Frequently Asked Questions
What is the difference between BY778P PSU, PSD, and BY778X?
BY778P PSU is the fixed output (On/Off) version with the highest efficacy of 190 lm/W. BY778P PSD is the DALI-2 dimmable version at 180 lm/W, suitable for wired dimming systems. BY778X (also labeled BY778P SIA) is the Interact IoT smart version with an integrated SNH210IA sensor for wireless connectivity, remote monitoring, and group control.
What mounting options are available for the GreenPerform Elite Highbay G2?
Three mounting options: (1) Hook suspension — standard hook included, compatible with chain or cable; (2) Pipe mount via G1/2 thread; (3) Surface/wall mount using the optional BY778Z Bracket (12NC: 911401637409). A safety cable (≥SUS304 Ø3mm) is recommended for all suspended installations.
What is the warranty and expected lifetime?
All BY778P/BY778X variants come with a 5-year warranty. The rated lifetime is 100,000 hours at L70B50 under Ta 35°C operating conditions, equivalent to over 11 years of continuous 24/7 operation.
Which beam angle should I choose — WB or NB?
Wide Beam (WB, 90°±5°) is recommended for general area illumination in warehouses, manufacturing floors, and logistics centers where broad, uniform coverage is needed. Narrow Beam (NB, 55°±5°) is ideal for high-rack aisles, tall ceilings, and applications requiring focused light distribution with higher intensity.
Is the BY778P compatible with smart lighting control systems?
Yes. The BY778X variant (Interact SIA) is specifically designed for Interact IoT connectivity with an integrated SNH210IA sensor supporting wireless commissioning, grouping, and energy monitoring. The PSD variant supports DALI-2 wired dimming. For custom control protocols, ETO (Engineer-to-Order) options may be available — contact sales@honnexlighting.com for details.
What are the main improvements over the previous generation BY718P?
The G2 delivers: 190 lm/W vs 160 lm/W efficacy (+19%), 40,000 lm max vs 30,000 lm output (+33%), 100K hrs vs 75K hrs lifetime (+33%), IP66 vs IP65 ingress protection, flicker-free certification (SVM<0.4), Interact smart control option, and an upgraded 5-year warranty vs 3 years.
