Insights on lighting sourcing and the trade
Short reads on how the platform works, what the Guzhen cluster means in practice and which references are worth checking before a luminaire is specified.
Three places to start
A second revenue stream for electrical installers
From installation only to taking part in the lighting recommendation, without changing the existing trade.
Running a lighting business without a shop or inventory
Six traditional costs, and which of them the cooperation model removes.
Why the Guzhen lighting cluster matters
Finding products, covering categories and dividing fulfilment work.
Three verifiable checks when selecting luminaires
These are published standards and public data, not platform performance figures.
Illuminance has a published standard
GB/T 50034-2024 gives residential values: 100 lx for general living-room activity, 300 lx for reading and writing, 75 lx for general bedroom activity, 150 lx on the dining table and 300 lx on kitchen worktops; Ra ≥ 80 in commonly used rooms.
Certification can be verified
The CNCA implementation rules for lighting electrical appliances place fixed, recessed and portable general luminaires in the CCC catalogue, based on GB 7000.1 series plus GB 17743 and GB 17625.1. Certificates are searchable at cx.cnca.cn.
The cluster has official figures
Zhongshan municipal government information describes Guzhen as supplying more than 70 percent of the domestic and more than 50 percent of the global lighting market, exporting to over 140 countries and regions.
