All listed models: 230V, 2700K, Ra 90, dimmable. Values are nominal product specifications, not individual sample measurements. Other voltage and CCT configurations require confirmation for the selected model.
Base & Dimensions
S14d: one central connector on the tube. S14s: two separate connectors on the tube. Specify the base when requesting samples and match it to the fixture lampholder.
The models in the table use a 30 mm tube diameter. Check overall length, connector position and fixture clearance before ordering. Request the model-specific drawing when developing or replacing a luminaire.
Mirror & Linear Lighting Applications
Mirror and vanity lighting
For bathroom mirror luminaires, dressing-room mirrors and hotel vanity fixtures designed for the selected linear bulb and base.
Wall and picture lighting
For slim wall luminaires and picture-light designs where the tube length, light output and glass finish are part of the fixture specification.
Bathroom suitability depends on the complete luminaire and installation location. Confirm the fixture protection rating, lampholder and thermal conditions; the bulb alone does not establish the fixture's suitability.
Project Options
Voltage and color temperature
230V is the listed EU configuration. Ask about 120V / 60Hz versions for US projects. CCT options include 2200K, 2700K, 3000K, 4000K and 6500K, subject to the selected configuration.
Color quality and dimming
Specify the required SDCM bin (3, 5 or 6) and R9 target (>50 or >80). Confirm the driver configuration, dimmer pairing and minimum stable light level with samples.
Fixture compatibility
Enclosed-fixture use is listed for the series. Confirm temperature performance in the actual luminaire, especially for enclosed mirror-light designs.
Warranty and project documentation
Two-year warranty. Confirm the applicable LVD, EMC and RoHS documentation for the ordered configuration and target market when requesting a quotation.
Production & Sample Review
For sample approval, specify the model, voltage, CCT, dimmer, lamp quantity and fixture conditions. Include any power-factor, color-consistency or flicker requirements so the configuration and test conditions can be agreed before production.
