Frequently Asked Questions (FAQ)
In-depth technical and commercial answers addressing procurement, certifications, wiring topologies, and OEM customizations for global distributors.
What is the key difference between a standalone LED tube and an integrated lamp tube (batten)?
A standalone LED tube (such as a retrofit T8) requires a separate external luminaire housing, tombstones/sockets, and specific internal wiring (bypassing ballasts). An integrated lamp tube combines the LED light source, optical diffuser, structural heat sink chassis, and isolated LED driver into an all-in-one sealed luminaire. Integrated battens provide superior IP sealing (IP65/IP66), streamlined physical installation via surface mounting clips or suspension wires, and significantly better thermal dissipation directly along the full aluminum structural backing.
What specific CE directives must be satisfied for 4FT integrated lamp tubes entering the EU?
Three primary European directives are required for CE marking:
1. Low Voltage Directive (LVD) 2014/35/EU: Enforced via EN 60598-1 and EN 60598-2-1, testing electrical insulation, creepage distance, terminal blocks, and resistance to electrical shock.
2. Electromagnetic Compatibility (EMC) Directive 2014/30/EU: Evaluated under EN 55015 for conducted/radiated emissions and EN 61547 for electrical immunity and transient surge protection.
3. RoHS Directive 2011/65/EU and amendment (EU) 2015/863: Prohibiting specific hazardous substances across all internal electronic components, plastics, and solder alloys.
Can your 4FT integrated tubes be connected in continuous linear rows (daisy-chained)?
Yes. Scoden designs integrated battens with optional through-wiring systems (3-core or 5-core for DALI/emergency configurations) equipped with male-female quick-connect push-in terminals. Depending on driver inrush current and continuous loop loading limits, up to 20 to 30 units can be safely daisy-chained across a single AC 230V circuit breaker line.
What is the difference between an LED tri-proof light and an LED explosion-proof light?
A tri-proof light is sealed against water, dust, and corrosion (typically IP65–IP66 rating) and is intended for harsh industrial sites such as car parks, cold storage, food manufacturing, and logistics warehouses. An explosion-proof light is additionally engineered and certified under ATEX/IECEx standards to contain any internal electrical spark or explosion without igniting the surrounding hazardous atmosphere, specifically specified by gas groups (IIA, IIB, IIC), dust zones (20, 21, 22), and temperature classes (T1 to T6).
Do you provide IES files for lighting layout calculations (Dialux/Relux)?
Yes. Every luminaire series engineered by Scoden is measured in our in-house optical darkroom using a precision distributed goniophotometer. We supply native .IES and .LDT photometric data files along with comprehensive test reports detailing lumen output, CRI, beam angles, and power factors upon project inquiry.
What OEM, ODM, and SKD services does Scoden offer to global clients?
We provide full-spectrum engineering support: private mold design for custom profiles, customized driver wattage and CCT configuration, bespoke silk-screen branding and multi-language retail packaging, and Semi-Knocked-Down (SKD) kits for buyers looking to carry out final assembly in their home countries to lower local import tariffs.
Where is the factory located, and can our engineering team perform an audit?
Our manufacturing facility is located in Beibaixiang Town, Yueqing, Wenzhou, Zhejiang Province, China — widely recognized as China's Electrical Capital. We welcome on-site buyer factory audits as well as live remote video inspections of our assembly, aging, and photometric facilities.
