Start with the application, not the wattage
Separate guest rooms, corridors, restaurants and public areas before selecting a lamp. Guest rooms normally need warm, comfortable light and predictable dimming. Corridors may prioritize lifetime and controlled beams. Restaurants need strong color rendering so food, finishes and skin tones remain natural.
For retrofit projects, record the existing socket, fixture dimensions, supply voltage and dimmer model. A lamp that performs well on an open test bench can behave differently inside a compact downlight or enclosed decorative fixture.
Control color consistency across rooms
Specify both CRI and color consistency. Ra90 is suitable for many general areas, while Ra95 or Ra98 is valuable in premium rooms, restaurants and retail-style hotel spaces. A target of three-step SDCM or better helps reduce visible color differences between lamps installed side by side.
Ask the supplier how color is controlled between production batches. A sample is useful, but long-term projects also need repeatability when replacement lamps are ordered months later.
Test the real dimmer and fixture
TRIAC compatibility cannot be judged only by the word “dimmable” on a data sheet. Evaluate minimum dimming level, visible flicker, startup behavior, noise and stability with the actual dimmer used by the project.
Thermal conditions matter as well. In a confined fixture, heat can shorten driver and LED life. TECO GU10 options use intelligent thermal protection that gradually reduces power when temperature becomes excessive and restores output as the lamp cools.
Qualify the supply plan
Confirm warranty terms, certification, surge protection, lead time and packaging before approval. For private-label programs, define the carton, label, color-temperature marking and traceability requirements early.
A paid sample order should reproduce the intended configuration. Provide the supplier with the target market, annual volume, dimmer information and fixture type so the evaluation sample represents the final application.
