Q1: What is the difference between ALTR0147 (11W) and ALTR0148 (8W)?
A1: The ALTR0147 is the higher-power, anti-glare variant at 11W / 960lm (31% brighter than the 8W ALTR0148 at 730lm). Both share identical AC230V Class I architecture, CRI>92, beam angles (15°/24°/36°/50°), adjustability, and track compatibility. The ALTR0147 features a dedicated anti-glare design (deep-set reflector housing) for commercial environments, while the ALTR0148 is a lower-power option for lighter accent applications.

Q2: What does the anti-glare design actually do?
A2: The anti-glare (防眩) design uses a deep-set optical housing and precision reflector that shields the LED source from direct line-of-sight at typical viewing angles (0°–45°). This significantly reduces UGR (Unified Glare Rating) and visual discomfort — critical for retail stores, offices, and galleries where customers and staff are exposed to track lighting for extended periods.

Q3: Is the ALTR0147 compatible with the ALPHALUCE TOUR magnetic track system?
A3: No. The ALTR0147 is an AC230V mains-voltage fixture (Class I) with a built-in driver, designed for standard 3-wire/phase AC track systems. It is not compatible with the DC48V Class III TOUR magnetic track system. For TOUR magnetic track, please use the ALTR0178–ALTR0206 series.

Q4: What are the beam angle options and coverage areas?
A4: The ALTR0147 offers four beam angles: 15° (ultra-narrow pinpoint — ~0.53m diameter at 2m), 24° (standard accent — ~0.85m at 2m), 36° (broader fill — ~1.3m at 2m), and 50° (wide flood — ~1.86m at 2m). The 50° angle is particularly useful for general ambient illumination in commercial settings.

Q5: Is the ALTR0147 suitable for outdoor use?
A5: No. The ALTR0147 has an IP20 rating and is strictly for indoor use. It is designed for commercial retail, galleries, hospitality, offices, and residential interiors.

Q6: What is the lumen output and how does it perform in commercial settings?
A6: The ALTR0147 delivers 960lm at 11W — significantly brighter than the 8W ALTR0148 (730lm) and well-suited for commercial retail, showrooms, and gallery accent lighting. With 87.3 lm/W efficacy, it balances brightness with energy efficiency.

Q7: Does the ALTR0147 require an external driver?
A7: No. The ALTR0147 has a built-in AC driver and connects directly to AC230V-50Hz mains power via a standard 3-wire track system. No external power supply unit is required — unlike DC48V Class III magnetic track fixtures.

Q8: Can the ALTR0147 be dimmed?
A8: Yes. When paired with a compatible phase-cut (trailing edge or leading edge) dimmer on the AC230V mains circuit, the ALTR0147 supports smooth dimming for dynamic scene control in commercial and hospitality settings.
