Tekniska guider

3000K eller 4000K spotlights? Välj utifrån utseende, material och omgivande ljus, inte ljusstyrka. Jämför lumen, CRI och SDCM och testa sedan prover.

Vad är en 3-fas skenspotlight? Lär dig hur skenor med tre kretsar fungerar, varför de inte kräver trefasmatning, hur grupper och DALI-styrning fungerar och vad du bör kontrollera.

Plan 2m LED track lighting step by step: kit contents, circuits, head layout, joining two 1m rails, cutting, centre power points, installation and upkeep.

Plan 3 circuit track lighting step by step: circuit groups, supply and switching, I/L/T/X connectors, orientation, feed points, LED inrush and a full BOM.

Compare 240V, 48V and 24V track lighting by power supply, current, voltage drop, controls, installation and cost, with a decision table for projects.

Track lighting with adjustable heads leaving bright spots and dark corners? Re-aim heads, check beam spread and overlap, and see when that is not enough.

What lights fit a 10mm magnetic track? See which module types exist, why 10mm alone does not guarantee a fit, and six checks to run before you order.

Three or four heads on a 1.5 m track light? Work out the head count from your lighting targets, beam coverage, spacing and the track’s rated capacity.

Choose smart LED lighting control for commercial projects: functions first, then wired or wireless, DALI, Zigbee, Casambi or WiFi, and what to specify.

How much can office LED lighting save? Use DOE retrofit ranges, then calculate kWh, cost savings and simple payback from your own wattage and hours.

Choosing an LED light factory in China? Check legal entity, product fit, quality system, compliance files, sample and batch consistency before ordering.

Office lighting standards explained: EN 12464-1 500 lx for desk tasks, how IES RP-1-24 and WELL differ, and what to check beyond one lux number.
