T4 LED Bulbs FAQs
What is a T4 LED and where is it commonly used?
T4 (1/2 inch diameter) appears in slim under‑cabinet lights, display cases, and compact fixtures needing even, linear output.
Which bases and voltages are typical for T4 LEDs?
Common bases include G8 or GY6.35 at 12 V or 120 V depending on fixture design. Verify base and voltage before buying.
Are T4 LEDs dimmable and which dimmers work?
Many T4 LEDs dim with compatible low‑voltage controls; verify triac/ELV or 0–10 V depending on the driver.
How do I choose lumen output and beam distribution?
Match lumens to your previous lamp and pick omni or directional output based on reflector design and diffusion needs.
Can T4 lamps be used in enclosed or damp fixtures?
Use enclosed‑rated models in sealed housings; select damp/wet ratings as required for baths or covered exteriors.
How do I match T4 LEDs to existing halogen/xenon T4s?
Check base pin spacing, overall length, and voltage/current. Some LED replacements require AC/DC matching or polarity alignment.
What color temperatures and CRI should I consider?
Choose 2700–3000K for warm residential, 3500–4000K for neutral task. CRI 90+ enhances finish and food color accuracy.
Are there special size/clearance considerations for T4 bulbs?
Slim fixtures have tight tolerances—confirm length and width to avoid contact with lenses or reflectors.
Can T4 LEDs be used outdoors or in landscape systems?
Yes—pick outdoor‑rated models and ensure transformer compatibility. Keep connections sealed from moisture.
What quality marks and warranties matter?
UL/ETL listing and a 2–5 year warranty with published lumen maintenance indicate quality.
