general downlight models, and what that means for beam control and appearance.

Design Guide Trimless vs Bordered Recessed Fittings Borderless apertures look better and cost more to install. When the difference is worth paying for, and how to run both in one building.

Product Guide Grille Light Selection Guide for Retail Ceilings Single, twin and triple head grille modules compared by opening size, coverage and the kind of display each one suits.

Industry Article Hotel Lighting Specification Guide Lobby, corridor, guest room and joinery lighting, and why hotels are the hardest test of a fitting's glare behaviour.

Industry Article How to Light a Supermarket Aisle Getting light to the bottom shelf from a high ceiling, and why ambient downlighting alone rarely does it.

Buying Guide OEM LED Lighting Sourcing Checklist What to confirm before placing an OEM or ODM lighting order with a Chinese factory, from tooling ownership to batch-to-batch finish matching.

Installation Guide LED Downlight Installation Guide A practical sequence for installing recessed downlights and spotlights, from checking the void to seating trimless housings before the skim coat.

Material Guide Reflector Finishes and Glare Control Gun black, matt black, matt white and bright silver: what each finish does to the beam and to the appearance of the aperture.

Questions

About These Guides

Who writes these guides?

They are written around our own catalogue by the people who specify and sell it, using the published figures for each model rather than general marketing claims.

Can you help with a ceiling layout?

We can shortlist models against a ceiling height, an aperture and an application. Full lighting design calculations are normally done by the project's lighting designer.

Do you have downloadable documents?

Yes, the Download Centre carries the catalogue and per-range specification sheets built from the same published figures.
